Denaturation by Heat to separate double-stranded DNA into two single strands
1
Annealing Primer to Target Sequence
The primers that anneal (bind) to the complementary sequence marks the DNA target sequence
4
Extension
New double stranded DNA molecules that is identical to the original double stranded target DNA region is formed
3
End of the First PGR Cycle
Fresh DNA polymerase is added
The correct sequence of steps in a PCR cycle is 2 (denaturation), 1 (annealing), and 4 (extension), where DNA is first denatured, then primers anneal, and lastly, DNA polymerase extends the primers to create new DNA strands.
The process begins with denaturation, where the mixture is heated to a high temperature (around 95 0C) to separate the double-stranded target DNA. Following that, annealing occurs when the temperature is decreased to allow the primers to hybridize to the target DNA. The final step is extension, where DNA polymerase extends the primers to make a copy of the target DNA. Therefore, the sequence is denaturation (2), annealing (1), and then extension (4).
It should also be noted that fresh DNA polymerase is not added in every cycle, because the DNA polymerase used in PCR is heat-stable and can withstand multiple cycles of PCR without degradation. The optimal temperature for the DNA polymerase's activity is around 72 0C, which facilitates the synthesis of a new DNA strand complementary to the DNA template strand.
The energy available to consumers determined by subtracting the energy used by plants from the total energy transformed by the process of photosynthesis. True or False
Answer:
True
Explanation:
during photosynthesis, plants store up energy as starch, it is this starch that is the energy available to herbivours. thus the energy available to herivours is the is energy left from the difference between total energy produced during photosynthesis and the energy used by plants for the process.
Answer: false
Explanation: The law of transformation of energy states that energy can neither be created nor destroyed but are transformed from one form to another. Plants are the producers. They trap solar energy from the sunlight and transforms it into chemical energy. This chemical energy is then utilized by consumers. Hence Solar energy =chemical energy
A scientist claimed that hemophilia is caused by a functional deficiency in Factor VIII. The evidence in the passage that would best support this claim is that Factor VIII is:
A.a soluble blood protein.
B.produced by a gene on the X chromosome.
C.able to relieve hemophilia symptoms.
D.encoded by a gene that contains introns.
Answer:
C. able to relieve hemophilia symptoms.
Explanation:
Hemophilia is a genetic disorder. It is an X-chromosome linked recessive disorder. It is caused by deficiency of functional blood clotting factor VIII. The Functional factor VIII al deficiency may be inherited or arise from spontaneous mutation.
The symptoms of hemophilia can be reduced partially by functional Factor VIII. This will help to counter functional deficiencies in factor VIII in the haemophilic individuals.
Hunger is best described as__________.
A) a physiological desire to consume food.
B) a psychological desire to consume food.
C) eating that is often driven by environmental cues.
D) eating that is often driven by emotional cues.
Answer:
A) a physiological desire to consume food is the correct answer.
Explanation:
Hunger is a feeling that the person needs food to eat.Hunger makes the body weak and vulnerable to infections because the body does not get adequate food to fight against the infections and due to hunger people suffer from malnutrition and if children remain hungry they often have abnormal in their growth.hunger is caused because of poverty, job instability, food shortages, poor infrastructure, nutritional quality.Symptoms of hunger are:Feeling of growling and emptiness in the stomach.DizzinessGurgling in stomachnot able to concentrationheadacheirritabilitynauseaAnswer:
Hunger is a physiological desire to consume food.
Explanation:
Hunger is a physiological process controlled by the hypothalamus.
This helps in the secretion of different hormones that enhance the desire of hunger.
When someone eats carbohydrates rich food, insulin is secreted which uses the sugar. When there is no sugary food the insulin secretion is less.
When the person eats lipid food, another hormone will secrete called leptin. It helps in the release of energy to use in physiological activities.
Ghrelin is another hormone responsible for stomach cramps. When someone is hungry, the secretion of ghrelin is more to increase hunger. This is the very reason if a person awake at night he/she feels frequently hungry.
In what type of circulation does the blood flow between the heart and lungs?
Answer:
Pulmonary circulation
Explanation:
The pulmonary circulation is the type of circulatory system that involves the flow of deoxygenated blood from the right ventricle of the heart to the pulmonary trunk, which transports the deoxygenated blood through the right and left pulmonary arteries to the capillary beds and arterioles of the lungs. An exchange occurs in the lungs as oxygen is absorbed from the alveoli, while carbon dioxide is released. The oxygenated blood is then returned to the left atrium and ventricle of the heart.

All life depends on the availability of usable energy. This energy is released when
(1) organisms convert solar energy into the chemical energy found in food molecules(2) respiration occurs in the cells of producers and high-energy molecules enter the atmosphere(3) cells carry out the process of respiration(4) animal cells synthesize starch and carbon dioxide
Answer:
3 (Cells carry out the respiration process)
Explanation:
Cellular respiration is a metabolic (catabolic) process common to all living things as all living things need energy for their life processes.
Respiration is the biochemical process in which the cells of an organism obtain energy by breaking down organic molecules in presence or absence of oxygen (aerobic or anaerobic) resulting in the release of Carbondioxide (CO2), water and Adenosine triphosphate (ATP).
Food molecules (containing stored energy in their chemical bonds) absorbed after digestion are broken down and the energy within their molecules are freed. This freed energy in form of ATP, is used to power the organism's movement and physiological functions.
Note that, ATP is an energy carrying molecule and a usable form of energy by cells. This is so because ATP releases energy quickly. Energy is released from ATP when the end phosphate (Pi) is removed to become ADP (adenosine diphosphate), which is a low energy molecule.
Aerobic cellular respiration consists of Glycolysis, Kreb's cycle and Oxidative phosphorylation. A total of 38 ATP molecules is produced in the cytosol of prokaryotes while a total of 36 ATP molecules is produced in the mitochondria of eukaryotic cells.

Match the gastric phase on the left (1-3) with the correct description on the right (4-6):
1. intestinal phase 4. prepares stomach for arrival of food
2. gastric phase 5. stomach empties and decreases secretions
3. cephalic phase 6. stomach secretes juice and mixes food into chyme
Answer:
1 and 5,
2 and 6,
3 and 4
Explanation:
Intestinal phase: stomach empties and decreases secretions
The intestinal phase is the phase where stomach empties its contents(chyme) and decreases secretion. In this stage the duodenum responds to arriving chyme and moderates gastric activity through hormones and nervous reflexes.
The Chyme is the semi-fluid mass of partly digested food that is expelled by the stomach, through the pyloric valve, into the duodenum.
Gastric phase: stomach secretes juice and mixes food into chyme
The gastric phase is a period in which swallowed food and semi-digested protein ( peptides and amino acids ) activate gastric activity which secretes juice and mixes food into chyme. About two-thirds of gastric secretion occurs during this phase.
Cephalic phase: prepares stomach for arrival of food
The cephalic phase of digestion is the gastric secretion that occurs prior to when food enters the oral cavity. Cephalic phase result from the ignition of visual, olfactory, and auditory inputs to the brain and also induce anticipatory responses i.e prepare the gastrointestinal tract for the meal.

Explanation:
Plants and algae most recently shared a common ancestor 480 million years ago, and plants colonized land shortly after that. Light, water, minerals, and dissolved gases surround the whole body of a submerged green alga, and the buoyancy of water provides physical support. What evolved in terrestrial plants to provide support and also transport water and minerals?
Answer:
The correct answer will be- the vascular system
Explanation:
The plants and algae evolved from a common ancestor and studies have also found that the algae-like Chara also evolved into plants.
The plants became adapted to grow in the terrestrial habitat by modifying themselves. The modification was that they developed the vascular system which helps them in conduction of the nutrients and water from the soil to the top of the plants and also the food to every part of the plant.
The plants also added the deposition of the cutin layer over their structure which allows the plants to stand straight and few amounts of loss of water from the plants.
Thus, the vascular system is the correct answer.
A client with atrial fibrillation has been prescribed Coumadin. What is the rationale for this treatment measure?
Answer:
Coumadin is prescribed for atrial fibrillation to thin the blood and prevent the formation of clots.
Explanation:
Atrial fibrillation is characterized by inadequate pumping of blood by the atria to the ventricle. Since,the atria are in a state of fibrillation or shaking, they cannot pump blood to the ventricles. This increases the risk of blood clots forming inside the atria that could potentially increase the risk of heart attack or stroke if the clots get lodged in the coronary or carotid arteries.
Coumadin is blood thinner that minimizes the aforementioned risks.
How did you know that vinegar diffused into the cubes (1 point)? (Remember, as vinegar diffuses into the agar, the agar becomes more acidic. This diffusion causes the phenolphthalein indicator to change from pink to colorless.) Did the diffusion distance differ between the cubes (1 point)?
Answer:
1)Diffusion
2)yes, because of size difference
Explanation:
1) Biological cells live and grow by the inside and outside movement of molecules and diffusion is a process which takes place when molecules move from higher concentration area to lower concentration area. When cubes of agar alongwith indicator (phenophthalein) is added into vinegar, the hydrogen ions move from vinegar into the agar cubes and change in color appears. This change of color indicates the diffusion of vinegar into agar cubes
2) The diffusion distance differs between the cubes because of different sizes of the cubes. The difference in size results in difference of surface area which can be calculated by the volume of the cube. Larger the cube is, the more time vinegar will take to diffuse into the agar cube.
Vinegar diffusion into agar cubes is indicated by the phenolphthalein indicator turning from pink to colorless. The diffusion distance likely differs between cubes of different sizes due to variations in their surface area-to-volume ratios, affecting the rate of diffusion.
The visual indication of vinegar diffusing into the agar cubes can be observed through the colour change of the phenolphthalein indicator, which goes from pink to colorless as vinegar diffuses into the cube, indicating an increase in acidity. This demonstrates the movement of the vinegar into the agar by diffusion. By measuring the cube's cross-section that remains pink, we can assess the distance the vinegar diffused.
Regarding the difference in diffusion distance between the cubes, typically smaller cubes will exhibit a larger proportion of their volume changing color compared to larger cubes. This difference is due to the larger surface area-to-volume ratio in smaller cubes, which facilitates a faster rate of diffusion relative to the larger cubes with a smaller surface area-to-volume ratio.

Although Mr. Yanagita has recently learned to play poker quite well, he cannot consciously remember ever having played poker. It is likely that he has suffered damage to his
a. brainstem.
b. cerebellum.
c. hypothalamus.
d. hippocampus.
e. motor cortex.
Answer:
d. hippocampus.
Explanation:
The hippocampus is where episodic memories are formed and stored to use later. This kind of memories are autobiographical, this means that they are formed from our experiences, for example Mr. Yanagita learning to play poker. We conclude the hippocampus is damaged because Mr. YAnagita can't recall the experience of having played poker before.
I hope you find this information useful and interesting! Good luck.
Mr. Yanagita likely has damage to his hippocampus, resulting in his inability to form conscious memories of playing poker.
Explanation:Mr. Yanagita's inability to consciously remember playing poker despite being good at it suggests damage to his hippocampus, which is responsible for forming new explicit memories. This is supported by the case of H.M., who had his hippocampi removed and experienced significant memory loss. However, his implicit memory, which is controlled by the cerebellum, remained intact. The cerebellum also plays a role in coordinating movement, but it is not directly involved in memory formation.

The other statements are true: b. Fats are an important energy source for our bodies at rest and during low-intensity exercise, as they provide a major source of energy in these states. c. Fats are composed of carbon, hydrogen, and oxygen, which are the elements that make up lipid molecules. d. Fats yield more Calories per gram than carbohydrate or protein; in fact, fats provide about 9 calories per gram, while carbohydrates and proteins only provide about 4 calories per gram.
How did you develop from a single-celled zygote to an organism with trillions of cells?
Answer: mitosis
Explanation:when an egg is fertilized,it becomes a zygote.the zygote is single-cell and undergoes cleavage.cleavage is the mitotic division of a zygote into smaller cells also called blastomere,which forms a spherical mass.
The type of cleavage is dependent on the different animals and whether yolk is present.
As the zygote continues to grow,organs rudiments forms and organs form afterwards, through mitotic division.
In Mitosis the daughter cell has the same number of chromosomes as the parent cell and it is essential in the increase of the number of cells causing growth in multicellular organisms.
Mitosis also helps to regenerate lost body parts.
The excretory system is responsible for moving toxic wastes, dissolved molecules, and excess heat. You would conclude that the excretory system contributes to:_________
Answer:
The excretory system is responsible for moving toxic wastes, dissolved molecules, and excess heat. You would conclude that the excretory system contributes to: Maintaining dynamic equilibrium in the body.
Explanation:
Living cells carry out chemical reactions, necessary for their functioning. These generate several substances, some of which are unwanted by-products and can give the organism if they accumulate. That is why they have developed special mechanisms for the elimination or excretion of these residual products. Excretion is the process by which the body removes metabolic wastes from the body. The excretory system is the set of organs and ducts of the body responsible for the elimination of waste products from the body. Among the substances that the human body must eliminate are carbon dioxide (from cellular respiration), bilirubin (which comes from the degradation of red blood cells), salts, water and urea (product of protein degradation ). These substances are processed in various organs. Excretion processes are important for homeostasis, that is, the maintenance of a constant internal environment (dynamic equilibrium) for body cells.
The excretory system is defined as the system of organs and tissues, which are involved in the function of excretion of toxic substances and reabsorption of essential nutrients and water.
The excretory system contributes to maintaining the dynamic equilibrium of the body.
Functions of excretory system are:The excretory system is a complex set of organs, tissues, and ducts to eliminate the toxic, waste, and unuseful products from the body. The products such as salts, water, bilirubin, and urea are excreted by the excretory system. It is also involved in releasing excess heat from the body.
Thus, the excretory system maintains the homeostasis of the body and the constant internal environment for the body cells.

1. In Texas, the most common causes of collisions include speeding, driving under the influence of alcohol, and _____________.
Answe Running red light and stop signs.
Speeding and failure to yield.
Explanation:
Final answer:
The most common causes of collisions in Texas are speeding, driving under the influence of alcohol, and distracted driving. Distracted driving is especially prevalent among young adult and teen drivers, who are more prone to distraction due to their developmental stage.
Explanation:
In Texas, the most common causes of collisions include speeding, driving under the influence of alcohol, and distracted driving. Distracted driving encompasses various activities that take the driver's attention away from the road, such as eating, reaching for the phone, texting, or any other activity that distracts them from focusing on driving. This is a significant issue among young adult and teen drivers, who have the highest proportion of distraction-related fatal crashes. Additionally, it's important to consider that driving with incomplete brain development can contribute to younger drivers' inability to remain focused and make good decisions, as suggested by the subject's brain development stage.
Certain factors particularly affect older drivers, such as failing eyesight and slower reflexes, combined with rapidly changing traffic conditions, which can increase the risk of accidents.

Which objects in space formed from the huge disk of ice and debris beyond the outer planets? Select two options. Pluto comets Neptune a solar nebula planetesimals
its c and b im sure
Explanation:
Answer:
solar Nebula and planetesimals
Explanation:
About 4.6 billion years ago, a huge cloud of hydrogen gas and dust collapsed under its own weight, eventually flattening into a disk called the solar nebula. Most of this interstellar material contracted in the center of the disk to form the sun, and some of the gas and dust remaining in this solar nebula condensed to form the planets and the rest of our solar system. In short, a solar nebula is a cloud of gas, dust, ice, debris.
The best theory for the formation of the Solar System and, by extension, other planetary systems, says that the remnants of the Sun's formation eventually condensed to form the planets, the protoplanetary disk - a fine interstellar dust that gradually coalesced and joining debris and ice in ever larger and more massive bodies called planetesimals. This growth produced asteroid-sized bodies that, by the same process of collision and agglutination, gave rise to the planets.
Your grandmother unfortunately had a stroke over the weekend. You take her to the doctor, and the doctor says that despite some memory loss, her nondeclarative memory will be fine.With what form of memory will your grandmother likely NOT have any deficits?a. Picture memoryb. Memory for factsc. Memory for skillsd. None of the above
Final answer:
The grandmother with a stroke is likely to maintain her non declarative memory, which includes memory for skills, but may face deficits in declarative memory such as memory for facts.
Explanation:
In the context of memory, non declarative memory refers to the retention of skills and habits, such as how to ride a bicycle or play the piano. It contrasts with declarative memory, which is concerned with facts and events that a person can consciously recollect. Since the doctor mentioned that the grandmother's non declarative memory would be fine despite her stroke, she is most likely to maintain abilities such as memory for skills (option c). On the other hand, the memory for facts, which is part of declarative memory, may be impaired due to the stroke and the ongoing symptoms shared by Rosa's family, indicating issues with cognitive tasks including the management of her finances.
The correct option is c. Memory for skills.
Nondeclarative memory, also known as implicit or procedural memory, refers to the unconscious memory of skills and how to perform them. It is not affected by the type of stroke your grandmother experienced, which typically impacts declarative memory instead. Declarative memory includes memory for facts (semantic memory) and events (episodic memory), both of which are consciously recalled.
Let's consider the options:
a. Picture memory: This is a form of declarative memory, specifically episodic memory, which could be affected by a stroke.
b. Memory for facts: This is also a form of declarative memory, specifically semantic memory, which could be affected by a stroke.
c. Memory for skills: This is a form of nondeclarative memory and is typically spared in cases of stroke, as it is not stored in the same areas of the brain that are often damaged by strokes.
d. None of the above: This option suggests that your grandmother might have deficits in all forms of memory, which is not accurate given the information provided.
Therefore, the most accurate answer is that your grandmother will likely not have any deficits in her memory for skills, which is part of her nondeclarative memory.
Do the new data support the hypothesis that the parasite switched surface glycoproteins once the host immune system responded to the original glycoprotein?
Answer:
It depends on your data, BUT read explanation
Explanation:
There are two ways to see this question and both are related to the fact that there is a parasite that could change surface glycoproteins at its will. Now, the question is when, and that when is once the host immune system attack it. If you perform an experiment where you have surface glycoproteins of the parasite without any disturb, a situation where the parasite has to respond and a control for this situation ( in this case an attack of the immune system), and the surface glycoproteins after the parasite deals with the situation you can infer some things.
First, if you compare the second surface glycoproteins in both experiments (with immune system attack and with control situation), and you see they are very different yo could say the immune system could have some influence on surface glycoproteins.
Now, you cannot infer completely, you have to see if there is a difference between the initial state of the surface glycoproteins and the final state of them after the immune system attack. There you can see if there is any difference on surface glycoproteins.
BUT you have to see if the comparison between the initial state of the surface glycoproteins and the final state of them after the control situation also changes and in what matter to see if is really the immune system the only one who affects surface glycoproteins.
