Answer: The true statement is that Molybdenum atoms can have between 50 and 58 neutrons

Explanation:

Step by step

I) Recall that Atomic number = Number of protons

So, Molybdenum with atomic number of 42 = 42 Protrons

II) Also, recall that Mass number = Number of protons + number of neutrons;

So, if Molybdenum mass number is 92,

then Neutrons = 92 - 42 = 50

III) If Mass number is 100,

then Neutrons = 100 - 42 = 58

So, Molybdenum atoms can have between 50 and 58 neutrons

Option A is correct because isotopes of Molybdenum can have between 50 and 58 neutrons, calculated by subtracting the constant atomic number from the varying mass numbers. Options B and D are incorrect, and C is misleading.

The atomic number of Molybdenum is 42, which indicates that each atom has 42 protons. Isotopes differ in the number of neutrons they contain, while the number of protons remains constant. For isotopes of Molybdenum with mass numbers ranging from 92-100, we can find the number of neutrons by subtracting the atomic number (protons) from the mass number. The number of neutrons will therefore be 92 - 42 = 50 to 100 - 42 = 58.

Given these calculations, option A) Molybdenum atoms can have between 50 and 58 neutrons is correct. Option B) is incorrect because all isotopes of Molybdenum have 42 protons. Option C) is misleading: while a neutral atom would indeed have the same number of protons and electrons, the phrasing suggests variability in electron count due to isotopes, which is not the case. Option D) is incorrect, as isotopes vary in neutrons, not electrons, when considering neutral atoms.

Answer:

b. complementary proteins

Explanation:

Complementary proteins are proteins that contain all adequate amounts of the essential amino acids when two or more protein sources that are deficient or low in some amino acids are combined together to compensate for the deficiency of the other. The protein sources can be eaten together in a meal or consumed the same day to get a complete protein.

For example, grains are deficient in lysine, while legumes are usually deficient in methionine.  Combination of rice which is a grain, together with beans which is a legume, would give us complementary protein diet, making it a complete protein source with all adequate essential amino acids available.

Two or more plant proteins that are combined to provide all essential amino acids are known as complementary proteins.

When 2 or more plant proteins are combined to compensate for deficiencies in essential amino acid content in each protein, the proteins are called complementary proteins. These proteins, when eaten together or throughout the day, can provide a balance of essential amino acids that the body cannot produce on its own. For example, a grain low in lysine can be complemented by a legume low in methionine, forming a complete protein when consumed together, similar to completing a puzzle with missing pieces. Vegans, who exclusively eat plant-based foods, need to combine different plant proteins to ensure they receive all essential amino acids since individual plant proteins typically do not contain them all.

Iconic memory is to echoic memory as ________. Group of answer choices A. implicit is to explicit

B.auditory is to visual

C.visual is to auditory

D.quick is to slow

Answer:

C. visual is to auditory

Explanation:

Iconic memory is a form of visual sensory memory concerning a visual sense of perception. It component comprises of visual long-term memory and visual short-term memory.

Echoic memory originate from the word echo, which typically implies reflection of sounds. That is to say Echoic memory deals with anything involving auditory channel. Thus, we can therefore conclude that Echoic memory pertains to auditory sensory memory that record ans save information heard in order to be processed via the cochlea to the brain where is interpreted and feedback is given in order to be understood.

Hence, Iconic memory is to echoic memory as visual is to auditory.

Iconic memory is a brief sensory memory for visual stimuli and echoic memory is for auditory stimuli. So, 'Iconic memory is to echoic memory as visual is to auditory'.

The term 'iconic memory' refers to a type of sensory memory that is connected to the visual system and forms an afterimage. It only lasts for a very brief time, about one second. On the other hand, 'echoic memory' is a type of sensory memory related to auditory information held just long enough to be processed. These are components of our short-term sensory memories. So in the context of the question: Iconic memory (visual) is to echoic memory (auditory) as Visual is to Auditory.

Answer:

True

Explanation:

In  phase-contrast objective and a phase contrast optical systems is equipped with Light microscope  .

Phase contrast microscope is used to differentiate unstained structures in a cell  that differ in refractive indices and thickness. Thus it is usefull for examining  living unstained organisms.

Light that passed through materials of different refractive index and/or thickness will undergo a change in Phase. The difference in phase or wave front irregularities cause variation in brightness of the structures.

Hoping this might help!!!

The statement about phase-contrast microscopy utilizing differences in refractive indices for better viewing of living specimens is true. It provides enhanced contrast by amplifying phase differences due to refractive index variations without staining the specimens.

The statement that in phase-contrast microscopy, the differences in refractive indices between organisms and their environments are utilized for better viewing of living specimens is True. The principle of the phase-contrast microscope harks back to the idea of refractive index. It details that cells have a different refractive index than their surroundings, which affects the phase of the light transmitted through them. This difference is subsequently amplified by a phase ring in a special phase objective, allowing the phase differences to be translated into differences in brightness, and thereby enhancing contrast without the need to stain the specimen.

This technology leverages wave interference and differences in phases, resulting in a dark image of the object amidst a bright background. Because of this, it becomes a most cost-effective tool for examining live, unfixed, and unstained specimens such as eukaryotic cells, showcasing organelles, and prokaryotic cells, visualizing endospores.

Answer: Bone marrow aspiration and biopsy

Explanation: Are done to get bone marrow samples for testing. They're usually done together. The samples are usually taken from the back of the pelvic (hip) bone, but sometimes they may be taken from other bones.

For a bone marrow aspiration, you lie on a table (either on your side or on your belly). After cleaning the skin over your hip, the doctor uses a long thin needle to put in a drug that numbs the area and the surface of the bone. This may cause brief stinging or burning. A hollow needle is then put into the bone, and a syringe is used to suck out a small amount (about 1 teaspoon) of the thick, liquid bone marrow. Even with the numbing medicine, most people still have some brief pain when the marrow is removed.

Answer:

Option A, In order for the cycle to continue, oxidized electron carriers must be available.

Explanation:

Options for the given question are -

A) In order for the cycle to continue, oxidized electron carriers must be available.  

B) Without oxidized electron carriers, oxygen will not accept the electrons at the end of the electron transport chain.  

C) Phosphate cannot attach to ADP to form ATP without oxidized electron carriers.  

D) The presence of reduced forms of the electron carriers prevents the formation of ATP.

Solution -

Re-oxidized NADH and FADH2 donate their electron back to the electron transport chain (ETC) to produce oxidized ion NAD and FAD. These oxidized ions are very useful for running the process of glycolysis and citric acid cycle.  

The electrons donated by NADH and FADH2 also assist the kerb’s cycle in driving hydrogen ion and hence produces ATP.  

If the movement of electron through electron transport chain stops, pumping of protons into the matrix through the gradient will also stop and the ETC will come to halt .

Answer:

The unacceptable cell would most likely be detected during GAP1 and removed from the cell cycle.

Explanation:

Doesn't have sufficient mitochondria.

If a muscle cell contains less mitochondria than needed during interphase, it may experience a decrease in energy production and may not function properly. The cell could have reduced muscle contraction ability or undergo apoptosis due to lack of energy. Mitochondrial biogenesis can help increase the number of mitochondria to address this issue.

If a muscle cell contains less mitochondria than needed during interphase of the cell cycle, it would likely experience a decrease in energy production. Mitochondria are responsible for producing ATP, the main energy currency of cells. Without enough mitochondria, the cell may struggle to meet its energy demands and may not function properly.

This could lead to various outcomes depending on the severity of the energy deficiency. The cell may have reduced muscle contraction ability, leading to issues with muscle function. It may also undergo apoptosis (programmed cell death) if it cannot sustain its essential processes due to lack of energy.

To address this issue, the cell may try to increase the number of mitochondria through mitochondrial biogenesis, a process that involves the replication and growth of existing mitochondria. This can happen in response to increased energy demands or as a result of specific stimuli.

Answer:

PCBs are very stable molecules

Explanation:

PCBs are approximately 209 compounds made of chlorine. PCBs are formed  synthetically.These compounds have high chemical and thermal stability so their chemical and biological physical degradation is very slow.

The years that these compounds can last are 2 weeks to 2 years in water, 6 years in the soil, and more than 10 years in fish.

PCBs are still found in the environment because they are extremely stable molecules that do not degrade easily and can bioaccumulate in organisms and soils.

Production of PCBs (polychlorinated biphenyls) was discontinued in 1977, yet they are still found in the environment chiefly because PCBs are very stable molecules. These man-made organic compounds, consisting of carbon, hydrogen, and chlorine atoms, were used in a wide range of industrial and commercial applications due to their non-flammability, chemical stability, high boiling point, and electrical insulating properties. Despite their ban, PCBs persist in the environment because they do not easily break down and can both bioaccumulate in wildlife and be found in soils and sediments, even long after production has ceased.

PCBs' chemical stability means that instead of reacting and breaking down, they remain intact and accumulate over time. This is why higher concentrations can be found in predatory fish, and why they have been observed in remote regions like the Arctic, where they condense onto the soil from the atmosphere. Health effects associated with PCB exposure are numerous and can include complications in physical and neurological development, potential carcinogenesis, and effects on immune, reproductive, nervous, and endocrine systems.

flagella: has runs and tumbles

pili: involved in bacterial conjugation

Explanation:

Flagella can be described as hair-like, long and thin appendages which are used by the bacteria for movement. Some bacteria have only a single flagellum while the others might have many of these. The flagella also help the bacteria to track down food particles.

Pili can be described as external structures of the bacteria that allow the bacteria to attach to different substrates. Pili also help in the transfer of genetic material from one bacteria to the other bacteria.

Flagella are slender, hair-like appendages found on bacteria, and they serve as propellers for bacterial movement.

Pili, on the other hand, are external structures of bacteria that play a crucial role in attaching to various surfaces.

Flagella can be found on a wide range of organisms, including bacteria, archaea, algae, protozoa, and spermatozoa. The number of flagella on a cell can vary from one to many. For example, some bacteria have a single flagellum, while others have hundreds or even thousands of flagella.

Flagella play an important role in the movement of many microorganisms. They also help some organisms to sense their environment and to communicate with each other. For example, some bacteria use their flagella to swim towards food or away from harmful substances. Other bacteria use their flagella to communicate with each other and to coordinate their behavior.

Additionally, pili facilitate the transfer of genetic material between bacterial cells through a process known as bacterial conjugation.

Bacteria may possess either a single flagellum or multiple ones, aiding them in both locomotion and the detection of nutrients.

The independent variable in the clinical trial of Drug R is the dosage, specifically 200 mg. Clinical trials often involve comparing a treatment against a placebo to assess its efficacy.

Explanation:

In the clinical trial of Drug R for the treatment of generalized anxiety disorder (GAD), the independent variable is the dosage of the drug, which in this case is 200 mg of Drug R. An independent variable is the variable that researchers manipulate to see if it causes an effect. In clinical trials, it's common to compare the efficacy of a treatment with a placebo to rule out the placebo effect, as was done in the study by Keller et al. (2001) that compared the antianxiety drug Paxil to a placebo.

Answer:

D. The skin

Explanation:

The skin is usually considered as supply-independent for oxygen delivery. The most affected organs and tissues considered as being supply-dependent for oxygen delivery are heart, brain and lungs. These are the most sensitive to oxygen deprivation, being the brain more than the other organs.

To protect vital organs during times of stress, the body redirects blood away from less critical areas, notably the skin, as it can better tolerate lower blood flow compared to essential organs.

To protect vital organs, the body compensates by directing blood flow away from organs that are more tolerant of low flow. The correct answer to the question is d. the skin. Unlike essential organs such as the heart, lungs, and brain, the skin can tolerate lower blood flow without significant impairment. The cardiovascular system is responsible for the resource allocation of blood flow. During activities like exercise, more blood is directed towards organs that are actively engaged in the task, such as skeletal muscles, the heart, and the lungs, and after eating, more blood goes to the digestive system. In contrast, the skin, along with other less vital body parts, receives less blood during these times. Systemic circulation ensures the continuous flow of blood to and from the heart, with regulatory mechanisms adjusting this flow based on the body's needs and activities.
