The predator gets the energy it needs to survive.
Answer:Option C
Explanation: The predators are the animal (carnivores) that feed on the other smaller animals for their energy need. The animals they feed on provide energy for their survival.
The predators are generally carnivore animals that eat animals as their soul source of energy to perform the vital functions such as running, walking, eating and metabolism inside the body.
So, predation helps to gain energy from the prey for survival.
What stimulates the secondary oocyte to complete meiosis II?When a sperm cell penetrates the oocyte membraneOvulationA surge of luteinizing hormone (LH)Estrogen production that occurs between puberty and menopause
The correct answer is: When a sperm cell penetrates the oocyte membrane
The oocyte (is arrested at an early stage of the first meiotic division as a primary oocyte. During each menstrual cycle, one the day before ovulation gonadotropin hormone (luteinizing hormone) stimulates completion of meiosis 1. After the meiosis 1, 2 haploid daughter cells are formed: one becomes the secondary oocyte the other forms the first polar body. Newly formed secondary oocyte starts meiosis 2 which arrests at metaphase which will continue after the fertilization.
The completion of meiosis II in the secondary oocyte is stimulated when a sperm cell penetrates the oocyte membrane.
Explanation:The correct answer is when a sperm cell penetrates the oocyte membrane as this event triggers the completion of meiosis II in the secondary oocyte. Meiosis II is the second division in the maturation process of oocytes (egg cells) and is necessary for the formation of a mature egg.
When a sperm cell penetrates the oocyte membrane during fertilization, it triggers a series of biochemical changes in the oocyte, leading to the resumption and completion of meiosis II. This process results in the formation of a mature egg (ovum) with a haploid number of chromosomes, ready for fertilization and embryonic development.
The surge of luteinizing hormone (LH) and estrogen production regulate the ovulation process, but they do not stimulate the completion of meiosis II in the secondary oocyte.

Yes, Protozoa and Prions require a host cell for reproduction.
Can you inherit physical traits that your parents acquired during their lifetime? can you inherit physical traits that your parents acquired during their lifetime? yes no only if it improves survivability only if it improves reproductive success
yes we can inherit the physical traits. like the son of hunter would probably a good hunter, if he his provided with the situations correctly. similarly a daughter of a singer will become a singer too because she will a good voice. it is the survivalist approach as the people tend to follow the same pattern which their forefathers had.
Final answer:
Physical traits acquired by parents during their lifetime, such as muscle built from exercise, are generally not inheritable, as inheritance is determined by genetic traits which are part of an organism's DNA, not acquired characteristics.
Explanation:
Generally, you cannot inherit physical traits that your parents acquired during their lifetime. The reason behind this is that natural selection and other evolutionary forces act on heritable traits that are part of an organism's genetic code, not on characteristics acquired during an individual's lifetime. For instance, if a person builds muscle strength through exercise, this acquired muscular physique is not directly passed to their offspring. However, if a trait, such as the genetic propensity to build muscle efficiently, exists, then that can be inherited. Genetic diversity plays a critical role in evolution, allowing for the propagation of beneficial alleles that aid survival and reproductive success.
Inheritance efficiency is also a crucial factor in reproduction. While an individual may display certain survival characteristics, these are only passed on if they are coded in the genes. An acquired characteristic like improved muscle due to workout does not change the individual's genetic code, thus cannot be passed on directly to the offspring. Consequently, the idea of inheritance of acquired characteristics is not supported by current genetic understanding.

Scientists are researching a large family, many of whose members have Jackson-Weiss Syndrome, a disease that causes bone problems. The scientists noticed that every person with Jackson-Weiss Syndrome had a parent who also had the disease. What is the most likely conclusion that can be made about Jackson-Weiss Syndrome? A. It is not a genetic disease. B. It is a genetic disease caused by a recessive allele. C. It is a genetic disease caused by a dominant allele D. It is a genetic disease caused by a mutation in the child's DNA.
The right answer is C.
A genetic disease is called autosomal dominant transmission when :
* The morbid allele ("sick" version, mutated of the gene in question) is on a non-sexual chromosome (neither X nor Y).
* The presence of a single morbid allele is sufficient for the disease to express itself.
The morbid allele is transmitted by either the father or the mother (or both, if they have the same inherited autosomal dominant genetic disease). Anyone with one of their affected parents is affected.
Jackson-Weiss syndrome is indeed an autosomal dominant disease characterized by a malformation of the feet, craniosynostosis of varying degrees, facial abnormalities, enlargement of the big toes and normal hands.

Answer:
C) protein possesses a signal for localization within the Golgi apparatus.
Explanation:
Protein targeting or sorting is a process by which synthesized proteins are transported to their appropriate localizations in the cell or outside it. Proteins can be targeted to the inner space of an organelle (such as Golgi apparatus or endoplasmic reticulum) or its membrane, plasma membrane, or to exterior of the cell via secretion.
Usually, protein contains signal sequence on the N terminus that is involved in destination targeting.

Heterozygote advantage should be most closely linked to which of the following?
A) sexual selectionB) stabilizing selectionC) random selectionD) directional selectionE) disruptive selection
The correct answer is: B) stabilizing selection
Stabilizing selection is a type of natural selection in which the population mean (non-extreme trait value) is favored over extreme values. It favors the intermediate variants such as heterozygous phenotype (more than both homozygous). This is the most common type of selection, because most traits change little over time (not by favoring extreme traits).
Heterozygote advantage, a circumstance where heterozygous individuals have a higher fitness level than homozygous individuals, is most closely linked to stabilizing selection. This selection favors average phenotypes and works against extreme variations, thus reducing genetic diversity. Hence the correct answer is option B)stabilizing selection
Explanation:
The term Heterozygote Advantage refers to a circumstance in which heterozygous individuals (with two different alleles for a particular gene) have a higher fitness level than homozygous individuals (with two identical alleles). It's most closely linked to stabilizing selection (option B).
Stabilizing selection is a selective force that favors average phenotypes and works against extreme variations. In other words, it tends to reduce genetic diversity over time, which is why it is often associated with heterozygote advantage.
For example, with sickle cell anemia, individuals who are heterozygous for the sickle cell trait are less prone to malaria, giving them a higher survival rate in areas where the disease is prevalent. This is an example of heterozygote advantage and stabilizing selection at work.

A sodium atom can react with a chlorine atom and form an ionic bond. Which statement related to their ionic bond must be true?
*Both of the atoms share their electrons.
*Sodium and chlorine bond to form very large structures.
*The bond that is formed is the strongest type of chemical bond.
*One of the atoms donates an electron to the other atom.
One of the atoms donates an electron to the other atom
Answer: Option (d) is the correct answer.
Explanation:
An atom that donates an electron to another atom will lead to the formation of a bond known as ionic bond.
For example, atomic number of sodium is 11 with electronic distribution 2, 8, 1. Atomic number of chlorine is 17 with electronic distribution 2, 8, 7.
So, in order to stabilize both sodium and chlorine, sodium will donate its valence electron to the chlorine atom. This will form an ionic bond between sodium and chlorine.
Thus, we can conclude that the statement one of the atoms donates an electron to the other atom, must be true.

c. The 3’ end
d. Variable loop
The correct option is c.
The 3' end of a tRNA molecule binds to amino acids during protein synthesis. Specifically, the CCA tail at this 3' end directly binds the amino acids.
Explanation:The region of a tRNA molecule that binds to amino acids is the 3′ end. tRNA, which stands for transfer RNA, is crucial for protein synthesis in the cell. The amino acids are attached to the 3′ end of the tRNA molecule. While the anticodon loop, codon loop, and the variable loop are all important aspects of the tRNA structure, it's the 3' end, more specifically the CCA tail at this part, that directly binds to the amino acids during translation.

negative feedback
Answer:
negative feedback
Explanation:
Insulin reduces blood sugars when the levels are high in the blood. The hormone is produced by the pancreas and binds on receptors of cells. This initiates cell signaling mechanisms that signal the cell absorb sugars. When the blood sugars get back to normal, insulin production is reduced.
Answer:
Negative Feedback
Explanation:
The production of hormone named insulin directly into the blood reduces the level of glucose in blood.
This is done when the body senses that there is an excess of glucose in the blood. This is a an example of negative feedback, as insulin lowers the level of blood glucose and store sugar away from muscle and fat.
It helps the other tissues of the body to work efficiently with the help of energy in the form of glucose.

The alimentary canal is the tubular passage by which food enters the body and through which food residue is eliminated. The anus, large intestine, small intestine, stomach, esophagus and mouth are all parts of the alimentary canal. The four basic tunics (layers) that constitute the walls of the alimentary canal are the mucosa, submucosa, musclaris externa, and serosa. A specific type of tissue that plays an important role in the breakdown of food can be found in each of the layers.
Crinoids, also known as sea lilies, appear to be sea plants but are not plants at all. Crinoids are an echinoderm species which uses anchoring structures called holdfasts to attach themselves to the sea floor. Crinoids were most abundant in Pennsylvania during the Mississippian Period, which ranged from 375 to 320 million years ago. Fossils of the crinoids shows that during most of this time Pennsylvania was ________ that provided favorable conditions for crinoid growth
The correct answer is - under water.
During the Mississippian Period, the climate on the Earth, as well as the shape of the continents and the oceans was not as it is nowadays, in fact it was much different, unrecognizable by their shapes in the present.
Pennsylvania was not part of the land in this period, but instead it was part of the ocean, thus it was under water. Since it was close to the coastline, it was very rich in life, organisms of all types lived in it. One of those organisms that thrived were the sea lilies. They had perfect conditions, so they were one of the most common organisms in this area in the Mississippian Period, thus there's lot of fossil remains from them from this geological period.
Pennsylvania was covered by a shallow sea during the Mississippian Period, which provided favorable conditions for crinoid growth. Crinoids are not plants but echinoderm species that appeared like sea plants. They use holdfasts to anchor themselves to the sea floor.

Which of the following options best depicts the flow of information when a gene directs the synthesis of a cellular component?
A) RNA → DNA → RNA → protein
B) DNA → RNA → protein
C) protein → RNA → DNA
D) DNA → tRNA → mRNA → protein
Answer:
B) DNA - RNA - protein
Explanation:
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product, usually protein. Gene expression include steps such as
• transcription – part of DNA is copied into mRNA via an enzyme RNA polymerase
• RNA splicing – formed mRNA during transcription is not mature so it need to be proceed (e.g. excision of introns). Mature mRNA are then exported from nucleus to cytoplasm
• Translation – mRNA serves as information that codes for the synthesis of one or more proteins.

Different crops use different nutrients in the soil. If the same crop is planted in a field year after year, soon the nutrients the crop needs will be used up. What measure do many farmers take in order to control this issue?
farming is the archaic method of growing food and planting. this helped the man to shift from hunting to more productive ways of getting food. however growing the same crop over and again in the same land causes lack of cultivation. this is due to the lack of nutrients already used by the crops, such as minerals which include potassium, nitrogen, calcium, and phosphorous lessening of which in the soil causes low yield. so, the method used by the farmers is crop rotation. for example cultivating corn after the wheat.
some other ways include the use of fertilizers which also varies in nature and composition like natural and synthetic fertilizers. thirdly, the innovative and technological advancement also ensure better use crop cultivation.
Answer:
By practicing crop rotation
Explanation:
Crop rotation is an agricultural practice in which farmers carry out recurrent succession of crops on the same piece of land in different growing seasons.
Successive crops in a crop rotation regime have different characteristics based on the part of the soil they utilized for their growth.
For example, a crop that utilize nutrients from the surface of soil (surface feeder) may be planted in a season while another plant that utilizes nutrients from the deeper part of the soil (deep feeder) may be planted in its place the following season.
This practice will give ample time for the surface soil nutrient to be replenished before another surface feeding crop is planted.

The 5′cap on an mRNA is important for which of the processes listed below?
ribosomal interaction
initiation of translation
intron splicing efficiency
initiation of transcription
primer removal
transcription of the mRNA molecule
stability of the mRNA molecule
The correct answers are:
• initiation of translation
During the initiation of translation the small subunit of the ribosome binds to the 5' end of mRNA with the help of initiation factors.
• stability of the mRNA molecule
5’ cap prevents the degradation of mRNA by exonucleases.
• intron splicing efficiency
5’ cap is involved in promotion of 5′ proximal intron excision.
Another function of 5’ cap is the regulation of nuclear export (transport of mRNA from nucleus to cytoplasm).
The 5' cap on mRNA is important for the initiation of translation by helping the mRNA attach to the ribosome and in maintaining the stability of the mRNA molecule, protecting it from degradation.
The 5' cap on an mRNA is a crucial modification that has multiple roles in mRNA processing and translation. Notably, the 5' cap is pivotal for the initiation of translation as it helps in the attachment of mRNA to the ribosome. It also plays a role in ribosomal interaction and significantly aids in the protection and stability of the mRNA molecule within the cytoplasm. While the 5' cap can influence intron splicing efficiency indirectly, its primary functions include protecting the mRNA from degradation and being recognized by factors involved in initiating translation by ribosomes.
Swamp sparrows live in a variety of wetland habitats.

Hello!
Coastal-plain swamp sparrows are gray brown whereas others are rusty brown.
There are a lot of genetic differences between the coastal-plain swamp sparrows and the others.
...
Genetic differences must be the reason of of the difference in color.
The gap is that we do not know whether the difference is caused by internal(i.e. genetics) or external (i.e. climate, food etc.) reasons.
Taking these into consideration
A) weakens the argument, because it clearly states that there is no genetic difference between coastal-plain swamp sparrows and freshwater swamp sparrows that affects plumage color, thus the reason of difference in plumage color should be external (for example food)
E) strengthens the argument, because it shows that under same external conditions(“identical diet and controlled conditions”) the birds grew plumage similar in color to that of their respective parents. This shows that external factors have no affect, thus the reason should be genetic.

Name four types of cutaneous sensory receptors
Cutaneous receptors are:
• Pacinian corpuscles-These are types of mechanoreceptor (response to mechanical stimuli such as pressure or vibration). They are nerve endings in the skin that are sensitive to vibration and pressure
• Merkel's disc-These are types of mechanoreceptors, nerve endings that are sensitive to mechanical pressure, position, and sustained touch (shapes and edges of objects).
• Ruffini's end organ- These are types of mechanoreceptors slowly adapted that detects skin stretch.
• Meissner's corpuscles- These are types of mechanoreceptors, nerve endings responsible for sensitivity to light touch (changes in texture).
Four main types of cutaneous sensory receptors are free nerve endings, Merkel's disks Ruffini endings and Pacinian corpuscles. They respond to stimuli like pain, temperature, light touch, skin stretch joint activities and vibration respectively.
Explanation:The skin has a variety of specialized sensory receptors, each responding to specific types of stimuli. Four main types of these sensory receptors are: 1. Free nerve endings which are most common and sensitive to painful stimuli, hot and cold temperatures, and light touch. 2. Merkel's disks, found mainly in fingertips and lips, they respond to light touch. 3. Ruffini endings which detect skin stretch joint activity and warmth. 4. Pacinian corpuscles that detect transient pressure and high-frequency vibrations.
These touch-related stimuli receptors play a crucial role in our sense of touch, allowing us to interact with and understand our environment. For example if an insect crawls on your skin, the movement of hair follicles triggers the free nerve endings, alerting you of the presence of the insect.
