The genetic factor that assists growth and survival in individual organisms is genetic variation.
What is genetic variation?Different phenotypes can be introduced into an organism by genetic changes that modify gene activity or protein function. If a feature is advantageous and aids an individual's survival and reproduction, the genetic variation is more likely to be passed down to the next, generation, a process known as natural selection.
The founder effect could result in a decrease of genetic variety. This is because, by definition, the founder effect is typically seen to be the cause of essential genetic variety in a specie or a specific location where organisms thrive.
Therefore, genetic diversity is a genetic element that aids in the growth and survival of individual organisms.

Scientists aren't certain whether or not viruses are residing or non-residing. In general, scientists use a listing of standards to decide if something is alive. Let’s have a take a observe a few tendencies of residing matters and spot if viruses additionally have the one's tendencies.
Living matters have cells. Viruses do now no longer have cells. They have a protein coat that protects their genetic cloth (both DNA or RNA). But they do now no longer have a molecular membrane or different organelles (for example, ribosomes or mitochondria) that cells have.Living matters reproduce. In general, cells reproduce by making a replica in their DNA. Unlike cells, viruses do now no longer have the equipment to make a replica in their DNA. But they've discovered different approaches to make new viruses. This is completed through putting virus genetic cloth into a number molecular. This reasons the molecular to make a replica of the virus DNA, making greater viruses.Many scientists argue that despite the fact that viruses can use different cells to breed themselves, viruses are nevertheless now no longer taken into consideration alive beneath neath this category. This is due to the fact viruses do now no longer have the equipment to copy their genetic cloth themselves.More recently, scientists have observed a brand new sort of virus, known as a mimivirus. These viruses do comprise the equipment for making a replica of its DNA. This indicates that positive sorts of viruses may also certainly be residingWhat is a virus?The virus is an infectious agent that transfers viroids into the host body causing disease.

Diatoms, like most phytoplankton, are much more abundant in the photic zone than the aphotic zone. Which two factors found in the photic zone are the most essential for phytoplankton?
a.Sunlight and oxygen
b.Sunlight and carbon dioxide
c.Nutrients and carbon dioxide
d.Nutrients and oxygen
Answer:
B
Explanation:
Its just because it is gang ♀️
Phytoplankton are found in the photic zone mainly because of sunlight and carbon dioxide.
Why are phytoplankton restricted to photic zone?The top layer, that is, nearest to the ocean surface is known as the photic zone, it is also known as the sunlight layer. Phytoplankton are the planktonic aquatic species, they are the shallow water creatures, which are restricted to the photic zone in ocean. This is mainly due to the fact that they are totally dependent upon photosynthesis for their survival.
In order to perform the process of photosynthesis, the autotrophs like phytoplankton needs three major things, that is,
Carbon dioxideWaterSunlightTherefore, mainly to get carbon dioxide and sunlight, these species are confined to photic zone, as when goes deeper in the ocean, the availability of sunlight gets limited and photosynthesis would fail to take place.
Thus, the correct answer is option b, that is, sunlight and carbon dioxide.

Predict the effect of the E2delG mutation on the resulting FGF5-L protein. Justify your prediction. Researchers identify a different mutation in the FGF5 gene that results in the overexpression of FGF5. Predict the most likely effect of this mutation on the ratio of hairs in growth phase to hairs in rest phase compared with the ratio when the normal FGF5 allele is expressed
The most likely effect of FGF5 mutation is an increase on the ratio of hairs in the growth phase to hairs in rest phase compared with the ratio when the normal FGF5 allele. It leads to trichomegaly.
What does FGF5 encode?The FGF5 gene code for glycosaminoglycan binding proteins, which are commonly expressed in the root sheath of the hair follicle.
The maximum FGF5 gene expression occurs in the late anagen step (i.e., when the hair follicle forms a new hair shaft) of the hair cycle.
Mutations of this gene (FGF5) produce trichomegaly, thereby increasing the portion of hair in the anagen phase.

Why does testosterone not affect all cells in the body?.
Answer: Only certain cells have cytoplasmic receptors for testosterone. Which of the following statements describes the function of inositol trisphosphate (IP3) as a second messenger?
Explanation:
The specificity of testosterone's effects on cells is primarily due to the presence or absence of specific receptors for testosterone, known as androgen receptors.
What are androgen receptors?
Androgen receptors are proteins found inside cells that can bind to testosterone and similar androgenic hormones.
These receptors are present in different tissues throughout the body, but their distribution varies.
Some cells and tissues express a high density of androgen receptors, making them more responsive to the effects of testosterone, while others may have lower or no expression of these receptors, rendering them less responsive or unresponsive to testosterone.The cells that are most sensitive to testosterone are those that have a higher expression of androgen receptors. These include cells in the male reproductive organs (such as the testes, prostate, and seminal vesicles), as well as certain cells in other tissues like muscle, bone, and hair follicles.Thus, the existence or lack of particular testosterone receptors, known as androgen receptors, is principally responsible for the specificity of testosterone's effects on cells.

Which evidence supports the hypothesis that four-limbed animals came from fish?.
Answer:
Which evidence supports the hypothesis that four-limbed animals came from fish? -DNA analysis shows that fish are tetrapods' closest relatives. -The fossil record shows more and more tetrapod-like fish before the appearance of tetrapods about 365 million years ago.
Most fish have flat heads. However, it's crucial to remember that the earliest known tetrapods, Acanthostega and Ichthyostega, had flat heads. The discovery of a fish with a flat head was a strong cue that this fossil was a part of the gradual transition from fish to tetrapods.
What evidence supports four-limb animals came from fish?The appearance of tetrapods about 365 million years ago, the fossil record records fish that were similar to tetrapods. Human embryos have gill slits, while fish and animals with four legs have embryos that are comparable to those of fish.
Ancient animal fossils have revealed how prehistoric life emerged from the ocean and made its clumsy initial steps toward the development of four-legged land animals.
Therefore, Fish were the closest relatives of tetrapods, according to DNA study. Before tetrapods appeared about 365 million years ago, the fossil record reveals an increasing number of fish with tetrapod-like characteristics.

Compare energy carriers and final products in terms of glucose.
Photosynthesis:
Cellular respiration:
While in photosynthesis carbon dioxide and water yield glucose and oxygen, through the respiration process glucose and oxygen yield carbon dioxide and water.
Photosynthesis: Glucose is produced as an energy carrier in photosynthesis.
Cellular respiration: Glucose is broken down as an energy source in cellular respiration.
In photosynthesis, plants capture sunlight and convert it into chemical energy in the form of glucose. The process takes place in the chloroplasts of plant cells, where carbon dioxide and water are combined in the presence of sunlight to produce glucose and oxygen. Glucose acts as an energy carrier in the plant, providing the necessary fuel for various cellular processes and growth.
In cellular respiration, glucose is used as a fuel to produce energy in the form of adenosine triphosphate (ATP). The process takes place in the mitochondria of cells, where glucose and oxygen are combined to produce carbon dioxide, water, and ATP. During cellular respiration, the chemical energy stored in glucose is released and used by cells to perform various functions, such as muscle contraction, cell division, and synthesis of molecules.
In summary, glucose plays different roles in photosynthesis and cellular respiration. In photosynthesis, it is produced as an energy carrier, storing the energy from sunlight in chemical form. In cellular respiration, glucose is broken down as an energy source, releasing the stored energy in the form of ATP, which is then used by cells to perform essential functions. These two processes are interconnected in the carbon cycle, where glucose produced in photosynthesis is used as a primary energy source for organisms during cellular respiration, ensuring the flow of energy through ecosystems.
