Answer:
Both natural selection and genetic drift are mechanisms for evolution (they both change allele frequencies over time). The key distinction is that in genetic drift allele frequencies change by chance, whereas in natural selection allele frequencies change by differential reproductive success.
Even though conditions in the external environment may vary widely, most organisms must keep internal conditions such as temperature and water content fairly constant to survive.
<h3>What is homeostasis?</h3>
The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose. If these values get too high or low, you can end up getting very sick.
<h3>Homeostasis features:</h3>
- Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment.
- Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.
- In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

<h2>QUESTION:</h2>
what’s the difference between convergent boundaries and the subduction zone
<h2>
ANSWER: </h2>
If two tectonic plates collide more or less head-on they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, which is known as subduction.

The answer to the above question is alleles.
<h3>What are Alleles?</h3>
The two nucleic acids in living things that are employed for conveying and storing genetic information are RNA and DNA. The genetic material in living things is called deoxyribonucleic acid (DNA), and it contains sections coding for beneficial proteins and products as well as carrying genetic information from one generation to the next. These chunks are referred to as genes.
However, genes also have a different form that is in charge of the genetic diversity in the qualities they are coding for. Allele refers to a gene's alternative or variant version. In a diploid creature like the human, each trait is encoded by genes that include contrasting pairs of alleles, allowing variation for that specific trait, i.e. two alleles for each gene. For instance, a gene with two alleles that codes for one of the human height traits includes the short variety (t) and the tall variety (T).
