Answer;
Neutralization of free radicals
Explanation;
-Peroxisomes are small vesicles found around the cell. They have a single membrane that contains digestive enzymes for breaking down toxic materials in the cell. They differ from lysosomes in the type of enzyme they hold. Peroxisomes hold on to enzymes that require oxygen (oxidative enzymes).
-The oxidative enzymes that break down fatty acids and amino acids, resulting in, among other things, the production of the toxic substance, hydrogen peroxide.
In order to support the hypothesis that mutations occur in response to an environmental challenge, the experiment in question would have to show an increase in mutation rates shortly after the environmental challenge was introduced.
When we test a hypothesis, we perform an experiment and gather data over the course of the testing. In order to obtain evidence that supports a hypothesis, we have to ensure that only one variable is changing and be sure to repeat the experiment to confirm the values measured.
Taking this into account, a hypothetical result of the fluctuation test that would support the hypothesis of mutations in reaction to environmental challenges would be to measure a spike in mutation rates in the generation following an environmental challenge, and then continue to do so with future post-challenge generations.

D specialised cells are formed
Answer:
Midocean ridges form at very large cracks in the ocean.
Molten magma fries through the crack and cools to form new land.
New magma from below pushes up, causing the seafloor to spread (divergent boundary).

Olfactics, or your sense of smell, operates subtly but powerfully to influence your reactions to other people regarding environmental stimuli to different factors.
<h3>What is the olfactory epithelium?</h3>
The term olfactory epithelium makes reference to the smell sense, which depends on specialized cell receptors that cover the cells in the airways and help to sense different small in nature as well as to trigger responses depending on these environmental stimuli.
In conclusion, olfactics, or your sense of smell, operates subtly but powerfully to influence your reactions to other people regarding environmental stimuli to different factors.
