Answer:
B. Carbohydrates provide energy for living things.
Explanation:
<span>These are the nociceptors. These nerves are the slowest to adapt to changes, which is a positive because there is likely no evolutionary advantage to not detecting a painful stimulus. Having receptors that selectively detect pain and nothing else helps an organism to understand what stimuli to avoid.</span>
Answer:
Main Difference – Mutation vs Variation
Mutation and variation are two simultaneous events involved in the process of evolution. The main difference between mutation and variation is that mutation is an alteration in the nucleotide sequence of a gene whereas variation is any difference between individuals of a particular species. Mutations may arise due to environmental factors such as chemicals and UV. Germline mutations are inherited by the offspring. Somatic mutations occur in the ordinary body cells. Variation can occur due to mutations, genetic recombination, gene flow, genetic drift, random mating, random fertilization, and environmental factors. Variation may also cause evolution through natural selection.

the answer is a <u><em>phospholipid bilayer</em></u>
it's called phospholipid because it's made of a group of lipids that has a phosphate group and bilayer because it's made of hydrophilic heads that are exposed to the solution and hydrophobic tails that are directed inwards
