Answer:
The answer is option A: True
Explanation:
Exposure to environmental stress or pathogens is the fuel that ensures the fitness as well as the survival of species population. These factors leads to adaptation of the cells of the species to survive.
<span>These
islands have different ecologies and most are not connected to each other by landmass.
Therefore, the organism adapt to each of the different ecologies on their
islands. These populations were physically separated due to lack of connection
to each other and would not breed randomly. They therefore formed different species
by allopatric speciation.</span>
A protein's shape directly affects how well it works. For instance, a protein works as a protective protein or a structural protein if its structure is fibrous, as is the case with proteins like collagen and keratin. The protein becomes denatured and ceases to serve its intended purpose if the structure of the amino acids is altered in any way.
<h3>What are amino acids?</h3>
Organic substances known as amino acids have both functional groups for amino and carboxylic acids. Alpha-amino acids, which make up proteins, are by far the most significant amino acids in nature, despite the fact that there are hundreds of other types. The genetic coding only contains 22 alpha amino acids. An organic compound is an amino acid. Carbon-hydrogen bonds are present in organic compounds. All amino acids share a similar fundamental structure. Each molecule has a core carbon atom that is joined to a hydrogen atom, a basic amino group, a carboxylic acid group, and an R-group, also known as a side-chain group.

Explanation:
Genetic variation is increased by meiosis
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I
