Answer:

the correct option is A "peptides form crosslinks between polysaccharides"

Explanation:

The bacterial wall of bacteria is made up of a complex peptide that is called peptidoglycan, which in turn is intertwined with polysaccharides and many more structures such as protein, this wall is confined or has the function of being able to protect the osmotic balance of the bacteria so that it does not go into failure and does not lose vitality. If the wall breaks, the bacteria goes into osmotic shock and dies, which is why this was a great discovery, because although it is very difficult to pass through antibiotics or antiseptics, once the porification of this wall is generated, the osmotic balance is lost and bactericidal power is acquired.

Which variable is likely to undergo the largest change in value resulting from a mutation that introduces a new allele into a po
dsp73

Answer:

b. average heterozygosity

Explanation:

From the available options:

a. nucleotide variability

b. average heterozygosity

c. average number of loci

d. geographic variability

Nucleotide variability represents a form of genetic variation that occur as a result of difference in nucleotide sequence of deoxy ribonucleic acid.

The locus is a region on the chromosome where genes are located. Average number of locus thus refers to total number of loci per total number of individuals in a population.

Geographic variability refers to difference in genetic traits across the various geographical distribution of a population.

Average heterozygosity is the percentage or proportion of heterozygous individuals for a trait within a population. It is a common measure of genetic variation in a population.

When a mutation occur within a population and this leads to the introduction of a new allele at a locus for which some individuals within the population are homozygous, it will directly affect the average heterozygosity of the population because more individuals will lose their homozygosity and become heterozygous.

<em>The correct option is b.</em>

It is known as a transgenic organism. This procedure is otherwise called "genetic engineering." Genes of one species can be altered, or qualities can be transplanted starting with one animal types then onto the next. Genetic engineering is made conceivable by recombinant DNA innovation. Living beings that have modified genomes are known as transgenic.
