Thepotemich [5.8K]

The answer is (b.) fertilization

The fertilization is the stage where the egg cell or the so-called ovum fused with the sperm cell which eventually leads the development of the embryo or the zygote. The Embryogenesis starts when the zygote undergoes mitotic divisions or also known cleavage process.

Manny is using a computer model to investigate the effects of substitution mutations. The model presents Manny with a long base
Troyanec [42]

Answer:

The most likely explanation for the truncated polypeptide -due to the substitution of cytosine for adenine- is that mutation introduced a stop codon in the middle of the gene.

Explanation:

A codon consists of three nucleotides -in the RNA chain- whose order determines a specific amino acid. Not all codons code for amino acids, as there are termination codons, also called stop codons, which are UAG, UGA and UAA.

If in Manny's computer model, the substitution of cytosine by adenine produced a termination codon, the synthesis of a peptide is stopped prematurely resulting in a truncated peptide.

Scilla [17]
Overproduction
Most species produce more offspring than can survive.

Competition
Since living space and food are limited, organisms must compete for the necessities.

Variation
Differences between individuals in a population.

Adaptations
Any kind of inherited trait that improves an organism's chances of survival.

Natural selection
The environment selects organisms with optimal traits to be the parents of the next generation.

Speciation
Over many generations, favorable adaptations accumulate and may result in a new species.
