As high cholesterol diets become more common, individuals with the APOE-42 allele will have a better survival rate, so the allele will increase in frequency.
<h3>What is natural selection?</h3>
Natural selection is the main evolutionary force by which evolution (change) occurs over time.
An adaptive allele is a given gene variant that confers an evolutionary advantage to the individual.
In this case, the APOE-42 allele confers an evolutionary advantage and therefore it will increase its frequency in the population.

Well a mutation is like a change in the DNA and so if there was a mutation in the antártica fish, something in their genes would change. If that mutation has a positive effect on it, then that mutation would be passed down to the generations of fish, helping that fish with its survival or something
To describe the ordered arrangement of atoms, ions or molecules in a crystalline material.
The answer is number 2: Use more efficient irrigation techniques. This is because, right now, water is wasted everywhere by inefficient irrigation; many plants are overwatered. By using more efficient irrigation techniques like drip irrigation, people could save a lot of freshwater.
Answer:
The correct answer is 1377.
Explanation:
Peptides and proteins are made in the process of Translation. For this to happen, a molecule of mRNA containing a nucleotide sequence is read by a structure called ribosome. Each group of three nucleotides from the mRNA form a codon, and each codon has an anticodon in the tRNA molecule that will ultimately code for a specific amino acid (except for stop codons -when they appear in the sequence, translation stops-). <u>Taking all of this into consideration, if 3 nucleotides lead to 1 amino acid, to have a 459-amino acid polypeptide it would require 1377 nucleotides (without counting the 3 nucleotides from the stop codon)</u>.
