Answer:
Cytosine: 32%
Adenine: 32%
Thymine: 18%
Explanation:
% purines= % pyrimidines
Therefore, the percent of guanine and adenine should add up to 50%, where the percent of cytosine and thymine should also add up to 50%
Answer:
A variation is different to an adaptation as a variation is a difference or variety inside a species, for example a different breed of dog such as a spaniel is a variety of the dog species, whereas an adaptation is a genetic mutation that has developed in order to help an animal survive, such as giraffes having a long neck. Adaptations continue throughout the species due to natural selection.
Answer:
You are checking your carotid artery
The correct answer is: B) stabilizing selection
Stabilizing selection is a type of natural selection in which the population mean (non-extreme trait value) is favored over extreme values. It favors the intermediate variants such as heterozygous phenotype (more than both homozygous). This is the most common type of selection, because most traits change little over time (not by favoring extreme traits).
A protein.
Proteins are composed of trinucleotides units called codons, each coding for a single amino acid.
