Dr. stevens is examining the dna sequences of a group of mice. he notices that in one of the mice, one nucleotide pair is substi
serious [3.7K]

Out of the following given choices;

<span>A.      </span>The mouse has a completely different DNA sequence than the other mice.

<span>B.      </span> The substituted nucleotide has the same directions as the original nucleotide.

<span>C.      </span>Substitutions in the nucleotides of a mouse's DNA never affect their phenotypes.

<span>D.      </span>DNA sequences don't determine the color of a mouse's fur.

The answer is B. Most probably, the nucleotide substitution did not translate to a change in the amino acid sequence in the translated protein. As you may be aware, most amino acids are coded by more than one codon. For example, Leucine is coded for by CTT, CTC, CTA, CTG, TTA, TTG. Therefore, a substitution, that causes a change to either one of the sequences will not change the amino acid.

Which labeled placemark in the layers folder represents the stratosphere?
Leya [2.2K]
The atmosphere is divided into different regions, called layers. The layer closest to the surface is known as troposphere, after which comes the stratosphere. The stratosphere begins at an altitude of 10 miles above the surface of the earth and stretches up to 31 miles above the surface of the earth. It is the second layer of the atmosphere (beginning from the surface of the earth) and it is the region which contains ozone, which plays a vital role in stopping ultraviolet radiation from reaching the earth's surface.

Which explanation is most likely the reason for the evolution of a larger brain in humans? The size of the human brain increases
SCORPION-xisa [38]

Across nearly seven million years, the human brain has tripled in size. The most likely the reason for the evolution of a larger brain in humans is that a larger brain allows humans to solve complex problems. Large, complex brains  enable humans to process and store a lot of information and to interact with each other and with their surroundings better. The  brain we now humans have is the largest and most complex of any living primate.
