Dr. Stevens is examining the DNA sequences of a group of mice. He notices that in one of the mice, one nucleotide has been substituted with another in the part of the DNA sequence that codes for fur color. However, despite the substitution, the mouse still
has the same fur color as the other mice that have the typical DNA sequence.
What best explains why the nucleotide substitution in the mouse does not change its phenotype?
OA. DNA sequences do not determine the color of a mouse's fur.
OB. Substitutions in the nucleotides in the DNA of the mouse can affect its genotype but rarely affect its phenotype.
OC.
The substituted nucleotide produces codons that correspond to the same amino acid that is found in the other mice.
OD.
The mouse has a completely different DNA sequence than the other mice.

The substituted nucleotide produces codons that correspond to the same amino acid that is found in the other mice.

Explanation:

Silent mutations are usually harmless since they code for the same protein

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
