I believe the answer will be D.
Adding those organic materials back into the soil helps it become rich in nutrients that have been used in order to grow the plants to begin with.
I hope I was able to help. Best of luck!
Answer: only one amino acid in the sequence changes
Explanation: if you change both sequences given to rna sequences in the first one all the amino acids you get are serine. in the second sequence of you change them to rna then do the chart they all are serine but one which is phenylalaine.

Answer:
25%
Explanation:
This cross is a dihybrid cross involving two genes in the guinea pig. One gene is coding for hair color while the other is coding for hair length.
The allele for black hair (B) is dominant over that of brown hair (b) while the allele for short hair (H) is dominant over that of long hair (h).
In a cross involving the parents with genotypes Bbhh (black long hair) and bbHh (brown short hair), both parents will undergo meiosis to produce gametes as follows:
Bbhh: Bh, Bh, bh, bh
bbHh: bH, bH, bh, bh
Using punnet square (attached picture) for this dihybrid cross, 16 offsprings will be produced. According to the question, an offspring with black and long hair phenotype will either have BBhh or Bbhh genotype.
Note that, in the heterozygous state of a gene, the dominant allele will express itself.
Checking the drawn punnet square attached, one will notice that the four circled offsprings have the above genotypes, hence they are phenotypically black and long haired.
Since there are 16offsprings and only four are black & long haired, we then calculate the percentage by saying:
4/16 × 100 = 25%
Therefore, 25% of the offsprings will be black and long haired.
