Answer: The answer is B: rocks breaking.
i just did the quiz and put A but it's incorrect
hope this helps (:
Answer:
The mutations lie at locations where they don't affect protein sequence due to degeneracy of the genetic code.
Explanation:
Genetic code is the set of the triplet codons each of which code for a specific amino acid. The nucleotide sequence of mRNA is read in the form of triplets during the process of protein synthesis and the respective amino acid is added to the growing polypeptide chain. The genetic code is degenerate. This means that more than one triplet code specifies one amino acid and some amino acids are encoded by more than one codon.
For instance, genetic codes CUU, CUC, CUA, CUG specify amino acid "leucine". Therefore, any change in the DNA sequence that replaces one code for the leucine with another would not affect the amino acid composition of the protein. This would result in the synthesis of proteins with the same amino acid sequence from both the wild type and mutated genes.

Answer:
A. Plants will only flower during long day periods when the day length exceeds their necessary photoperiod
Explanation:
Photoperiodism is a phenomenon that refers to the response of an organism to the length of day. This phenomenon causes a physiological change in the organisms involved (plants or animals). However, the best studied example of change caused by photoperiodism is that of FLOWERING IN PLANTS.
Different plants flower at different times in response to the day length. Certain plants called LONG DAY PLANTS e.g. spinach and potato etc only flower when the length of day exceeds their photoperiod (threshold), which is usually 12 hours. These plants require very short periods of darkness to flower.
Hence, according to the question, FLOWERING response in plants is the best explanation to describe photoperiodism.
