Answer:
D) the arrangement of the nucleotides within genes
Explanation:
De-oxy ribo nucleic acid that is basically a polymer of nucleotides. Nucleotides are composed of three basic units: a de-oxyribose sugar unit, a phosphate group and nitrogenous bases that can be Adenine, Gunanine, Thymine and Cytosine.Adenine always pairs with Thymine and Guanine always pairs with Cytosine.
This is a universal composition of DNA in each and every living organism. The genes are a segment of DNA that contain specific sequence of nucleotides and encode for a specific trait of organism such as height, weight, eye color etc. The sequence of nucleotides expresses the trait in the form of protein product during the process of Translation. The products of translation are amino acids and every amino acids encode for a specific protein in almost all living organisms.
So, what differs in the specie is the sequence of nucleotides in genes. Infact this is the nucleotide sequence which brings evolution in organism and organisms evolve to form new specie with the passage of time. One major cause of change in nucleotide sequence is mutations due to which the organisms change with time.
Suppose the sequence of nucleotide of specific gene in organism A is
AAGGGGAAATTT
However in other specie organism B of same specie is:
TAGGGGAAATTT
This means only mutation of one base changed the gene in organism B and also its product called protein.

Answer:
First of all, the reverse transcriptase synthesizes viral DNA from viral RNA, and then from newly made complementary DNA strand. The second replication process occurs when host cellular DNA polymerase replicates the integrated viral DNA. ... Therefore, mutation can occur during one or all of these replication steps.
Explanation:
The correct option is (C) The eggs from the female laying 1,000 eggs have larger yolks than the yolks of the eggs from the female laying 100 eggs.
The sequence of survival and reproduction events characteristic for a member of the species is known as the life history of the species (essentially, its lifecycle).
- Natural selection drives the evolution of life cycle patterns, which are a "optimization" of trade-offs between growth, survival, and reproduction.
- The quantity of eggs laid by female fish during reproduction may vary, but it doesn't provide accurate information if the eggs from the female that lays less eggs have more yolk.
- Given that the fitness factor remains the same, the quantity of eggs laid does not necessarily correspond to the amount of yolk in the eggs.
