Answer: very fast environmental changes that affect organisms quickly
Explanation:
Genetic disorders are caused by mutations in genes. These genes consist of DNA and are inherited by the organism by its parents. Genes code for specific amino acids, and they are so complex that we still do not completely comprehend the function of every gene in the human body so we cannot remove them in order to fix a disease. Moreover, every cell in an organism's body has the same genome (except the gametes) so it is not possible to delete the faulty gene from the cells.

Answer:
A-T and C-G are complements so when there is an A in the nucleotide its complementary nucleotide will be a T, vice versa. This is the same with C-G as well.
Answer:
<h2>D. Radioactive nitrogen in the DNA of the bacterial cells is present in one strand of the DNA of all of the cells.</h2>
Explanation:
As given here,
The nitrogenous base of DNA is radio active labeled, and is grown in normal unlabeled medium.
As we know that DNA replication occurs in semi-conservative way, so after one round of replication, one parental strand would be radio active and other newly synthesized strand would be unlabeled.
So here, after one round of replication, one strand of all the newly synthesized DNA would be radio active and other strand would be normal.
