I believe the answer is Exercised-induced bronchospasm

Exercised-induced bronchospasm  or exercise-induced asthma is a bronchospasm that caused by exercise. Bronchospasm means that the bronchus is narrowing, makes the air become harder to move through it. This makes the person hard to breathe and coughing. Wheezing sound might be heard. Exercising in cold weather have a higher risk to induce this condition.

anygoal [31]

ANSWER:  B, killifish

REASONING: A secondary consumer consumes animals that eat only plants.  Larvae and copepods do not fit these descriptions, because they do not eat animals.  Snapper do eat animals, so do not fit the description either.  Killifish eat small animals that do eat plants.

If thymidine dimers created by UV irradiation persist until DNA replication, DNA polymerase is likely to make a mistake reading
marishachu [46]

Answer:

Thymidine dimers is likely to be repair as soon as it is originated but if left unrepaired then it causes  frame shift mutations.

Explanation:

In case of Bacterium if UV irradiation induces covalent linkage of two thymidine present adjacently to each other or on a single strand to make thymidine dimers.

These either excised via DNA repair enzyme like Endonuclease V and the proof reading activity of DNA polymerase I enzyme help in incorporation of nucleotide by taking the unmutated original strand as a template.

These dimers if not excised before second round of replication than the sequence of newly synthesized strand will be altered. As DNA polymerase III enzyme read thymidine dimers as single thymidine nucleotide and incorporate only 1 adenine in the newly synthesizing complementary strand which results in frame shift mutations

It is the mutation in which reading frame of codons is shifted or altered due to deletion or addition of a single nucleotide.

How does waste move from kidneys to the bladder in the human excretory system?
Salsk061 [2.6K]

The kidneys filter the blood to remove wastes and produce urine. The ureters, urinary bladder, and urethra together form the urinary tract, which acts as a plumbing system to drain urine from the kidneys, store it, and then release it during urination.
