Answer:
B. retain its urine in it’s blood stream
Explanation:
Sharks are cartilaginous fishes that lives in the ocean. Oceans are always salty, hence organisms need to maintain a salt-water balance between their internal and external environment because of osmosis. Sharks are able to maintain this by ensuring that the amount of solutes in their internal environment is as much as that in their external environment.
Sharks retain a chemical contained in urine called UREA in their bloodstream to counter the osmotic effect of the salt concentration in the waters they live. This helps them maintain a concentration balance with their environment.
It will cause vasodilation of blood vessels in the brain.
CO2 is one of the metabolic end products that can alter the
tone of the blood vessels in the brain. High CO2 levels cause vasodilation,
which may cause headache, whereas low CO2 levels cause vasoconstriction, which
may cause lightheadedness. The statements included in the other options are
incorrect effects.

Answer: hello some details relating to your question is missing below is the missing detail
DNA Sequence= 3’ - TACTAGTTGTGCATT - 5’
Complementary Sequence=5`-ATGATCAACACGTAA-3`
Answer : MINT
Explanation:
The protein ( sequence of amino acids ) that resulted from your Translation is MINT
The m-RNA Produced form the information above is:
5`-AUGAUCAACACGUAA-3`
While the Protein Sequence is Met-Ile-Asn-Thr which can be written as MINT
Not very many, as most would get mauled and eaten by bears and other predators
