Why is it important for the release of acetylcholine to stop and for enzymes to destroy any remaining acetylcholine in the neuromuscular junction? A. calcium would be pumped back into storage and cross-bridges would stop farming.
B. the strength of the muscle would increase.
C. the muscle would not be able to contract.
D. the muscle would continue to contract uncontrollably.

Answer:

Cytochrome C; it provides evidences that there is similarities in the respiratory pathways for producing ATPs by  all living organisms especially mammals.

Explanation:

Cytochrome c is located in the intermembranes of mitochondria, and it functions in the transfer of  of one electron in electron transport chain,(ETC) needed for  generation of proton motive force;  for generation of energy in the synthesis of ATPs by ATPase synthase  during chemiosmosis. Its allows oxdation-reduction by the switching of its iron ii to iron iii. during electron transports.However its iron atoms does not undergo oxidation with  oxygen. This feature makes it stable and  an ideal carrier of electrons.

Its amino acid sequences is very similar in all living organisms especially  between mammals(e.g man and chimpanzees)with little variation in few amino acid residues due to mutation.This similarity in its amino acids sequences in all  living  organism together with small molecular size makes it ideal  molecular evidence  for studying comparative molecular evidence of  evolution.

This is because it can be used  to trace  the pathways of respiration to synthesize energy, and therefore to conclude that  most  organisms share common ancestry, since a very similar protein sequence in  a structure(Cytochrome c) participated in unique ETC mechanisms  in all, needed for energy synthesis .

Antibodies are produced when the body is exposed to antigens.

During an initial encounter with a foreign antigen, the body's immune system namely the adaptive arm of the immune system, produces memory cells, a group of special lymphocytes that retain and store memory of the antigen.

On a second encounter with the same kind of antigen, the immune system "remembers" the antigen and mounts a rapid, specific and vigorous immune response against the antigen. This response includes the production of massive amounts of antibodies very specific to the antigen.

The antibodies effectively neutralize the antigen and facilitate its destruction.

Answer:

C. Antigens

Explanation:

Antibodies a protein formed by immune-responsive cells that is specific for a particular antigen and can bind to it to inactivate or destroy it.

The correct answer is bitter.

People have very strong negative reactions when it comes to a bitter taste. Most of the substances like toxins have bitter taste. The ability of the taste buds to taste the bitter substances shows evolutionary history. The taste has evolved because most of the substances that are harmful to the human beings are bitter in taste. The substances such as alkaloids, drugs, medicines, quinine, caffeine and nicotine have bitter taste. These tastes are not very common to the taste buds so they are detected at very low concentrations.

Answer:

Humans are heavily polluting the waters in many areas with chemicals, medicine (for people), and garbage. A way that the government can help stop this issue is to have groups do routine cleanings of natural bodies of water along with prohibite the use of disposable items in the area like cups and/or bags.
