The most effective way to prevent DNA mutation from UV radiation is: (C.) Avoid UV radiation by wearing sunscreen.

Mutation is the change in the normal sequence of DNA. The agents that induce these mutations are called mutagens. The mutations can be harmful as they can hamper the normal functioning of the living body. Some mutations however do not cause any significant changes and they are therefore called silent mutations.

Sunscreen is a a cream or liquid applied to the skin that prevents the harmful radiations of the sun to enter the body. They protect from the sun's UV-A and UV-B radiations.

An action potential causes the release of neurotransmitters by:________.
seraphim [82]

Answer:

b) opening calcium pores in the membrane

Explanation:

The opening of calcium  ions channels facilitates the migration of vesicles containing neurotransmitters in the pre-synaptic neurons  to the tip of the post-synaptic membrane. at the <u>neuromuscular  junction </u>These neurotransmitters can either be <u>cholinergic or non-chorlinergic.</u>   <u>At the tip  of the pre-synaptic membranes the vesicles empty their neurotransmitter contents into the synapse.</u>

The neurotransmitters,  diffuse through the neuromuscular junction to bind  with the receptors on the <u>post-synaptic membrane on the post-synaptic neuron.</u> This  stimulates opening of<u> ligand gated sodium ions,</u> and sodium ions  diffuse into the post-synaptic neuronal membrane, to cause <u>depolarization</u>. if the stimulus is  up to the threshold levels   it  generate action potential.

Therefore , more calcium ions channels opening produces; more diffusion of neurotransmitters;leading to opening of more sodium channels for depolarization; and IPSP or EPSP  generation.
