Answer:
The correct answer is - when action potentials trigger the release of neurotransmitters.
Explanation:
Communication between neurons takes place by signaling that can be either chemical signaling or electrical signals. Communication between neurons occurs at very small gaps known as synapses.
These synapses have two specialized cells that help two neurons communicate by one to another to allow for chemical transmission. The chemical that isreleased due to the stimulation of the action potential in order to communicate the neurons are known as neurotransmitters that allow for transmission.
Answer/Explanation:
First, initiator protein unwinds a short stretch of the DNA double helix. <u>The length of the DNA double helix about to be copied must be unwound. </u> In addition, the two strands must be separated, much like the two sides of a zipper, by breaking the weak hydrogen bonds that link the paired bases. Once the DNA strands have been unwound, they must be held apart to expose the bases so that new nucleotide partners can hydrogen-bond to them. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.
None of the above, arteries pump blood away from heart.
Answer:The helix structure Of DNA helps prevent it from been expose and also the sugar and phoshate group that are important components of nucleotides forms a backbone on the helix structure or the polynucleotide this back bone is hydrophobic i.e water loving hence wouldn't allow for penetration for water.
2. Hydrogen bond is formed between this bases to keep them in place.

inferior and superior vena cava, and exhausting oxygen-poor blood from the body into the right atrium. The pulmonary vein discharges oxygen-rich blood, from the lungs into the left atrium.</span>
