Answer:
template 5'->3"
Explanation:
As we all know, with a linear chromosome, on the lagging strand (template 5'->3') of DNA replication, when the last piece of RNA primer at the 3' end is removed, the DNA cannot be extended and this creates the end replication problem.
As sodium ions diffuse inward, sodium channels open.
Membrane depolarization occurs.
Potassium ions spread outward as potassium channels open.
Membrane repolarization occurs.
<h3>What happens along an axon in the right order ?</h3><h3 />
An action potential, which is a fast change in membrane potential, develops when the membrane potential of a neuron's axon hillock hits threshold. There are three steps to this shifting change in membrane potential. Depolarization occurs first, then repolarization, and then there is a brief phase of hyperpolarization.
- A depolarizing current causes an explosion of electrical activity known as the action potential. This indicates that the resting potential shifts toward 0 mV as a result of some action (a stimulus).

Answer:
B. generating more nerve cells
Explanation:
Mitosis is the process whereby a cell divides into two genetically identical daughter cells. It is way through which living cells reproduce and multiply themselves.
Hence, a nerve cell that do not typically undergo mitosis will be incapable of replicating/multiplying itself, hence, unable to generate more nerve cells.
Answer:
Hunter-gatherer culture is a type of subsistence lifestyle that relies on hunting and fishing animals and foraging for wild vegetation and other nutrients like honey, for food. Until approximately 12,000 years ago, all humans practiced hunting-gathering.
Explanation:
Polycythemia is defined an abnormal increase in the number of circulating red blood cells. It is mainly caused by a cancerous condition known as myeloproliferative disorder or due to a low supply of oxygen to body tissues usually due to living in high altitude areas and the body tries to compensate by producing more red blood cells to increase oxygen carrying capacity of the blood
Normal blood count values in a male adult is 4.7 to 6.1 million cells/mcL, while in a female adult it is 4.2 to 5.4 million cell/mcL.
If this blood cell count is significantly higher then these values, and remains there or continues to rise, over a given period of time, accompanied with some specific symptoms, then polycythemia is suspected.
