Answer:
The structure of a Neuron: <u>Soma/cell body</u> contains nucleus and organelles; <u>dendrites</u> receives nerve impulses and conducts it towards cell body whereas <u>axon </u>conducts nerve impulses away from the body.
Explanation:
A neuron is the structural and functional unit of the nervous system. A neuron has three main structural components namely, soma, one axon, and many dendrites.
Soma is the metabolic center of the neuron and does not participate in conduction of nerve impulse. Many small extensions arise from the soma and are called dendrites. The function of dendrites is to carry the nerve impulse from axon terminals of the presynaptic neuron towards soma.
One large extension of soma is axon that carries the nerve impulse from soma to the axon terminals.
D. Mass consumption
is the answer
selfish
The id is the chaotic part of the personality. It includes human's basic, instinctual drives.
The ego is the mediator between the id and reality. It
compensates the id's impulsiveness with reality. It delays gratification and
enables the person to function effectively.
The imbalance of these interacting powers will cause a
disruption in the personality.
Answer:
The consumption of a drug that inhibits or block the enzyme primase will have problems for the replication of DNA, since it is not possible to synthesize a new strand without this enzyme.
Explanation:
During DNA replication, the enzyme primase is responsible for synthesizing the primers, RNA fragments necessary for the DNA polymerase III to synthesize the new DNA strand.
If for any reason the action of the primase is blocked, the primer could not be synthesized and the effect of DNA polymerase III would be null, so the new DNA strand could not be synthesized.
In DNA replication, the primase contributes to the formation of small fragments of DNA, by the action of polymerase III, which are called Okazaki fragments. These fragments will require the action of another enzyme, ligase, in order to form a continuous DNA strand.
