Answer:
Nucleotides are the subunits of DNA. The four nucleotides are adenine, cytosine, guanine and thymine. Each of the four bases has three components, a phosphate group, a deoxyribose sugar and a nitrogen-containing base.
<span>The answer is b. fast / ionotropic;
slow / metabotropic. There is fast neurotransmission since the ligand – gated ion
channel receptor is directly activated by the neurotransmitter. On the other hand, G – protein coupled
receptor is bound to the neurotransmitter in order to stimulate a chemical
signaling cascade which has a longer pathway, thus, making it slow and
metabotropic.</span>
Answer:
The concentrations of KCl and NaCl will tend to be equilibrated in both sides, until there is no more movement in any direction.
Explanation:
Since this is an artificial membrane, the concentration of both substances in both sides, will tend to be the same, this is just the answer to a physical distribution of the concentration of the substances.
In natural membranes, this is not like this because all the living things need to have a movement of these minerals to activate the electric response, this happened by the action and help of some carriers because is an active process, that means, need energy and some other carriers to move the compounds from one side to another.

The statement that is true about the homologous chromosomes of a pair is that they usually have the same genes at the same relative locations.
<h3>What are homologous chromosomes?</h3>
Homologous chromosomes are two chromosomes that are identical but not similar and contains the same genes.
Homologous chromosomes are usually in pairs that comes from both parents of an organism i.e. one from the mother and the other from the father.
The homologous chromosomes make the somatic cells of an organism diploid (2n) which separate only during the anaphase 1 stage of meiosis.
Therefore, the statement that is true about the homologous chromosomes of a pair is that they usually have the same genes at the same relative locations.
