In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell.——————Neurotransmitters are endogenous chemicals that enable neurotransmission. It is a type of chemical messenger which transmits signals across a chemical synapse, such as a neuromuscular junction, from one neuron (nerve cell) to another "target" neuron, muscle cell, or gland cell.
Answer:
B. cv+cv w+w
Explanation:
Fruit flies have a special nomenclature to write the genotype of individuals.
- If the mutation is recessive, you have to write it with lowercase letter(s).
- If the mutation is dominant, you have to write it with capital letter(s).
- Wild-type alleles are indicated with a superscript plus (+).
In this problem, both crossveinless (cv) and white (w) mutations are recessive.
<u>For that reason, a heterozygous individual's genotype for both genes will be written as:</u>
<h2>
cv⁺ cv w⁺ w</h2>
Answer:
D. to increase their surface area
Explanation:
The usefulness of microvilli to cells that have them is TO INCREASE THEIR SURFACE AREA.
