<span>The answer is synapse and dendrite
</span><span>A synapse is a structure that allows a neuron (which is one type of animal cells) to pass an electrical or chemical signal to another neuron. That second neuron will then target a certain cell, causing a stimulus in the cell. This permits a direct contact between the cells.
</span>
<span> Dendrites are extensions of a neuron that recieve the signal and propagate it to the rest of the neuron.</span>

Answer:
B. preservation of advantageous genetic mutations
Explanation:
The process of natural selection involves the preservation of advantageous genetic mutation in a given population.
Natural selection is one of the key factors that ensures the evolution of organisms.
- Desired traits that are able to survive adverse conditions like disease, food shortage, natural disasters are favored by the process of natural selection.
- Traits that also undergo advantageous genetic mutation in order to get a competitive advantage is also accrued to natural selection.
Answer:
To determine the fraction for the inheritance of Red green colorblindness the genotype of their parents must be considered although neither John nor Ann is color blind there is a very high probability that Ann will be a carrier if that is the case the fractions of the daughters of John and Ann that are expected to be carriers of that trait is 50% chance.
Explanation:
A punnet square can be used to determine any possible genotypic combinations in the parents. color blindness is a recessive X-linked trait in which the patient is not able to distinguish, red or green or blue color. The normal gene and its recessive allele are carried by X chromosome in men, this color blindness appears in the presence of a single recessive gene Whereas in women color blindness occur only when both chromosome carry the gene this shows criss cross inheritance
