With which part or parts of the heart do you think sympathetic and parasympathetic neurons form synapses? explain your reasoning
Softa [21]

The autonomic nervous system is the one that pertains to sympathetic vs parasympathetic. The autonomic nervous system has three divisions: the enteric nervous system, the sympathetic nervous system, and the parasympathetic nervous system.

Sympathetic is the nervous system responsible for your “fight or flight” responses in times of emergencies. It controls the body’s responses to stress, injuries, or perceived threats.

Parasympathetic is the nervous system responsible for your “rest and digest” responses in times of non-emergencies. It controls the body’s responses at rest and helps your body regulate its normal daily organ functions.

One way to remember how to distinguish between the two is to associate the beginning letters of the words with their corresponding attributes.

The sympathetic nervous system kicks in during times of stress, and the parasympathetic nervous system kicks in during times of peace.

Of course, there is much more to both nervous systems than that so let’s look a little bit closer at both.

Lerok [7]

Answer:

Phenotype.

Explanation:

Genotype may be defined as the genetic constituent of the organism. Phenotype is the physical appearance of the organism that can be modified by the organism's genotype.

The tall pea plant (TT) and (Tt) constitute the same phenotype as both the genotypes are responsible for the appearance of the tall height of the plants. The phenotype of the plant is controlled by its genotype.

Thus, the correct answer is option (B).

In one generation, the frequency of the A allele is 70 percent and the frequency of the a allele is 30 percent. What are the cha
babunello [35]
9%

Why?
The frequency for allele a is 30% or 0.3. Let's call this frequency p.
p^2 would then represent the frequency of genotype aa (this is is derived from the formula p^2+2pq+q^2=1 where p and q represent alleles a and A respectively. So p^2=aa, pq=Aa and q^2=AA)
0.3^2=0.09 or 9%
