Answer:

Mutation, fertilization, meiosis are different mechanisms by which changes can occur in the genome.

Explanation:

There are several process which is responsible for causing change in the genome of the species which results in the evolution of that species. Some of these processes are:

1. Mutation: In mutation, some nucleotide sequences get change and this change can occur due to frameshift, addition, deletion or any other process. This change in nucleotide can be seen in phenotype and helps in the evolution of the species.

2. Fertilization: During fertilization mixing of the genome of two individual takes place which results in producing a genetically distinct offspring which contains variation. So as the offspring is genetically different it can contain new alleles that can help the individual to survive in the changing environment.

Which hormone does the sympathetic nervous system release to increase heart rate.
sertanlavr [38]

The sympathetic nervous system releases hormones known as catecholamines which increase the heart rate.

<h3>What is a heart rate? </h3>

it is the number of contractions of the heart per minute.

<h3>What are catecholamines?</h3>

These are the neurotransmitters that have a catechol and a side chain that is an amine.

<h3>Which catecholamines are released by the sympathetic nervous system?</h3>

Epinephrine and norepinephrine are the catecholamines that are released by the sympathetic nervous system to increase the heart rate.

<h3>Where are these hormones released?</h3>

These hormones are released in the blood.

<h3>How does this hormone increase the heart rate?</h3>
  • "These hormones are released at the neuromuscular junction of the cardiac nerves."
  • "They shorten the repolarization period."
  • This speeds up the rate of depolarization and contraction and thus the heart rate is increased.
