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.

True or False: Meiosis halves the chromosome number, whereas mitosis maintains the same chromosome number.
AleksandrR [38]

Answer:

True

Explanation:

Meiosis is the kind of cell division that results in the production of daughter cells with each cell having half number of chromosomes as the parent cell. Meiosis is the cell division employed by reproductive cells to produce gametes/sex cells. Meiosis occurs in two stages i.e. Meiosis I and II. The chromosome number reduces by half in gametes in order to ensure that after fertilization of both male and female gamete, the resulting organism has the correct set of chromosomes. e.g diploid organism produces haploid gametes which fuses to produce a diploid organism again.

Mitosis is another type of cell division that results in identical daughter cells. They are identical in the sense that they possess the same number of chromosomes as the parent cell that divided. For example, a diploid cell undergoes mitosis to produce two diploid daughter cells.
