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.

<h2>Answer </h2>
DNA are found in the cells of all living organisms
<u>Explanation</u>
DNA is a complex molecule consisting of many components which are passed from parent organisms to their offsprings during the process of reproduction. The DNA contains instruction needed for an organism to develop survive and reproduce. DNA is deoxyribonucleic acid and is contained in your body's cells. From microscopic view they are double, large cable of particles termed as nucleotides. This show the cell what proteins to produce in the living organism. Hence, all living things have DNA within their cells.
potential energy
you have potential energy when you're stopped. you have kinetic energy when you're moving. so as you're going down a hill, kinetic energy is increasing and potential energy is decreasing.
cellular respiration releases the greatest amount of energy or ATP.
Explanation:
In cellular respiration 38 ATPs in the process. 4 molecules of ATP are formed in glycolysis, 32 molecules in Oxidative phosphorylation.
alcoholic fermentation: 2 ATP is formed
lactic acid cycle: 2 ATP is formed
photosynthesis: does not produce ATP instead ATP formed from the glucose formed is used in the process.
Answer:
Haploid organisms develop from unfertilized eggs. Diploid cells have 46 chromosomes in humans. Haploid cells have 23 chromosomes in humans. Diploid cells are important for the growth and development of organisms.
