Answer:

C. Carbon

Explanation:

The central atom in an amino acid that all the groups connect to is a carbon atom.

Amino acids are monomeric units of proteins. They are bifunctional in that they have an amino group and a carboxyl group. These groups are attached to a carbon atom, α-carbon, in a molecule.

This is common to all amino-acids.

Kruka [31]
<h3><u>Answer;</u></h3>
  • Businesses make more products.
  • Consumers spend more money.
  • Producers earn more revenue.

<u>Explanation;</u>

  • <em><u>Economic growth refers to the upward trend in the economy of a country or a state. It is the increase in the country's produce, that is goods and services over a period of time.</u></em>
  • <em><u>Economic growth is marked by the creation of more profit for business, thus the price of stock or goods increases. As a result the rate of employment increases as the companies have more capital to invest and employ more people.</u></em>

Describe the effects of NE and Ach on contractile force that you observed today. Given your knowledge of sympathetic and parasym
Afina-wow [57]

Answer:

The answer is Norepinephrine.

Explanation:

Acetylcholine (Ach) and Norepinephrine (NE) are both chemical substances (neurotransmitters) released primarily by nerve cells and they affect different parts and systems of the body. Acetylcholine mostly targets the muscles and the brain and it is a part of the parasymphatetic nervous system whereas norepinephrine targets the whole body and has an effect that leads to the contraction of muscles and the increase of the heart rate. Norepinephrine is a part of the symphatetic nervous system.

Since the symphatetic nervous system is responsible for the crucial "fight-or-flight" response of our body, it has a more dramatic effect on the muscle contraction. Norepinephrine, being a part of the symphatetic nervous system, should result in a more drastic change in contractile force.

I hope this answer helps.
