Match the following terms and definitions. 1. an electrical nerve impulse sent by nerve fibers to the central nervous system for
vladimir1956 [14]

Answer:

1. an electrical nerve impulse sent by nerve fibers to the central nervous system for interpretation. <u>Action potential. </u>

2. neurons that detect chemicals such as those found in food. <u>Chemoreceptors. </u>

3. type of eyes many arthropods have; eyes that protrude outward and consist of many lenses. <u>Compound eyes. </u>

4. the structure that gives the response to an environmental change.<u> Effector</u>

5. neurons that detect electrical fields. <u>Electroreceptors. </u>

6. secretion of hormones into the blood stream to affect distant processes. <u>Endocrine.</u>

Explanation:  

An action potential is a change in the internal charge of a cell due to depolarization. These changes allow the transmission of a message from any part of the body to the central nervous system. The central nervous system will interpret the message and will give a response.

There are different types of receptors in our bodies. Chemoreceptors are the ones that detect chemicals and produce an action potential or a neurotransmitter. These receptors respond to chemicals. Another type of receptor is the electroreceptors. They detect electrical fields and are only on the skin of aquatic animals.

Compound eyes have a large number of ommatidia. As a result, the anthropods with this type of eyes have a large view angle. In other words, every ommatidium sees an image, and the final product is a combination of all of them.

The effector is the structure that gives an answer once an affector has sent the message to the nervous system that there was a change in the environment.

There are different kinds of secretions, autocrine, paracrine, and endocrine. In the endocrine secretion, the gland secrets hormones into the bloodstream so that they can travel long distances up to their target cell, which is far from the gland.

One unit of alcohol contains 8 grams of alcohol. calculate the risk of developing liver cancer for someone who consumes 4 units
Kryger [21]

The risk of developing liver cancer for someone who consumes 4 units of alcohol a day is twice as high as normal (hepatocellular carcinoma and intrahepatic cholangiocarcinoma).

<h3>What does alcohol do to the liver?</h3>

Alters the production of enzymes, changing the rate of metabolism of the alcohol consumed, causing chronic inflammation, alcoholic hepatitis and cirrhosis.  Irritates the mucous membranes of the stomach and esophagus, causing esophagitis, gastritis and diarrhea.

With this information, we can conclude that The risk of developing liver cancer for someone who consumes 4 units of alcohol a day is twice as high as normal (hepatocellular carcinoma and intrahepatic cholangiocarcinoma).
