I dont really understand where someone would get this information. was there a document or article you were supposed to read before this if so that would be very helpful.
<h2>
Answer:</h2>
I believe the correct answer is D. React to stimuli from outside the body.
<h2>
Explanation:</h2>
Hormones are types of proteins that produce responses hand in hand with neurons but they are much slower and longer lasting. They can act on the same cells and in that instance they will be called autocrine hormones. Those that act on neighbouring cells are called paracrine hormones while those that act on far away cells are called endocrine hormones.
<h2>Further Explanation:</h2><h3>a. Initiate behavior and reproduction:</h3>
This is a function of hormone(s). Hormones such as testosterone can initiate both behavior of an organism and also stimulate reproduction. Testosterone causes maturation of sex features and sperms in males to initiate reproduction. Other hormones with such functions include: Estrogen and adrenaline.
<h3>b. Coordinate the production and use of energy:</h3>
Some hormones conduct this function by regulation metabolism in the body. These include: Insulin in intake of glucose for energy and glucagon in maintaining blood glucose levels. Corticosterone also responds in stress to maintain energy.
<h3>c. Maintain nutrition and metabolism:</h3>
Nutrition can be maintained by hormones such as ghrelin that stimulates appetite, insulin in intake of glucose, leptin and glucagon.
<h3>d. React to stimuli from outside the body</h3>
This is not a function of a hormone but rather the function of a neuron. Neurons have specific structures called denrites that recieve signals/stimuli from outside the body then convert them to nerve impulses that are transmitted to the brain which produces another impulse to be taken to a specific site to produce a desired response.

Since both aerobic and anaerobic processes can result in the production of CO2, we couldn't be certain that cellular respiration was occurring.
Carbon dioxide:
Carbon dioxide is released during cellular respiration as a waste product. Cells that are capable of photosynthesis can utilize this carbon dioxide to create new carbohydrates. Additionally, oxygen gas is necessary to act as an electron acceptor during the process of cellular respiration.
There are two types of cellular respiration: aerobic (occurring when oxygen is present) and anaerobic (in absence of oxygen).
Now, carbon dioxide is emitted as a byproduct in both types of respiration.
Therefore, determining the rate of aerobic cellular respiration by measuring the amount of carbon dioxide emitted is impossible.
Therefore, to obtain the precise rate, we monitor oxygen rather than carbon dioxide.
Therefore, the correct response is that CO2 is created during both aerobic and anaerobic processes; we were unable to confirm if cellular respiration was occurring.

B.
Humans are also part of ecosystems and if they cease to exist, human well being will be affected.
