Question

Which of the following are not known to be present in human skin?
a. thermoreceptors
b. electromagnetic receptors
c. pressure receptors
d. pain receptors

Accepted Answer

Okay everyone. Let's take a look at this practice problem. We have sharks use their blank to detect prey hidden in the sand. In order to answer this question, let's recall how sharks detect their prey, recall that sharks use electrochemical signaling to detect weak electric signals that are produced when their prey have even the smallest muscle contractions. Also recall that organisms usually detect changes in their bodies and environments through receptors. So our answer should be a type of receptor that a shark can use to find hidden prey knowing this. Let's take a look at some of our answer choices. We have a no C sectors, no see sectors respond to potential damage to the body. Sharks won't find their prey by detecting damage so we can eliminate option A. Then we have be appropriate receptors. These receptors perceive movement and position changes. If the prey is hiding in the sand they won't be moving. They'll want to stay as still as possible to not be detected. And therefore sharks wouldn't find appropriate receptors helpful in finding their prey. B. Is wrong. Then we have see electro receptors. These receptors detect electrical fields which is part of electrochemical signaling. Sharks actually have electro receptors all over their head and snout. And so therefore C. Is our correct answer. And we can automatically eliminate D. All of the above. Since both A. And B. Are wrong. So to recap sharks use their electoral receptors to detect prey hidden in the sand. I hope you found this helpful and I'll see you soon for the next practice problem
