. To function properly, the body maintains a blood pH of 7.4. When too much carbon dioxide is dissolved in your blood, your blood pH drops. Chemoreceptors in the aorta and carotid artery detect the pH change and send nerve impulses to the respiratory control center in the brain to increase the rate of breathing. Faster breathing removes excess carbon dioxide from the blood and blood pH levels return to normal. a. This scenario is an example of positive or negative feedback?
b. The STIMULUS in this scenario is:
c. The RECEPTOR in this scenario is:
d. The EFFECTOR in this scenario is:
e. The RESPONSE in this scenario is:

Scientists studied reproduction in the new zealand mud snail to answer the question, “are there benefits to reproducing sexually or asexually? ” which of these hypotheses would least likely aid the scientists as they worked to answer the question? sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation. asexual reproduction is advantageous over sexual reproduction because it allows the snails to produce more offspring. sexual reproduction is advantageous over asexual reproduction because it allows for snails to have increased genetic variation. asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social
