_________ are chemical signals released by one individual that affect the behavior of another individual.
| a. Hormones | c. Pheromones |
| b. Neurotransmitters | d. Endorphins |
Introduction:
Chemical signaling is an important method of sending signals which are used for various processes within or outside the body. Different processes, which are altered as a result of chemical signaling, are the reproductive system, circulatory system, respiratory system and many more.
Reason for correct answer:
Option c. is given as “pheromones.”
Pheromones are chemical signals that are produced and released by the body in the surrounding environment. These pheromones are signaling molecules which affect the behavior of the other members of a species. Pheromones affect behavior and signal factors such as sexual arousal, danger, communication, and other factors.
Reason for incorrect answer:
Option a. is given as, “hormones.”
Hormones are released inside the body and not outside it. They affect the behavior of an individual. Also, hormones do not influence the behavior of other members of the species...
