Introduction:
Hormones are called chemical messengers. With the help of blood, the hormones reach to the organs and the tissue to maintain their function. There are many types of hormones that are secreted in the body to maintain the processes and function. Thyroxine hormone is secreted by thyroid glands. Among these, epinephrine hormone is released by the adrenal gland and it is produced in high amounts during chronic stress, tumors, and obesity. The result of excessive production of epinephrine is sweating, irregular and rapid heartbeat, and anxiety.
Answer to Problem 30A
Correct answer:
The correct answer is option (B) person B.
Explanation of Solution
Explanation/justification for the correct answer:
Option (B) person B. Epinephrine is a hormone that gets released in high amounts during chronic stress and fear. And the person shown in picture B seems frightened. So, the correct answer is option (B).
Explanation for incorrect answer:
Option (A) person A. Epinephrine is not released while a person is sleeping as during sleep the body is at a relaxed position and the person in picture A is sleeping. So, this is an incorrect option.
Option (C) both persons. In the given pictures one person is sleeping and another is in some stress, therefore, seems frightened; therefore person B will have a high level of epinephrine compare to person B. So, this is an incorrect answer.
Option (D) neither person. In the given pictures one person is sleeping and another is in some stress, therefore, seems frightened, hence, person A will produce less amount of epinephrine and person B will produce a high amount. So, this is an incorrect answer.

- There is a species of eagle, which lives in a tropical forest in Brazil. The alula pattern of its wings is determined by a single autosomal gene with four alleles that exhibit an unknown hierarchy of dominance.
