Answer 1

Hint: Hormones are the bio molecule which is secreted by the endocrine glands directly into the bloodstream. They are target specific and only act on target organs. They regulate the functioning and metabolism of our body.

Complete Answer:
Hormone secreting glands are called the endocrine glands. Hormones are the signalling molecule produced by the endocrine glands. They are transported through the circulatory system i.e blood. Hormones are mainly derivatives of steroids and proteins. Hormones are also called as the chemical messengers. Different types of hormones are produced by different endocrine glands like thyroid, adrenal etc. Few examples of hormones are-
Thyroid stimulating hormone- It is produced by pituitary. It directs thyroid to produce thyroxine.
Growth Hormones- it is also known as somatotropin. It regulates growth and reproduction and generation in our body.
Calcitonin- It is secreted by thyroid gland. It regulates the calcium and phosphate levels in the body.
Adrenaline- It is secreted by adrenal gland. It helps the body for fight or fright.

The correct answer is (B). The hormone responsible for the body growth is growth hormone.

Note: Growth is the combined effect of many hormones. But the major role is of somatotropin. Somatotropin or growth hormone is secreted by pituitary. It regulates the growth. It helps in linear growth of the body, increase in muscle mass and decreases body fat.
