a)
To determine:
The hormone produced by a woman who is breastfeeding.
Concept introduction:
Hormones are synthesized by endocrine gland, these are chemical substances which are carried by blood to target tissue. In target tissue hormones alters the function and structure.
b)
To determine:

Concept introduction:
Hormones are synthesized by endocrine gland, these are chemical substances which are carried by blood to target tissue. In target tissue hormones alters the function and structure.
c)
To determine:
The hormone which is responsible for decrease in blood sugar level.
Concept introduction:
Hormones are synthesized by endocrine gland, these are chemical substances which are carried by blood to target tissue. In target tissue hormones alters the function and structure.
