no copied ans

Answer 1

Chromosomes are DNA strands coiled several times around a rigid structure called nucleosome.They contain two non identical arms 'p' and 'q'.

The number of chromosomes are constant for a particular species.Humans possess 23 pairs of chromosomes.

Hormones are chemical messengers that trigger a particular reaction in our body.They are made up of proteins or lipids.

Hormones are highly specific and minute quantity of hormones is more than enough to activate that reaction.

Eg: Growth hormone produced by pitutary gland helps in development of muscles and bones.

Hormones and Chromosomes:

Hormones and chromosomes are not only bases of masculinity and femininity and structural units of heredity,

they play important role in various human behaviors. Endocrine System is a network of glands that produce

and secrete chemical messengers that are called hormones, directly into the blood stream. Theses glands are

controlled by hypothalamus that is important relay station and significant brain structure. Pituitary glands

(also called master glands) stimulate or inhibit secretion of hormones from other glands. Sex and reproduction

hormones are called, Steroid hormones. Reproductive organs ovaries (in females) and testes (in males) are called gonads
