Answer 1

Q. No. 1: How does chemical coordination take place in animals?

 Ans: Chemical coordination takes place in animals with the help of hormones. Hormones are the chemical fluids that are secreted by the glands of the endocrine system. Hormones regulate the overall growth and development of the animals.

Answer 2

In animals, endocrine glands, when stimulated, release chemical substances called hormones. These are directly poured into the blood which circulates them to all the body tissue cells. Body tissue cells have specific molecules (receptors) to identify specific hormones either on their surfaces or inside their cytoplasm. Once the hormone combines with specific receptor present on target cells, it then transmits the information to bring about the effect.
