Question

Give two feature of following:
(i) Tissue that store fat.
(ii) Tissue that stimulate impulses.
(iii) Tissue that control contraction and relaxation of heart.

Answer 1

(1) Tissues That Store Fat- Adipose Tissue. This type of tissues are used for the purpose of storing fat, as reserves. Furthermore, they are used as insulation to trap heat with in the body of organism, like in the instance of polar bears. Another use is to protect the internal organs, from shocks due to movement of the organism.
(2) Neurons are what stimulate impulses, through long Axons, which are extensions which are specialised for conduction. They contain channel proteins, to allow rapid polarization of the axon inside the cell and the outside. Furthermore, the axons are long in nature, to allow the conduction over larger distances, when compared to normal cells.
(3) Tissues that control the contraction and relaxation of heart are known as Smooth muscles, which contract when an impulse travels through them.
