Answer:
Diffusion of solutes in liquids is very important in many industrial processes, especially in such separation operations as
1) liquid–liquid extraction or solvent extraction,
2) gas absorption
3) distillation
4) Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow
5)and lets them get rid of waste products.
Answer: The nervous system of human body is responsible for thermoregulation.
Explanation:
Thermoregulation is the process whereby an organism maintain its internal temperature despite changes in External temperature. The nervous system of human body is responsible for thermo regulation. The nervous system consist of nerves cells and fibres which send nerves impulses to the body parts. It comprises of central nervous system and peripheral nervous system. The centsl nervous system consist of brain and spinal cord while the peripheral nervous system consist of nerves. A part of the brain (central nervous system)called hypothalamus controls thermo regulation. When it senses a change in internal temperature of the body, its send signals to the organs, muscles, glands and nervous system , they respond differently so as to restore the body temperature to its normal one.
