Answer:
A1.The central incisors and lateral incisors are mostly used for biting and cutting, and canine teeth are mostly used for tearing food.
A2.Platelets are tiny blood cells that help your body form clots to stop bleeding. If one of your blood vessels gets damaged, it sends out signals to the platelets.
A3.Cyclone is the term used for a low-pressure system that strikes the South Pacific and Indian Ocean. The same type of disturbance in the Atlantic and northeast Pacific is called a hurricane while typhoon is the term used in Asia.
A4.The process of sorting the wool according to the length, colour and texture of fibres is called grading. Carding – Before wool can be used for making fabric it is disentangled and cleaned.
A5.The image which can be obtained on a screen is called as a real and inverted image.
A6.Nitrogenous wastes in the body tend to form toxic ammonia, which must be excreted. Mammals such as humans excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste. Uricothelic organisms tend to excrete uric acid waste in the form of a white paste or powder.
