Chemistry is closely related to life, and there is a lot of chemistry knowledge in the kitchen: 1 T

(1) Vegetables are rich in vitamins, milk is rich in protein, and rice is rich in sugar;

2) The basic components of the constituent substances are elements, and the "calcium" in calcium-fortified milk refers to the elements, and calcium deficiency will cause osteoporosis;

3) Plastic cling film is a kind of plastic, not fiber, rubber gloves are made of synthetic rubber, not fiber, cotton apron is made of cotton fiber, and cotton fiber is a natural fiber

4) There is an emulsifier in the detergent, which can turn large oil droplets into countless small soup droplets, that is, emulsification, so cleaning the oil stains on the tableware with detergent is to use the emulsification function;

So the answer is: (1) A;

2) elemental, osteoporosis;

3）C；(4) Emulsification

(1) Vegetables are rich in vitamins, milk is rich in protein, and rice is rich in sugars, so choose: A;

2) The basic components of the constituent substances are elements, and the "calcium" in calcium-fortified milk refers to the elements, and calcium deficiency will cause osteoporosis;

3) Plastic cling film is a kind of plastic, rubber gloves are made of synthetic rubber, and cotton aprons are made of cotton fibers, so the main materials used belong to synthetic rubber: B

So the answer is: (1) A;

2) elemental, osteoporosis;

3）B．
