The process of digestion begins in the mouth with the intake of food. The teeth play an important role in masticating (chewing) or physically breaking food into smaller particles. The enzymes present in saliva also begin to chemically break down food.

Answer:
You depend on each other and need the nonliving things in your home, like food, water, air, and furniture. Living things need nonliving things to survive. Without food, water, and air, living things die. Sunlight, shelter, and soil are also important for living things.

Answer:</h3>
The structure of Electrophile (2-methylpropan-2-ylium) is shown in attached picture highlighted by green color.
<h3>Explanation:</h3>
Electrophiles are those species which are electron deficient and loves electron. These species often carry positive charge or contain atoms which have incomplete octet.
Also, we know that Benzene undergo Electrophilic Substitution reactions in which hydrogen atom is replaced by other electrophile. In given statement the electrophile to be reacted with benzene to form tert-Butylbenzene is generated from 2-methylpropene. 2-methylpropene when treated with phosphoric acid adds one proton across the double bond (electrophilic addition reaction) and generate a positively charged tertiary carbocation (stable) (highlighted green) which acts as an electrophile. Further on reaction with benzene this electrophile is substituted with proton and results in the formation of tert-Butylbenzene.
The axle and Wheel are 2 circles, and they rotate together. Force is usually transferred from the axle to the wheel. The mechanical advantage of the wheel and axle is essentially the ratio of the radius of the wheel over the radius of the axle
MA =Radius of wheel
Radius of Axle
Of the above options you've given, the only nuclear reaction is fission.
fermentation is when organic matericals go bad and delope mold for exg,
reduction is when atoms of elements have their oxidation states changed (exg rusting)
deposition is when molecules set out in any sort of solution.
