Answer:
Digestion helps mammals eliminate bodily waste.
Explanation:
Humans are considered mammals and we use digestion to eliminate bodily waste. Digestion has three main functions. First digestion of food, second absorption of nutrients, and third elimination of solid waste. There are two processes that take place Mechanical digestion and chemical digestion. Mechanical digestion is the chewing and breaking down of food into smaller molecules, whereas chemical digestion is the breakdown of the smaller molecules into simpler nutrients that the body can absorb and use.
If there are 4 molecules of glucose, there will be 24 carbon, 48 hydrogen, and 24 oxygen.
Answer:
Explanation:
Energy stored in spring = 1/2 k x²
80 = 1/2 x k .2²
k = 4000 N /m
Required force = k x
= 4000 x .2
=800 N
b )
Additional work done
= difference in stored elastic energy
= 1/2 k ( x₂² - x₁² )
= .5 x 4000 ( .4² - .2² )
= 240 J
