Answer:
Rate = 2 cm/year
Explanation:
It is given that, a plate moves 200m in 10,000 years. We need to find its rate in cm/year.
We know that, 1 m = 100 cm
200 m = 200 × 100 cm
= 20000 cm
Its rate is given by :

So, the plate is moving at a rate of 2 cm/year.
Answer:
A balance of bodily fluids will prevent the development of diseases, the deterioration of body organs, and death of animals.
Explanation:
Water, blood, saliva, sweat and other body fluids should be kept constant and balanced through homeostasis because the sharp rise and fall of these fluids will prevent the organs of the body from operating optimally and this can lead to the development of diseases and consequent death. For example, water is a vital fluid. Too much of water in the system can lead to diseases like Edema where the legs begins to swell because there is no way of letting out body fluids from the body.
Too little water in the body can lead to dehydration and the increase in blood pressure because of the excessive concentration of solutes. The digestive and urinary systems have mechanisms to keep this fluid under control.
