Answer:
The body uses osmosis by lowering the water potential near the skin by exerting a small amount of salt inside the sweat glands, this lowers the water potential inside the gland, and this causes water to move into the gland via osmosis as the water potential is higher outside the gland then within it.

Answer:
A growing problem
Yet history is not the only reason why flood-prone locations are overpopulated. For one thing, rising sea levels and a changing climate are putting more cities' residents at risk. And what's more, new homes are still being built in flood-prone areas around the world.

Answer:
phototropism
Explanation:
The student was investigating phototropism.
The student wanted to know the response of the roots to light, that is why he exposed them to light.
Roots naturally exhibit two types of tropisms.
The first is gravitropism whereby they tend to grow downwards.
The second is hydrotropism whereby they grow towards the direction of water.
In the above experiment, no water was provided, the roots grew away from the light source but not specifically downwards.
Well to find the answer for force, the formula is mass X acceleration.
So, 20m/s² X 0.5kg = 10kg-m/s².
But, because we measure force in Newtons, we have to change the units (kg/m/s²) to Newtons.
1N (newton) equals to 1kg-m/s² and because we had 10, your answer is
10N
