<span>Answer: c. release 50-80% of their water back into the ecosystem
Rainforest has a high rate of rain, which gives the plant abundant amount of water. There is no need for the plant to conserve and retain water. it doesn't need the ability to adapt to drought either.
Rainforest has a high precipitation because of the transpiration.

Answers:
It is how oxygen and carbon dioxide travel across the cell membrane
Molecules travel with the concentration gradient
Explanation:
In simple diffusion, molecules move from an area of high concentration to area of low concentration until equilibrium is achieved. This occurs randomly unlike in facilitated diffusion where this flow is regulated through channels by facilitators. Nonetheless, these molecules still travel down the concentration gradient, similar to simple difussion.
Answer: Active transport
Explanation:
In this type of transport, energy is required. This is especially because, in endocytosis and exocytosis, the membrane has to form some structure (some form of a vessicle) to facilitate these transport modes. This requires energy from ATP. More so, usually transport in this case is against concentration gradient.
Answer:
Osmosis.
Explanation:
Osmosis is the movement of water from a lower concentrated solution to a higher concentrated solution through a semi-permeable membrane. In this case, the cell membrane has pores that allow only water molecules to pass through but the solute molecules are too large to pass through. Therefore only water is moving down its concentration gradient.
Answer:
Growing more vegetation
Explanation:
Soil erosion by wind occurs anywhere when vegetation and climatic conditions are conducive. These conditions include presence of very strong winds and when the soil is loose, dry, and is composed of fine granulated particles.
It also occurs when the soil surface is relatively smooth and there is sparse or no vegetative. It can also occur where there are large fields with no windbreak mechanisms in place.
The best way to reduce wind erosion is to keep the wind off the soil surface by covering the soil surface. This involves growing of more vegetation, either cash crops or cover crops which serves to protect the soil and keep the winds higher off the surface.
Also trees can be planted around the farms to serve as wind breaks which breaks or reduces the force of the winds.
Also, soil compaction which is the process of increasing the density of soil by packing the soil particles closer together causing a reduction in the volume of air can help to prevent wind erosion.
From the given options above, the best option would be growing more vegetation.
Practicing crop rotation serves to preserve soil nutrients and prevent diseases.
Decreasing riverbank slopes prevents erosion by water.
Avoiding soil compaction would lead to more erosion by wind.
Answer: D
Explanation: Water's high surface tension is due to the hydrogen bonding in water molecules. Water molecules form these bonds in the liquid as well as deeper in the liquid.
