Answer:
Explanation:
The structure of a cell membrane is the outer layer of the cell and it contain various cell organelles which are present in both animal and plant cell. It's act as a barrier between the outside environment and cellular content of the cell. It comprises of phospholipid bilayer and integral protein which allow molecules to pass through the membrane and it limits the movement of molecules in the membrane because of it's hydrophobic interior which make the passage of molecules to be selectively permeable.

Answer:
D) All of the above are true.
Explanation:
Wetlands are the regions of land which are covered by water. The water can be fresh water, Saltish water or between these two. Low-lying areas of rivers or oceans, ponds, lakes and marshes, all fall under wetlands.
- Wetlands are extremely important for the life on earth because of immense number of services they provide to humans, wildlife and fish. They are more productive region than coral reefs and rain forests.
- They have an important role in protecting the shores from the strong action of waves that can cause floods. They also help in trapping sediments and thus lowering the losses due to soil erosion. This makes option A true.
- They provide habitat and food source to wide array of organisms such as fish and wildlife therefore option B is also true.
- They also help in the controlling of pollution because they clean or filter sediment from runoff water which ultimately helps in preventing mud clogging in water reservoirs such as lakes. Therefore, they have a cleansing or filtration action and this makes option C true.
Hence, D is the best option.
