A. Selective Permeability
B. Open Bilayer
C. Homeostatic Membrane
D. Temporary Permeability

Answers

The answer is c Homeostatic Membrane

The plasma membrane separates the cell from the outer environment. It only allows the movement of certain molecules through selective permeability. Thus, option A is correct.

What is selective permeability?

Selective permeability is the property that allows the movement and transportation of the molecules inside the cell through active or passive transportation.

It is seen in the plasma or the cell membrane of the cell as it allows only certain specific molecules to enter or leave the cell. It is important for the protection of the cell.

This allows the exchange of the nutrients and waste produced in and out of the cell. The selective permeability is the semi-permeability that is due to the lipid bilayer of the membrane.

Therefore, option A. the cell membranes are selectively permeable.

Which of the following is NOT a source of nitrogen that is available to plants?

Answers

Answer:

I CANT SEE THE FOLLOWING BUT I WILL EXPLAIN.

Explanation:

Plants usually absorb nitrogen from NO3- and NH4+

Nitrogen oxides released into the atmosphere by burning fossil fuels and organic matter is not a source of nitrogen which is available to plants. Thus, the correct option is D.

How does plants take nitrogen?

Plants require nitrogen as it is a macronutrient. The deficiency of this nutrient can cause many diseases. However, plants cannot themselves obtain the nitrogen from air but they rely mainly on the supply of combined nitrogen atom in the form of ammonia molecule, or nitrate molecule, resulting from the nitrogen fixation through free-living bacteria in the soil or the bacteria living symbiotically in the nodules on roots of legumes.

Plants can take nitrogen through absorbing the soil by their roots. Plants cannot get this nitrogen directly from the air. Although, the nitrogen element is abundantly available in air. Nitrogen is unreactive atom, and it cannot be used by the green plants to make proteins. Nitrogen gas needs to be converted into nitrate compounds in the soil through nitrogen-fixing bacteria in soil, root nodules or lightning. Every nitrogen atom is triple-bonded to another nitrogen atom to form the molecular nitrogen, N₂.

Therefore, the correct option is D.

Fishes feed on microscopic algae and animals the primary base of the food chain in water, if they are not checked they will choke the rivers and oceans causing toxic waters. Fish feed to contain them, in the process they grow and increase in numbers but their population is checked by bigger fishes and so on till it reaches a top predator which is usually a large animal.
