belka [17]
Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.

Answer:

The answer is b. Both of them are characterized by selective permeability.

Explanation:

  • Option a. states that both, the nuclear and the cell membrane have two layers. This is only true for the nuclear membrane that consists of two lipid bilayers whereas the plasma membrane only contains one layer.
  • c. Only the nuclear membrane has nuclear pores that connect the two bilayers. The pores act as protein channels or passages that allow transport of materials. The cell membrane does contain channel proteins or transmembrane proteins but not protein channels.
  • d. The nuclear membrane separates nuclear contents from the cytoplasm whereas the cell membrane separates cellular contents from the extracellular environment.

Answer:

A. Because energy is lost at every level.

Explanation:

energy decreases as it travels from lower levels to upper levels--which is a logical observation you could make.

Think of it like this--if a fish eats a small organism, it will then spend some of the energy obtained from the organism swimming around--so when a larger fish eats our fish, the energy from the original organism will already be partially lost (from our fish swimming around).

This means that when this pattern continues over multiple levels, we keep losing energy--which limits the environment's capacity for organisms to survive.

Hope this helps, have a lovely day :)
