Answer: c. The Earth’s surface is responsible for a small fraction of heat radiation to space.

Explanation:

In later ages the large amount of sun's energy is reflected back by the terrestrial surface back to the space. But now due to the abundance of large concentration of greenhouse gases in the atmosphere is responsible for the absorption of thermal energy from sunlight by these gases causing the atmosphere to be hot. This is the reason of global warming. Now only small fraction of heat is radiated back to the space.

How did the increased availability of atmospheric oxygen affect the evolution of the eukaryotic cell?

hichkok12 [17]

T<span>he cell requires oxygen, and eukaryotic cells are expensive to run. they require a lot of energy and nutrients, and oxygen is one such component. the oxygen is necessary for aerobic respiration, which allows the cell to do a lot, including evolve, proliferate, adopt new niches, habitats, biochemical habitats, sustain life in extreme conditions, and perhaps eventually co-operate with other cells and create multicellular life. Multicellular life is virtually impossible without aerobic respiration. </span>

What processes allows cells to concentrate material that is present only in very small amounts in the extracellular fluid?

AleksandrR [38]

Answer:

receptor-mediated endocytosis

Explanation:

A selective mechanism that is responsible for endocytosis and transcytosis of the small amounts of materials that are present in the extracellular fluid is known as receptor-mediated endocytosis.
The various molecules that can be taken up by this process include hormones, metabolites, proteins as well as certain viruses.
This process is also known as clathrin-mediated endocytosis.
In this process, the receptors that are present on the surface of the proteins are captured by a molecule which is the target site for the protein and internalized by membrane internalization (endocytosis).
