The cell is taking in substances through membrane proteins, without any energy expenditure of its own. The substances naturally

follow their concentration gradient. However, they must go through the protein channels, because they are too large to squeeze through the cell membrane. This process is called

The right answer is facilitated diffusion.

Facilitated diffusion is a diffusion mechanism facilitated by membrane transporters. it's the spontaneous passage of molecules or ions (like the passive diffusion) through a biological membrane through transport molecules (unlike passive diffusion). This process does not consume energy (like the passive diffusion) and therefore does not involve active transportation.

Facilitated diffusion. because the protein channels must help the substance get into the cell based on fitting. It's important to regulating what comes in and goes out.

The correct answer is oxidative phosphorylation.

Oxidative phosphorylation refers to the metabolic pathway in which cells utilize enzymes to dissociate nutrients, thus, discharging energy that is used to generate ATP. In the majority of eukaryotes, this occurs within the mitochondria.

Approximately all the aerobic species carry out the process of oxidative phosphorylation. This pathway is possibly so prevalent as it is a highly effective manner of discharging energy, in comparison to substitute fermentation procedures, like anaerobic glycolysis.

sertanlavr [38]

Answer:

limiting factor

Explanation:

In an ecosystem, certain factors hinder the growth or abundance of the population of organisms. These factors are called LIMITING FACTORS. Limiting factors, which can be biotic, food, drought, predation, disease etc, are factors that inhibits a population of organism from becoming enlarged. There are two types of limiting factors viz: density dependent (depends on size) and density independent (not dependent on size).

This is the case of a drought that dries up the stream that inhabits a population of salamanders. The drought causes the unavailability of water, which will ultimately have an effect on the growth of the salamander population. Hence, the DROUGHT is considered a LIMITING FACTOR.
