Ray Of Light [21]

Explanation:

(3) active transport

The molecules would be moving against their concentration gradient from a region of low concentration to a region of high concentration.

While cells facilitate the transport of molecules via movement across the cell membrane, there many different mechanisms. These include passive diffusion, facilitated diffusion,  and passive transport. However some very large molecules require specialized type of active transport, which requires energy in the form of ATP, in order to move substances across the membrane against their concentration gradient.

Active transport is a mediated process that requires an energy input and the use of specialized membrane proteins to move against the concentration gradient. These proteins require energy in the form of adenosine triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules to alter the spatial location of the molecule. For instance, with Na+, K+ pumps in cell membranes.

How might the poison dart frog suddenly increase? How might this affect the ecosystem?
Nimfa-mama [501]

The poison dart frog suddenly increase if the predator that feeds off the dart frogs goes extinct or migrates to a different area then the dart fronts will have a much larger population.

This means that the resources the dart frogs rely on will start to diminish and their prey will have smaller numbers
