The bottom line difference between passive and active transport through a cell membrane’s is
Ahat [919]
<h3><u>Answer;</u></h3>

Active transport uses energy and passive transport does not

<h3><u>Explanation</u>;</h3>
  • <u>Passive transport occurs when materials move across cell membranes without using cell energy (ATP). </u> Examples of passive transport include; diffusion, facilitated diffusion, and osmosis. It moves small molecules like water, oxygen, carbon dioxide and glucose.
  • <em><u>Active transport on the other hand involves the movement of materials across the cell membrane that requires the use of cell energy (ATP)</u></em>.
  • In other words the difference between active transport and passive transport is that passive Transport moves ions from high concentration to low, using no metabolic energy while active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.

Fireflies emit flashes of light because of chemical reactions, which occur in their abdomens. The rate of the chemical reactions
damaskus [11]

Since the rate of flashing depends on the rate of reaction, it means that fireflies will flash slower during cold weather.

<h3>How does temperature affect rate of reactions?</h3>

Temperature affects the rate of reaction such that reactions are faster at high temperatures and slower at low temperatures.

Thus, since the rate of flashing in fireflies depends on the rate of reaction, cold temperature means that the rate of flashing will be low as compared to warm temperature.

In other words, fireflies will flash lower during cold weather and vice versa.
