Animals lose heat through the surface areas of their skin. A small animal, such as a mouse, uses a much larger proportion of its
Goryan [66]

Answer:

Because of the difference in surface area to volume ratio

Explanation:

Surface are to volume ratio is the area of an object that is exposed to the external environment (surface area), compared to the amount within an object (volume).

Therefore an elephant has a lower surface area to volume ratio than a mouse.

The smaller an object is the greater its surface area to volume ratio.

Small animals have much more surface area per mass than large animals. With so much surface area, they lose heat very quickly. So, a mouse, with a lot of surface area per mass, must spend a lot more energy to stay warm than a large animal.

In the history of Earth and the evolution of cells, aerobic cells appeared first and anaerobic cells appeared later.
Andreas93 [3]

Answer:

False

Explanation:

Scientist believe that the primitive atmosphere lacked free oxygen. Oxygen is a highly reactive molecule that would have made difficult for complex macromolecules to appear and then create life.  Rocks from the precambrian period support this theory.

Anaerobic cells appeared first, then photosynthesis appeared filling the atmosphere with oxygen and the aerobic organism develop cellular respiration to obtain energy, a process more efficient than anaerobic respiration.
