Answer:

The correct answer is - because 3×3×3 has the highest Surface area to volume ratio, diffusion in and out of the cell would be faster.

Explanation:

It is known that if the size of a sphere or cell increases, the volume is a cube, and the surface area is squared therefore volume increases faster than the surface area. If the volume is more and the surface area is less than diffusion will be less effective. diffusion takes longer and is less effective.

The decrease in the surface-to-volume ratio leads to diffusion to get less efficient. The Surface-to-volume ratio of a sphere decreases as the sphere gets bigger.

Sav [38]

Robert Hooke is the first person to observe cells as microscopic structures.

He was of British descent and, fun fact, he discovered cells by looking at a sliver of cork under a microscope lens (although the 'fun fact' is heavily simplified).

Which of these energy transformations is taking place in the chimpmunk when its cells use the plants sugars to carry out cell pr
Alexeev081 [22]

Answer:

This question lacks options, the options are:

A. chemical energy -> kinetic energy

B. kinetic energy -> solar energy

C. solar energy -> chemical energy

D. kinetic energy -> nuclear energy

The correct answer is A.

Explanation:

All living organisms need energy to carry out certain processes in their body. This energy is obtained in form of ATP (chemical energy) when their food molecules is broken down via a process called CELLULAR RESPIRATION.

This chemical energy (ATP) is needed to perform cellular processes in the body. According to this question, a chipmunk (animal) will utilize the energy it derives (ATP) from breaking down plant sugars to carry out its cell processes. This means that it will transform CHEMICAL ENERGY → KINETIC ENERGY.

Note that, kinetic energy is the energy due to motion in the Chipmunk.
