Question 1

Which organelle is responsible for producing ATP through cellular respiration in eukaryotic cells?

Accepted Answer

Mitochondria

Answer

Mitochondria are the site of aerobic cellular respiration, producing the majority of ATP (adenosine triphosphate) used by the cell.

Question 4

What is the process by which water vapor cools and transforms into liquid water droplets, forming clouds?

Accepted Answer

Condensation

Answer

Condensation is the phase change from gas (water vapor) to liquid. In the atmosphere, water vapor condenses around dust particles at the dew point to form cloud droplets.

Question 5

What is the atomic number of an element?

Accepted Answer
