Which of the following statements about cellular respiration is correct? This process occurs mainly in chloroplasts.
Plants and animals use this process to produce ATP.
Oxygen is a by-product of this process.
Plants use this process to produce carbohydrates

Plants and animals use this process to produce ATP.

Explanation:

the first one is wrong because cellular respiration occurs in almost every cell

the third one is wrong because byproduct of cellular respiration is water, not oxygen(oxygen is used in the reaction)

fourth is wrong because carbohydrates are produced by photosynthesis

second option is right because cellular respiration provides energy(ATP) for cells to use(in order to perform lots of processes)

the fossil record provides evidence of a common ancestor to many species.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
