The answer is D, photosynthesis and respiration.


—Evidence—

Oxygen is a byproduct of photosynthesis and, correspondingly, carbon dioxide the byproduct of respiration.

Oxygen gives our cells the ability to break down food in order to get the energy we need to survive. Although other animals may use different organs to breathe with, they all get oxygen into their bodies through respiration.

Which description accurately compares cellular respiration and photosynthesis?
Genrish500 [490]

Answer:

The correct answer will be option-A.

Explanation:

Photosynthesis is a process which uses sunlight energy to synthesize food in the form of glucose. The process takes place in the chloroplast in two stages: light-dependent reactions and light-independent reactions.

The light-independent reaction produces to convert the carbon dioxide from the atmosphere to glucose through the Calvin cycle. The carbon gets fixed and reduced form+4 state to +1 state.

Respiration is the process which oxidizes the glucose molecule to produce energy in the form of ATP molecules. This ATP is utilized by the cell to perform various functions.

Thus, option-A is the correct answer.

Hey There!!

The answer to this is: C) a factor that may affect an experiment or investigation. This is the best answer. A and B can be eliminated. D describes a controlled variable which is more specific than a scientific variable, thus C is the best answer. It is the best description of just a scientific variable. And, The second one is B: Robert Hooke was a famous scientist who experimented with springs (metal coils). He found that the farther you stretched the spring, the larger the force with which the spring pulled back on you.

Hope It Helped!~ ♡
