Answer:

Option D, Five radish plants are grown in sunlight, while another five radish plants are kept in the dark.

Explanation:

In a controlled experiment, impact of one independent variable is studied on the dependent variable.  

Here in this study sunlight is the independent variable while the radish plant is dependent variable.  

The researcher wants to study the effect of sunlight on radish plants when they are exposed to it   and compare it to the effect created on radish plants  that are kept in dark.  

Hence option D is correct.

Explain Cellular Respiration clearly.
aleksley [76]
Cellular respiration is the chemical process that makes energy required for day-to-day metabolic functions of an organism. The resulting energy is in the form of a molecule called ATP (adenosine triphosphate). There are two types of cellular respiration: aerobic and anaerobic, but both types start with glycolysis. Glycolysis is the breakdown of glucose molecules which makes some ATP.

Aerobic respiration uses oxygen. It occurs in the mitochondria of cells. The overall chemical formula for this is
C6H12O6 + 6CO2 ---> 6CO2 + 6H20 + 38ATP
In this process, there are multiple stages: glycolysis, Krebs Cycle, and Electron Transport Chain (ETC). All of these stages are used to make ATP, but ETC makes the greatest amount of ATP. The other stages create reactants needed for ETC.

Anaerboic respiration does not use oxygen and is also called fermentation. It occurs after glycolysis. There are two types of this: lactic acid fermenation,which occurs in muscle cells and produces lactic acid, and alcoholic fermentation, which occurs in yeasts and can make bread and alcohol. The process produces some molecules that can produce more ATP in glycolysis.
