B. New substances are formed. In a chemical reaction, the starting molecule must be changed or turn into another. For example: rusts that form in a tin can is a chemical reaction. The iron in the can combines with the oxygen in the atmosphere, creating rust (iron oxide), which is a different substance.

Explanation:
None of these are found in an animal cell.
Doubtlessly the germination rate of the radish seeds is more noteworthy when the pH is more unbiased, similar to when putting in water. There wasn't any distinction in the development of the radish seeds between the soluble and acidic arrangements in my analysis. The seeds did not develop in either arrangement. The radish seeds appeared to endeavor to develop in the acidic arrangement. The reason I say endeavored to develop is on account of you could see greenish spots where the seeds were put. The radish seeds had no adjustment in the antacid arrangement. Neither one of the solutions is a decent situation for radish seeds to develop.
The answer is graded potential<span>. Its made of various action potentials that depolarise the neuron incrementaly, in short interspersed intervals that do not give time for the neurons to return to resting potential. Therefore, the actions potentials, of varying sizes, grade up in sum and when they cumulatively reach the threshold level, they invoke an impulse in the nerve</span>
Answer:
Chlorophyll absorbs the red and blue segment of the white light and photosynthesis occurs most efficiently at these wavelengths.
When the light falls on the plant, the chlorophyll pigment absorbs this light and electrons in it gets excited.
This process occurs in a complex protein system which is collectively called as a photosystem.
