What are the requirements for photosynthesis to occur, and what is the role of atp in this reaction?
water, oxygen, and chemical energy are required, and atp is changed to adp.
water, carbon dioxide, and electrical energy are required, and atp is produced.
water, phosphate group, and thermal energy are required, and atp is lost.
water, carbon dioxide, and sunlight are required, and atp is produced.

The correct answer is Water, carbon dioxide, and sunlight are required, and ATP is produced.

Photosynthesis is a process of formation of food in green plants and algae, which is divided into light dependent and light independent phase.

In this process, energy from sunlight is absorbed by chlorophyll pigment (through a series of chemical reactions) in the presence of Carbon dioxide and water and converted into ATP and NADPH. The energy is then utilized in the formation of food, which is a carbohydrate ( glucose)

Thus, last option is the right answer.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
