Answer: D. Genetic mutation
Explanation:
For evolution to occur, there must be a genetic mutation in the genome of an organism such that a new allele is formed.
If this mutation occurred in the sperm and/or the ovum, the mutation will then be passed on through reproduction to the next generation. This leads to more of the subsequent generations having that mutation thereby leading to evolution.
Answer is option a because if a person exhibit trait box close and if a person without trait circle open.
The answer is water, oxygen, and chemical energy are required, and ATP is changed to ADP.
Photosynthesis occurs in the leaves of green plants. During photosynthesis, carbon dioxide and water are converted into glucose and oxygen using the energy of sunlight. Sunlight energy is converted into chemical energy stored in carbohydrates. For this process, ATP is used and, thus, changed to ADP.
