Answer:
Explanation:
The light reactions of photosynthesis involve light-driven electron and proton transfers, which occur in the thylakoid membrane, whereas the dark reactions involve the fixation of CO2 into carbohydrate, via the Calvin–Benson cycle, which occurs in the stroma (Figure 3).
Mitosis is the way bacteria clone themselves. Depending on the complexity of the organism, it may exhibit crossing over of the chromosomes resulting in non-identical offspring though.
Answer:
Acquired (or somatic) mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.

Answer:
All cells are made from the same major classes of organic molecules: nucleic acids, proteins, carbohydrates, and lipids, They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function.
