Answer:
B.
Explanation:
Glucose is an organic molecule that stores ATP or energy while Adenosine triphosphate (ATP) is an energy-carrying molecule.
ATP used as an active energy source over glucose because ATP is a shorter process and releases energy in a single reaction as glucose first converted into ATP and then used as energy in cellular respiration.
Hence, the correct option is "B".
Answer:
Over our lifetime, our DNA can undergo changes or mutations that result in differences in the DNA sequence and may affect the proteins that are made. Mutations can occur as a natural consequence of errors in DNA replication or as a result of exposure to environmental factors such as smoking, sunlight or radiation.

Answer:
Meristematic tissue
Explanation:
Meristematic tissue contains actively dividing cells that result in formation of other tissue types (e.g. vascular, dermal or ground tissue). Apical meristematic tissue is found in buds and growing tips of plants.
Answer:
D
Explanation:
A: to create sex cells of reproduction.
This is the purpose of meiosis: a cell division process. It creates gametes, or sperm and eggs.
B. to provide the cells with food
This would be eating for animals, or photosynthesis for plants. When animals eat, it provides their cells with food. When plants photosynthesize, they create their own food in the form of glucose.
C. To give the cell energy
This would be cellular respiration. It turns food and glucose into usable energy called ATP.
D.
This is the correct choice. Mitosis is cell division, which means it creates new cells. This allows organisms to grow and repair.
