Answer:
Tanning of DNA using UV light at different time (1 minutes, 15 minutes, and 30 minutes)
Explanation:
Independent variable is the variable that was controlled or change and in this case it is the tanning of DNA with UV light at different times and the dependent variable is what is measured or the effect of the change in the independent variable which is DNA damage and the control was the cells that did not receive the treatment.
Answer:
Photosynthesis is the process by which plants prepare food using water, sunlight, chlorophyll and carbon dioxide
The weak die off and strong survive
Answer:
A. can be used for both catabolism and anabolism
Explanation:
An amphibolic pathway can be used for both catabolic and anabolic reactions.
During Catabolism, complex or large molecules are broken down into smaller ones. Catabolism produces energy.
During anabolism, larger molecules are made from simple ones. Anabolism uses up energy.
Both catabolism and anabolism are needed in the cell.
An example of an amphibolic pathway is the Kreb's cycle. It produces intermediates (molecules) that are used by both catabolic and anabolic pathways.
