Answer:
The laws of thermodynamics are important unifying principles of biology. These principles govern the chemical processes (metabolism) in all biological organisms. The First Law of Thermodynamics, also known as the law of conservation of energy, states that energy can neither be created nor destroyed. It may change from one form to another, but the energy in a closed system remains constant.
Fission and fusion are nuclear reactions that produce energy, though they are not the same. Fission is the splitting of a heavy and unstable nucleus into two lighter nuclei. Fusion is the process where two light nuclei combine together releasing vast amounts of energy.
Independent variable: is the UV light exposure
Control group: people not exposed (sample b)
Dependent variable: skin cancer
Experimental group: (sample A)
The answer would be D. Lactic Acid fermentation because this type of fermentation is anaerobic, or doesn't require oxygen.
