Answer:
a. ATP and NADPH
Explanation:
Light-dependent reactions of photosynthesis include splitting of water in the presence of sunlight and release of electrons. The electrons move from the reaction center of the PS-II via electron carriers to the PS-I. From the reaction center of PS-I, the electrons finally reach NADP reductase and reduce NADP into NADPH.
During this electron transfer via electron carriers, a proton concentration gradient is generated across the thylakoid membrane. The energy of this gradient is used to drive ATP synthesis. ATP and NADPH formed during the light-dependent phase of photosynthesis are then used during the reactions of the Calvin cycle.
Answer: Experience 1 is the one that has the greatest reliability.
Explanation: Because of this potential variation, biological experiments need to have a large sample size and preferably be repeated several times. With more samples and repeating the experiment more often, the probability of arriving at a wrong conclusion due to random variation is diminished. As experience 1 has had several repetitions, it is the experience with a more reliable result.
Explanation:
Results in a decline in CD4+T cell numbers below the critical level, and loss of cell-mediated immunity. Therefore the body becomes progressively more susceptible to opportunistic infections and cancer.
