The answer is; B
Rocks have naturally occurring and spontaneously radioactive atoms in them, such as carbon-14. These element isotopes decay into other types of atoms over millions of years. Therefore, by measuring the amount of these radiometric substances, and knowing the half-life of the isotopes, it is possible to postulate the age of a rock to within certain ranges of error.
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.

<span>The correct option is A. Founder's effect is the reduced genetic variability that occur as a result of population production from a small number of colonizing parents. The founder's effects is one of the ways by which nature can randomly produce new species from existing population.</span>
