The correct answer is: 2)The light-dependent reactions produce ATP and NADPH, which are then used by the light-independent reactions
The light-dependent reactions is one of the two successive phases that occur during photosynthesis (other is light-independent reactions). The light-dependent reactions use sunlight energy to make the energy storage molecule ATP and the reduced electron carrier NADPH. In the light-independent reactions (also called Calvin cycle), CO2 is absorbed and fixed in order to build three-carbon sugars (glyceraldehyde-3-phosphate) and this process is fueled by, ATP and NADPH from the light reactions.
Answer: Option B) They can be altered reversibly during a reaction.
Explanation:
An enzyme is a proteinous substance that catalyzes a specific chemical reaction. It does not affect the equilibrium of the catalyzed reaction, and it always remain unaltered during the reaction process.
Thus, becoming altered is not a characteristic of enzymes
Charles Darwin established that all species have a common ancestor. The pattern of evolution also was a result of natural selection.
Answer:
Sexual selection
Explanation:
Sexual selection is a specific type of natural selection process by which an organism is able to choose and compete to find a mate, by enhancing the adaptive changes between both the organism (male and female). This process of selection allows some specific members of the population to generate more in number in comparison to the others. This process leads to the increased fitness of the female body by making them over-fastidious.
