Answer:
Question 7:
C
Question 8:
C
Explanation:
Question 7:
If the pH number is smaller, the solution is more acidic. In turn, this means that it contains more H+ ions that OH- ions
Question 8:
A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution
Both light-dependent and light-independed reactions of photosynthesis are similar in a way because they both require chemical energy to proceed.
Photosynthesis occurs in two successive stages. These stages are:
1) The light-dependent reactions
2) The light-independent reactions
The light dependent reactions absorb energy from sunlight and converts it into chemical energy. The chemical energy produced (ATP) by the light-dependent reactions is used by the light-independent reactions for it to function properly. The remaining chemical energy (ADP) in the light-independent reactions is returned to the light-dependent reactions to obtain more energized electrons.
