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
Answer:
cell
Explanation:
It is the smallest unit of life that can replicate independently. It's the basic structural, functional, and biological unit of all known living organisms. The study of this is called cell biology.
Answer: Equation for photosynthesis is carbon dioxide + water + sunlight→ Glucose + oxygen
In light dependent reactions, energy in form of solar energy is absorbed and converted to chemical energy.
Explanation: During photosynthesis, sunlight is absorbed by the light absorbing pigment called chlorophyll. The absorbed solar energy is converted into chemical energy using carbon dioxide and water as the starting materials with the release of oxygen. The equation is 6 CO2 + 6 H2O + solar energy --> C6H12O6 + 6O2.
Photosynthetic reactions are made up of two parts: the light dependent reactions and the carbon fixation reactions. In the light dependent reactions, chlorophyll and other photosynthetic pigments absorb light energy from the sun and conserve it as ATP and NADPH with a simultaneous release of oxygen. The carbon fixation reactions are driven by the products of the light dependent reactions.
