Fewer hydrogen ions will be pumped into the Thylakoid when photosystem II being exposed to less sunlight more glucose molecules will be produced.
Photosystem II is the first membrane protein complex in oxygenic photosynthetic organisms in nature. It produces atmospheric oxygen to catalyze the photo-oxidation of water by using light energy. It oxidizes two molecules of water into one molecule of molecular oxygen.
Photosystem II the energy derived from absorption of photons is used to split water molecules to molecular oxygen and protons. The most important function of photosystem II (PSII) is its action as a water-plastoquinone oxido-reductase. At the expense of light energy, water is split, and oxygen and plastoquinol are formed.

Answer:
1. What genes control the growth of cell growth?
2. What is the purpose of this regulation?
3. What happened when the cell growth is not regulated?
Explanation:
What genes control the growth of cell growth? What is the purpose of this regulation? What happened when the cell growth is not regulated?
Above are the questions which an observe would ask about regulation of cell growth. A number of genes such as oncogenes and tumor suppressor genes are involved in the regulation of cell growth and cell division. Regulation of cell growth process ensures that a cell's DNA which is dividing is copied properly as well as repair errors in the DNA. It also ensures that each daughter cell receives a complete set of chromosomes in order to gain healthy daughter cells.
A and B can react to form C and D or, in the reverse reaction, C and D can react to form A and B. This is distinct from reversible process in thermodynamics.
Weak acids and bases undertake reversible reactions. For example, carbonic acid: H2CO3 (l) + H2O(l) ⇌ HCO−3 (aq) + H3O+(aq).
The concentrations of reactants and products in an equilibrium mixture are determined by the analytical concentrations of the reagents (A and B or C and D) and the equilibrium constant, K. The magnitude of the equilibrium constant depends on the Gibbs free energy change for the reaction.[2] So, when the free energy change is large (more than about 30 kJ mol−1), then the equilibrium constant is large (log K > 3) and the concentrations of the reactants at equilibrium are very small. Such a reaction is sometimes considered to be an irreversible reaction, although in reality small amounts of the reactants are still expected to be present in the reacting system. A truly irreversible chemical reaction is usually achieved when one of the products exits the reacting system, for example, as does carbon dioxide (volatile) in the reaction
The answer is A, friction.
Friction is the force that resists movement, and that's why oil is used as a lubricant and why ball bearings are used for machines that need to move with very little friction(i.e. bike wheels, roller skates, fidget spinners)
Answer B is too vague
C will probably reduce efficiency greatly, but not specifically in a way that turns work into thermal energy.
D is the same as C, except that it places the blame on the person using the machine, not the machine itself.
Hope I helped clear it up for you :)
