Answer:
Answer is below.
Explanation:
Photosynthesis is a process that involves three main actors (or ingredients); sunlight, water, carbon dioxide.
Statistics has it that there was no sunlight all through the day.
- Let's check then if there was availability of water and the gas carbon dioxide.
There was rainfall all day
- This means that some photosynthetic activity would take place.
What about the gas that plants breathe in?
- There is always substantial amount of CO₂ in the atmosphere.
A SECOND WAY TO LOOK AT IT IS:
by checking the two stages of photosynthesis.
- In the first stage, sunlight is the main actor. Sunlight is trapped and stored as energy in the chloroplasts of green plants.
- In the second stage, CO₂ is the main actor. With CO₂, the chemical compound - from the first stage - ATP is used to produce sugar and organic compounds which are the food of/for green plants.
Answer:
The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.

Answer:
DNP produces the loss of the proton gradient (i.e., the energy of the proton gradient is dissipated in the form of heat instead to produce ATP)
Explanation:
2,4-Dinitrophenol (DNP) acts to shuttle H+ ions across cellular membranes, bypassing the ATP synthase used by mitochondria to generate ATP during cellular respiration. Since DNP is able to bypass ATP synthase, this compound uncouples the phosphorylation of ADP by the ATP synthase from the process of oxidation (i.e., transport of electrons). For example, in muscle cells, DNP may be used to shuttle calcium ions (Ca +) from mitochondrial stores, and free intracellular Ca+ ions are evidenced to produce muscle contraction.
