Answer:
In the light-dependent reactions, water molecules do not give up electrons easily so the hydrogen ions remain in the thylakoid compartment. The movement of the hydrogen ions back to the stroma is due to the gradient.
The hydrogen ions have energy as they flow down the gradient that takes place due to the chemiosmosis process, oxygen combines and flows or diffuse.
Answer:
Since there is presence of excess tryptophan, the trp operon will be switched off, since the bacterial need not to synthesize.
Explanation:
Understand the following.
The trp operon is a group of gene that encode biosynthetic enzymes for the amino acid tryptophan.
The transcription gene in the operon is switched off when the tryptophan is in excess but is switched on by the bacterium when the tryptophan is low, so that more tryptophan can be produced.
Answer: (D)
Explanation: biotic factors depend among abiotic factors, meaning that living things need non-living things in order to survive. That also means that biotic factors everywhere including the surrounding area need to be thought of in this sense so that they are able to survive in the environment they are in.
Some organisms, such as plants, can trap the energy in sunlight through photosynthesis and store it in the chemical bonds of carbohydrate molecules. The principal carbohydrate formed through photosynthesis is glucose.

Answer:
Without crossing over, each chromosome would be either maternal or paternal, greatly reducing the number of possible genetic combinations, which would greatly reduce the amount of genetic variation between related individuals and within a species
