They prevent bursting of the cells. Aquaporins regulate the water flux in the kidney, red blood cells, etc.
The absense of humans on the island to disturb the biodiversity
Answer:
A. It decreases the activation energy needed to start the reaction.
Explanation:
Catalase is an enzyme found in the cells of organisms exposed to aerobic conditions. It is an enzyme that catalyses the breakdown or decomposition of hydrogen peroxide in the liver to water (H2O) and oxygen (O2).
Catalase, like every other enzyme, operates by binding to the substrate, which in this case is hydrogen peroxide. Catalase then REDUCES or LOWERS the ACTIVATION ENERGY needed to start the reaction.
Not sure about where did you collect the seeds.
But all of the F1 should be tall because the tall plants are dominant originally
F2 will have 3/4 to be tall, assuming this genetic case is determined by only one factor, like Aa
