The answer is tubulin cyclin and a
cyclin-dependent kinase
The two components that
constitute an active maturation-promoting factor (MPF) is tubulin cyclin and a
cyclin-dependent kinase. MPF stimulates the mitotic and meiotic phases of the
cell cycle. It has the ability to phosphorylate target proteins at a specific point
in the cell cycle and thereby control their ability to function.
Its the mitochondria but I dont have an analogy
5 is b because it makes more sense
Plants get the carbon dioxide they need from the air through their leaves. It moves by diffusion through small holes in the underside of the leaf called stomata. These let carbon dioxide reach the other cells in the leaf, and also let the oxygen produced in photosynthesis leave the leaf easily.
You would the find the greatest diversity of species in a temperate kelp forest.
I hope this helps.
