Answer:
The correct option is : b. centrosome
Explanation:
Centrosome is a cell organelle, which acts as the microbule organizing center and also regulates the cell cycle progression in an eukaryotic cell.
During the prophase stage of the cell cycle, the centrosomes are associated with the membrane of the nucleus. The nuclear membrane ruptures during the mitosis and the interaction of the centrosome nucleated microtubules with the chromosomes leads to the formation of the mitotic spindle.
<u>Therefore, mitotic spindles arise from the centrosome.</u>
Answer:If plants were only exposed to green light the rate photosynthesis would decrease. amount of carbon dioxide would increase.
Explanation:
Chlorophyll a: This is the most abundant pigment in plants. Chlorophyll absorbs light with wavelengths of 430nm(blue) and 662nm(red). It reflects green light strongly so it appears green to us.
2. Ionophores because they are class of proteins that move cell membranes. They are small, hydrophobic molecules that increase a cell's permeability to certain ions.
