Answer:
During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Answer:
The main function of simple columnar epithelial cells are protection. For example, the epithelium in the stomach and digestive tract provides an impermeable barrier against any bacteria that could be ingested but is permeable to any necessary ions. This function is especially important in the colon.

I really hope this is right if so can you give brailiest
One of the main characteristics of secondary granules in the neutrophilic granulocyte cytoplasm is that secondary granules will become pink/tan and will cause the basophilic color to lighten.
Promyelocytes, metamyelocytes, and myelocytes are the precursors of neutrophils, which make up the majority of the white blood cell population. The immature neutrophils are usually found only in the bone marrow.
Myeloid maturation sequence is the next stage of myelocyte. The cytoplasm of this cell starts to produce specific, secondary granules. If the cell is destined to be a neutrophil these secondary granules will be pink/tan and will further cause the basophilic color to lighten and break up. At the beginning of neutrophilia, these secondary granules are most obvious in the golgi area.
As the cell matures closer to a metamyelocyte, they fill the entire cytoplasm. While the cytoplasm shifts to producing secondary granules it also loses the prominence of its primary granules.

Answer:
Option B, The controls on cell growth and divisions can be turned on and off
Explanation:
There are signal proteins that control and regulate the cell growth and division process. For instance, mitogens help in removing the negative controls which would otherwise have blocked the cell cycle progression. Then there are growth factors that synthesize proteins and hence stimulate cell growth. Also there are some survival factors that suppress the apoptosis. Based on these three factors the cell division and growth can be turned on or off.
Hence, option B is correct
