In the diagrams of mitotic cell division shown, which structure is present in diagram B but in diagram A? -centriole
-cell plate
-cell membrane
-cytoplasm

-cell plate

Explanation:

Diagram A is an animal and diagram B is a plant cell. When dividing through mitosis plant cells form a cell plate during the mitotic phase. However, cell plates are not found in animal cells, as they do not have cell walls. Therefore, the answer must be cell plate.

Cell Plate

Explanation:

Diagram A is an animal cell and diagram B is a plant cell.  In mitosis, animal cells form a cleavage furrow to divide the cell.  In plant cells, a cell plate is formed instead of a cleavage furrow.  The cell plate is made of vesicles that contain the materials to build a new cell wall.  The vesicles fuse, creating a new cell wall that separates the two new daughter cells.  In diagram B, the cell plate is the line in the middle.  

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
