If a plant cell completes the cell cycle in 24 hour, how many cells will be produced in a week? explai

The correct answer is 128 cells

Explanation:

Given: 1 complete cell cycle takes 24 hours. It means 1 plant cell divides into 2 cells in 24 hours. Thus, number of hours in one week will be:

24 x 7 days =  168 hours, if one cell cycle  takes 24 hours, then in 168 hours there will be 7 cell cycles.

So, first cell cycle will results into 2 cells and both these cells will divide and will results into 4 cells and then after third division it will 8 cells and so on..

Therefore, at the end of 7th division there will be 128 cells.  

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
