The vacuole in the plant cell stores water
Answer:
Chemical energy that is stored in the food molecules such as sugars are converted into the chemical energy that is available for the cell to perform various cellular functions, it is stored in ATP known as the currency of the cell.
ATP has three phosphate groups attached to adenosine by a phosphoanhydride bond. When a cell requires energy it loses the third phosphate group and releases a huge amount of energy stored in the phosphoanhydride group and form ADP.
When the second phosphate group is lost by breaking the bond again energy is released again left AMP. The breaking of this bond takes place due to hydrolysis reaction
Hemophilia is a genetic disorder that inherited by X-linked recessive pattern. A daughter needs 2 genes to have the disease(or 1 gene to become carrier) but a son only needs to get 1 defect genes from his mother(X gene in male must come from mother). If Xh defected gene and X normal genes, the <span>punnett square </span>would be:
Father(XY)
X Y
Mother Xh XhX XhY ------>XhX= carrier , XhY= sick
(Xh X) X XX XY ------>healthy
