Cholera causes rapid severe dehydration and often leads to death. Oral rehydration therapy, feeding dilute salts and glucose is very effective because:
1. | bacterial damage to intestinal transport of ions is reversed by glucose |
2. | the active transport of glucose and sodium from the cell to the intestine is still intact |
3. | the secondary active transport or co-transport systems of the intestine are still functioning |
4. | the dilute salts and glucose cause removal of excess water from the body |
Consider the given two statements
statement- I | Placing phospholipids into an aqueous solution immediately results in their forming a lipid bilayer. |
statement- II | Phospholipids have a strong affinity for other phospholipids, leading to self assembly by covalent bonding. |
1. | Both I and II are correct and II explains I |
2. | Both I and are correct but II does not explain I |
3. | I is correct and II is incorrect |
4. | Both I and II are incorrect |
