the second one i’m pretty sure
The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.

Answer:
C
Explanation:
Small objects usually do not permeate the surface of the water due to its high tension. The covalent bonding of water allows for its unique ability of high surface tension.
When there is an increase in water volume in plasma, it causes the hydrostatic pressure in plasma to increase and the osmotic pressure to decrease and as a result, water will move out of plasma.
<h3>How does increased water volume affect hydrostatic pressure in plasma</h3>
When water volume in plasma increases, the hydrostatic pressure will increase.
Increase in water volume will result in a decrease in the osmotic pressure of plasma due to dilution of the solutes in plasma.
Therefore, to maintain homeostasis, water will move out of the plasma by simple diffusion and osmosis.
Therefore, increased water volume causes the hydrostatic pressure in plasma to increase and the osmotic pressure to decrease and as a result, water will move out of plasma.

Answer:
The correct answer is d) circular folds.
Explanation:
Circular folds slow food going through the small intestine so the villi and microvilli can help the food to be processed and digested properly. Also, the presence of these circular folds increases the surface where the nutrients are being absorbed.
