b. pass through pores in the capillary endothelium

Explanation:

The fenestrated capillaries and sinusoids have pores in their endothelium. These pores or the intracellular clefts vary in size between the fenestrated capillaries and sinusoids. Sinusoids have larger intracellular clefts. The pores serve as a passage for the movement of water-soluble substances, proteins and other substances that cannot cross the hydrophobic interior of the cell membranes.

Water-soluble hormones also cannot pass through the capillary walls. Therefore, these hormones pass through the pore or the fenestrations present in the endothelium of capillaries.

OverLord2011 [107]
<h2>Answer:</h2>

The correct answer is the option C.

Which is we add equal amount of salt in all the water samples.

<h3>Explanation:</h3>
  • As in experiment we have to indicate that the boiling point of water increases with the addition of salt.
  • Now we also know that water contains many salts as compared to the distilled water.
  • So the boiling points of simple water and distilled water would be bit different.
  • So we cannot choose one for our experiment. Instead we use all water samples of equal volume adding equal amount of salt in all samples.
  • Then we will compare results for a net answer/result of experiment.
