Lipid-soluble hormones readily diffuse through capillary walls, whereas water-soluble hormones, such as proteins, remain in the
blood.a. pass through capillary cells.b. pass through pores in the capillary endothelium.c. be moved out of the capillary by active transport.d. remain in the blood.e. be broken down to amino acids before leaving the blood.
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.
The hydrosphere provides almost all the water at or near the earth's surface. It is important to the biological and geological processes as it is a continuous cycle of recycling water between the oceans and atmosphere.
<span>Amino acids are "read" in groups of three. If the first "a" is deleted, the first amino acid from "tcg" will be correct, but every amino acid after that will be wrong. The second amino acid, for example, would be "ggt" instead of "agg".</span>
