Answer:
Estradiol has a higher partition coefficient than H+ ions
Explanation
Estradiol is a non-polar and hydrophobic molecule that has a higher partition coefficient than H+ ions, it means that the cell membrane is more permeable to this molecule because it can dissolve in and diffuse within the hydrophobic phase of the membrane. The movement of polar charged molecules (even small H+ ions) requires the input of energy to be able to dissolve within the lipid bilayer. In consequence, the movement of H+ ions requires proteins capable of transporting these protons through the membrane.
Answer:
a) menisci
Explanation:
The Synovial joints contain special cresent-shaped pads which are known as Menisci. A menisci is a crescent-shaped pads (which partly divides synovial joints) that provide additional shock absorption, and provide for a better fit between the articulating surfaces of the bones. In humans, the can be found in the knees,elbows,wrists etc.
The menisci provide structural firmness to where they are being found in the body (i.e knees,elbows,wrists) when it undergoes tension and torsion. They also act to disperse the weight of the body and reduce friction during movement.
Almost all chemical reactions in life process occur in solutions with water.
