It will transported across plasma membrane by simple diffusion. simple diffusion refers to a process by which molecules will pass across plasma membrane without the aid of channels located on the surface of the membrane. since the molecule identified was polar once it enter in hydrophobic region of the membrane it will not stick since this region is non-polar and therefore it will move easily across that region.
The answer is 4.315 billion kilometers so it would be 4.315 x 10 to the 9th power if that is what is meant and Neptune is the eighth planet outward from the sun (the most distant planet from the sun) so it is a tremendous distance from the earth and would be very hard for humans to reach with such a distance.
Answer:
I know the first and second picture is wrong, not sure what the right one is. Hope this helps some
Answer:
The correct answer is 2 Aldosterone has nuclear receptors inside the kidney cells and activates gene expression.
Explanation:
Aldosterone is a steroid hormone as a result it is lipophilic in nature.Aldosterone is a mineralocorticoid secreted from adrenal cortex.
As it is lipophilic aldosterone can cross the plasma membrane and binds to the nuclear inside the kidney cell which ultimately result in the genes encoding proteins that stimulate water and Na+ ions conservation by the kidneys.
