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.
U will need to actually post a question, i dont see one
Answer:
The correct answer is d. suggests that the time since divergence may not be sufficient for complete reproductive isolation to have occurred.
Explanation:
Polar bears are evolved from brown bear and grizzly bears are subspecies of brown bear so polar bears and brown bears are different species. These two species habitat is different so they are geographically isolated but due to the melting of ice by global warming, their niche started overlapping.
Commonly they do no reproduce with each other because of the reproductive isolation but they can produce viable hybrids called growlers and pizzlies if interspecies reproduction takes place which shows that the time interval since divergence is not enough that can make these two species completely reproductive isolated. So the right answer is d.
