Answer:
the heart is separated into two sides so that it can carry out its function well. The right heart contains deoxygenated blood and the left heart with oxygenated blood. the two sides are separated from each other so that the blood from the two sides don't get mixed. this leads to effective oxygenation of the deoxygenated blood in the right heart through pulmonary circulation and effective oxygenation of the tissues in the different parts of the body by the oxygenated blood of the left heart through systemic circulation.

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.
