Temporal isolation is the type of reproductive isolation that would include this example.
Temporal isolation is a type of reproductive barrier in which two closely related species (plants or animals) are prevented from mating and producing sterile hybrids because of their different breeding time. The difference in the breeding time may be year, season (such as fall or winter) or by time of day (daytime or at night).
Answer:
b. prevent the heart from filling properly with blood
Explanation:
The pericardial cavity is the cavity present between the visceral pericardium and the parietal pericardium. It is filled with a fluid called pericardial fluid. In cardiac tamponade, there is an accumulation of excess of the fluid in the pericardial cavity.
The fluid builds up the pressure which in turn compresses the heart. Ventricles of the compressed hearts are not completely filled with blood resulting in reduced cardiac output. Similarly, the return of blood to the heart atria via veins is also reduced in the compressed heart.
First Stage: Separation
Speciation usually begins when a part of a population becomes separated from the rest of their species.
Second Stage: Adaptation
Adaptation in speciation is quite similar, though the groups may evolve different sets of traits if the environmental conditions differ for each group.
Third Stage: Reproductive Isolation
Reproductive isolation is when groups of a same species are reunited and cannot interbreed with each other anymore, so they are now identified as different species.
