Answer:
The stroke volume of the heart will also rise since exercise is the process where heart is working with great internal pressure or we can say it is in a state of being distended, this ultimately will cause a greater strength of contraction.
This is just in accordance with Stroke’s law that states that stroke volume of the heart increases if the volume of blood in the ventricles, before contraction if all other factors remain same or unchanged. When a large amount of blood rushes in the ventricle, it stretches the muscle fibers of heart that ultimately causes a rise in the force of contraction.
Significance:
This actually helps in the synchronization of output from heart with arterial blood supply, venous return and humoral length without regulating or producing any other changes in the body.
The only option that makes sense to me would have to be false.

It is a genetic change that causes differing characteristics between organisms in a certain species.
The vaccinations triggers the active immunity in the organisms. The active immunity can be defined as the immunity when the immune system of the organism works to produce antibodies against the encountered antigen. Through the vaccination, the organism is given weakened antigens, which triggers the immune system to secrete antibody against it. This encounter to the antigen and release of the antibodies provides lifelong immunization to that particular antigen. After the vaccination is given, it takes almost two weeks for the animal to produce immunity against it.
