because the rat is very close to the human body and to assist the learning student with identification of these structures and systems

How Does Homologous Structures Disapprove Evolution?
They don't, Homologous structures, such as the bones in your forearms and the bones in your cat's and dog's forelegs are that similar because you and your pets are mammals and closely related on the evolutionary tree. Before modern genetic showed this to be convincing the study of morphology was showing us pretty much the same thing; homologous structures support evolution.

Is Kinesiology the science concerned with the action of forces internal and external on the living body?
Stop trying to cheat. Biomechanics is the science concerned with the action of forces internal and external on the living body. Kinesiology is the science or study of movement, and the active and passive structures involved.
What is the study of internal structures of living things?
Anatomy
What is the difference between internal and external validity?
The difference between internal and external validity is in their nature. Internal validity indicates if a study depicts relation between two variables. External validity on the other hand generalizes the study of the variables.
Why is it helpful to study the external and internal structure of the rat?
Why study rat's internal and external structures? "For the pure sake of learning new things", could be one answer. We need to study external and internal structures of a rat in order to acquire correct knowledge about rats. Now for a selfish answer. Since human beings are so much like rats, when we know something more about rats, we nearly always have learned something about ourselves. More so in the past, but still today, we have less moral dilemna in doing testing on rats than on our fellow human beings. In other words, we are willing to cage them, perform experiments that cause irritation, great discomfort or death to a rat that we feel compelled not to when testing ideas with humans. We generally feel that it is immoral to give a human a condition and then to experiment with it. However, we generally don't feel that it is so immoral to give a rat a condition and then to subsequently try to experiment with it. The rat in this last context is a model of a human. what surprises most people is how good a model a rat has been to us. In other words, we are a lot like a rat.
Differentiate between external validity from internal validity?
External validity is the extent that results from a study generalize to other people, places, and situations--how well the findings stand outside the study and the extent to which they can be replicated. The internal validity is that extent to which the study's design enables it to measure and study what it intends to study.
What is the areas of consideration in case study?
the internal and external environment of the company discernible in the case.
Can a study have internal validity but not external validity?
Yes. Internal validity is whether or not the experiment is studying what it intends to. External validity is whether or not the study can be generalised outside of the study. For example, if you had a perfect experiment set up, that measures something perfectly, then it will have internal validity. You haven't, however, shown that you would get the same results in different cultures, or in different time periods. Thus the experiment may not have external validity.

What is the scope and limitations of the study?
The scope and limitations of a study will be influenced by the factors that affect the subject of study. These are internal and external factors which cause direct and indirect influence on the subject.
