Explanation:
1_ Muscular strength is the amount of force you can put out or the amount of weight you can lift. Muscular endurance is how many times you can move that weight without getting exhausted.
2_ Muscle is the tissue of the body which primarily functions as a source of power. There are three types of muscle in the body. Muscle which is responsible for moving extremities and external areas of the body is called "skeletal muscle." Heart muscle is called "cardiac muscle." Muscle that is in the walls of arteries and bowel is called "smooth muscle."
3_ Muscle fibres: muscle fibers form as a result of the alignment and fusion of myoblasts, which arise from mesodermal somites, to form primary myotubes in the first instance.
4_ The two types of skeletal muscle fibers are slowtwitch (type I) and fast twitch (type II).
Slow twitch muscle fibers support long-distance endurance activities like marathon running, while fast-twitch muscle fibers support fast, powerful movements like jogging or weightlifting.
Answer:
Correlation does not prove causation.
Explanation:
Correlational studies are the type of research that seeks to explore relationships that may exist between variables except cause-effect relationships, so correlational studies are not the most appropriate to prove casualties. The study of relationships between variables in this type of study is descriptive because there is no manipulation of variables, and prediction is the most frequently established type of relationship.
Studies to prove that television programs with aggressive content influence aggressive behavior in children are from correlational studies, as shown in the question above. The problem is that in order to correctly assess the relationship between tv shows and unfaithful behaviors, a cause and effect assessment should be made, since correlation does not prove causation.
