A: A bone consists of bone tissue, cartilage, dense connective tissue, epithelium, adipose tissue, and…

Q: Predict the appearance of the muscle fibers of an athlete who trains to run marathons. What type of…

A: Muscle is one of four animal essential tissues. Muscles are soft tissue present in most mammals.…

Q: Compare the different types of muscle contractions.

A: Muscles are formed of muscle fibers. The bundle of muscle fibrils forms a muscle fiber. The muscles…
