Answer:
Three types of muscles are the cardiac muscles, smooth muscles, and the skeletal.
an example of a cardiac muscle muscles that contract the heart to pump blood. this heart muscle is a striped muscle in the walls of the heart. it is involuntary meaning a person cannot control it consciously.
an example of a smooth muscle is muscle tissue which is used by various systems to apply pressure to vessels and organs. this muscle is also involuntary and are usually in sheets or layers. your brain and body tell these muscles what to do without you even thinking about it.
an example of skeletal muscle are your biceps, deltoids, or even pectoralis. this muscle is called striated, meaning long or streak like, because the light and dark parts of the muscle fibers make them look striped(striated). these muscles are voluntary, which means they can control what you do.

Explanation:
Dependent on the level of comparison four types of homology are defined: ( 1) Iterative ( = serial = homonomy), (2) ontogenetic, (3) di- or polymor- phic, and (4) supraspecific homology. ... Scientists have recently been paying renewed attention to the homology question.
Homology is the study of likeness, the similarity between species that results from inheritance of traits from a common ancestor. The study of similarities is broken up into three main categories: structural, developmental, and molecular homology.
