why do different animals havethe body parts that they do have and how do these body part help animals to move the way they do ? how many body parts are needed by different animals from place to place ? what are the similarities and different animals?
Answers
Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive.
The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.
The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.
The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.
Answer:
Different species of animals have different body parts, these are due to the main reason of EVOLUTION. They are used in their own way,
for example,
In earlier fishes are evolved into reptiles, amphibians, mammals. In fishes they use their fins and tails to move and in amphibians they use their legs to move and in most reptiles (snake) they use their own body to move, in mammals they use their hands and legs for locomotion.
