What are physical characteristics that help an organism survive

Special characteristics adapted by specific animals allow them to carry out unique abilities in order to survive. For instance, a cheetah's long tail helps it balance when running at rapid speed in order to hunt. Or an arctic woolly bear caterpillar is able to be frozen and fill it's body with an antifreeze hormone that allows it to survive temperatures below freezing.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
