Answer:
D) The porcupine is showing a physical characteristic adaptation and the opossum is showing a behavioral adaptation.
Explanation:
Adaptation, which refers to the ability of an organism to adjust to changes in their external environment in order to survive, is of different types namely: physical/structural, behavioral etc.
- A physical or structural adaptation is a possessed physical characteristics/traits of an organism that enables it adapt.
- A behavioral adaptation is an organisms change in behavioral pattern or responses made to changes in the environment.
According to this question;
- A porcupine is said to have quills on its back which helps protect it from predators. This shows an example of STRUCTURAL or PHYSICAL ADAPTATION, which is the QUILLS it possesses.
- An opossum is said to pretend to be dead and become stiff when threatened. This is an example of BEHAVIORAL ADAPTATION because the opossum responds behaviorally to being threatened.
This illustrates Newton's third law
of motion which states that for every action, there is an equal and opposite
reaction. The sea scallop moves by shooting jets of water out of its shell. The
water shooting out pushes in one direction and there is an equal and opposite
force that pushes the sea scallop forward.
