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.

Answer:
Ingestion: Consuming something orally, whether it be food, drink, medicine, or other substance; the first step of digestion. bolus: a round mass of something, especially of chewed food in the mouth or alimentary canal.
Propulsion: Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction.
Mechanical Digestion: Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.
Chemical Digestion: Chemical digestion involves the secretions of enzymes throughout your digestive tract. These enzymes break the chemical bonds that hold food particles together. This allows food to be broken down into small, digestible parts.
Absorption: Absorption is a condition in which something takes in another substance. The process of absorption means that a substance captures and transforms energy. The absorbent distributes the material it captures throughout whole and adsorbent only distributes it through the surface.
Defecation: Defecation is the term given for the act of expelling feces from the digestive tract via the anus.
