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:
Because the element carbon forms the backbone of the molecules that make up cells, one of the most important biogeochemical cycles to life on Earth is the carbon cycle. ... Carbon moves from living things back to the environment as all types of organisms use some of their food molecules as a source of energy.

Explanation:
Electroplating involves the coating of one metal on another metal. It is an electrochemical process. The positive electrode is the coating metal while the negative electrode is the metal on which the coating is to be performed.
Since copper is to be coated on an iron nail. A copper plate is made the positive electrode while the iron nail should be the negative electrode.
The electrolyte used in the process should be a copper salt e.g CuSO4 solution.
As electrolysis progresses, the copper electrode(positive electrode or anode) gradually wears away due to the fact that the copper ions are going into the solution and are being deposited on the iron nail.
