First of all just to point out that this isn't a biology question :)
Ok so to solve this you have to expand to spare first
8k(4k^2-12k+9)
Then multiply the 8k
32k^3-96k^2+72k is the answer
Von Helomont = He told plant makes it's substance from water not form soil.
Joseph Pristley = He stated CO2 is taken & O2 released by green plants
Igenhousz = He discovered the significance of light & chlorophyll in photosynthesis

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:
When laws are made to protect a species, it is made to stop human interference. Often natural factors also are the reason for a species decline, some of these factors may include, habitat change, climate change and may also be a disease going through the species. In order to truly save a species you would have to isolate them in an area and make sure they are all healthy and the habitat does not change. The only issue with that is, they could lose some of their natural instincts such as hunting or being scared of humans. So a law may not be enough to save a species because there may also be many natural factors interfering with a species survival.
