Answer:
A. A tropical rainforest
Explanation: Because its a nice climate and that will make homes for many diffrent kinds of spicies that can survive in that type of environment.
Tetrodotoxin blocks voltage-gated sodium channels, and ouabain blocks sodium-potassium pumps. If you added both tetrodotoxin and ouabain to a solution containing neural tissue it will result in immediate loss of action potential with gradual shift in resting potential.
When the voltage gated sodium channels are blocked then any threshold would not be able to cause an action potential thus, there will be an immediate loss of action potential and any depolarization step.
Moreover, when sodium potential pumps are blocked there is no influx or out flux of sodium or potassium ions thus the concentration of ions inside increases resulting in the gradual shift in resting potential.

Answer: A
Why? It doesn’t kill all living animals(might kill some). No acid rain, and may cause extinction of plants but not most plants. So it has to be A
Answer:
Photosynthesis is the process in which plants materialize the energy from the sun to create food out of carbon dioxide and water. During this same process of Photosynthesis plants release clean oxygen for other living to breath in.
