Answer:
In the Sympathetic Nervous System PNS subdivision in which nerve injury would be the most dangerous for life.
Explanation:
In the Sympathetic Nervous System PNS subdivision in which nerve injury would be the most dangerous for life.
It is important for survival to fight or respond to flight because it controls the physiological reaction to a risk or danger and this flight and flight response is activated by sympathetic nervous system. This system is a part of automatic nervous system and operated by various interconnected neuron
It shows evolution and growth from the past and present
Answer:
Interactions between biotic and abiotic components regulate carbon dioxide and water levels.
Explanation:
Abiotic factors include temperature, water, humidity, etc; while biotic factors include all the forms of life. These factors interact in the ecosystem to maintain its homeostasis. For example, during the photosynthesis, plants use the energy of the sun water and carbon dioxide to produce food (carbohydrates) and this process converts carbon dioxide (CO2) to oxygen, which is critical for maintaining the homeostasis of the ecosystem.
I believe it is either B or A, personally i'm leaning towards B, but at the same time, i don't think that we would be obtaining materials via pollination, so it then causes A to make more sense.
