Answer:
B) sympathetic and parasympathetic
Explanation:
e autonomic nervous system also called the vegetative nervous system is part of the peripheral nervous system which inervates smooth muscle and glands. Thus, it directly affects the function of internal organs and regulates functions such as the heart rate, digestion, respiratory rate, urination etc. This nervous system control is unconscious.
The autonomic nervous system is divided into: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.
Parasympathetic nervous system works when organism is at rest so it is known as system responsible for "rest and digest functions". On the other hand, sympathetic nervous system works at active and stressful situations and it is known as "fight and flight" system.
Answer:
<em>The correct option is D) the rate of photosynthesis increases and then levels off.</em>
Explanation:
Photosynthesis can be described as the process by which plants make their own food from carbon dioxide and water by using light energy from the Sun. Oxygen is produced as a by-product of this reaction.
As we increase the intensity of light, the rate of photosynthesis also increases. But after a certain time, the reaction rate will level off as there might be enough food produced or the light energy might have caused the temperature to rise which would have caused the enzymes to get denatured.
