Answer:
The correct answer is - A. phototropic and gravitropic.
Explanation:
A plant seedling grows usually two-direction shoots or stems towards light and roots towards the soil or in the direction of gravity. The movement of the plant toward a specific stimulus or effect parts is called tropism and different parts move in a different direction.
The movement of the roots of the plant is usually towards the direction of soil or gravity and this is called gravitropic. The shoot or stem grows from the seedling towards the direction of light and it is called phototropic.
Answer:
Parasympathetic nervous system
Explanation:
The parasympathetic nervous system of the autonomic nervous system is activated to restore the body's energy level after the emergency conditions. This division of the autonomic nervous system triggers the digestion and absorption of nutrients so that body cells obtain and conserve energy.
Some of the responses generated by activated parasympathetic division are increased activity of glands associated with the digestive system and increased the contraction of smooth muscles of the digestive tract. The parasympathetic nervous system also slows down the responses required for physical activities such as heart rate and breathing rate.
The answer is A. Man-made
