Answer:
Wilting point
Explanation:
Wilting point is defined as the minimum amount of water in the soil that the plant requires not to wilt. If the soil water content decreases to this or any lower point a plant wilts and can no longer recover its turgidity when placed in a saturated atmosphere for 12 hours.
Answer:
sympathetic nervous system
Explanation:
The sympathetic nervous system is part of the autonomous nervous system which controls the involuntary body functions as heart rate, breath rate, perspiration etc. The sympathetic nervous system is specifically responsible for the increase in the function of body functions when the body perceives a threat. When faced with a threat or distress, the sympathetic nervous system initiates physiological reactions known as the “fight or flight” response, thereby increasing the body’s alertness to such threat. Examples of increased body functions or “fight or flight response” include increased perspiration and increased heart rate, as exhibited by Blair.
Macromolecules are defined as large molecules like lipids, proteins, and carbohydrates.
In the given data, the red colour denotes hydrogen and black denotes carbon. The molecule that needs the majority of red and black color is carbohydrates. Thus, option "A" is correct.
<h3>What are Carbohydrates?</h3>
Carbohydrates can be explained as:
Carbohydrates are the macromolecules, generally referred to as sugar. Carbohydrates are the primary nutrients of the diet along with proteins and fats.
Carbohydrate is a biomolecule that is made up of carbon, hydrogen, and oxygen atoms. The monomeric units of carbohydrates are monosaccharides.
Thus, the correct answer is Option A.

The electrons that chlorophyll loses in the electron transport chain are replenished by water molecules. These water molecules degrade releasing oxygen and hydrogen, the electrons are then supplied to the electron deficient chlorophyll molecules located in the reaction centre of the Photosystem.
