Answer: Temperature control
Explanation:
Arterio-venous anastomoses (AVAs) are direct connections between small arteries and small veins. In humans they are numerous in the glabrous skin of the hands and feet.
They are very significant in body temperature control. These temperature control are under the dual control of the central nervous system and the local thermal influence. While the arteriovenous anastomoses control the skin temperature through volume changes in the superficial venous bed, the arterioles and capillaries operate by generalized dilatation which results both in increased temperature and in redness of the skin.
Photosynthesis is the term for the process by which plants produce food and energy in the presence of some inorganic substances and solar energy.
<h3>What is the reason behind the above answer ?</h3>
The glass of water won't react when it's placed in the sun's rays.
One explanation for the response is: Water and ambient carbon will be the reactants in the experiment, which should produce glucose and oxygen in the presence of the sunbeam.
The true photosynthetic reaction also uses carbon dioxide and water as reactants, but chlorophyll is a plant pigment that is present during the reaction.

The answer is a person removes their hand after touching a hot stove and a person turns their head toward the source of loud noise.
External stimuli are factors outside of the body that is taken in by receptors and will lead to a response. Examples of external stimuli include temperature changes, vision, hearing, tasting, smelling, and even sunlight for plants.

Due to the overproduction of offspring with only finite resources, species begin to engage in competition for survival. In order to increase their chance of survival, certain species will begin to develop genetic variations that allow them survival advantages.
