Oxygen levels make no impact, they need CO2.
Sugar concentration makes no impact as that is a product.
Starch makes no impact.
Only light from the choices above is the factor in photosynthesis that could have the greatest effect as it is not a product yet a reactant

The correct answer is option B, Light intensity

Reason -

Light intensity plays a major role in the regulation of photosynthesis. In the absence of light a plant is unable to photosynthesize. As the plant receives light through the chlorophyll , essential chemical reactions takes place thereby releasing free electrons which keep on driving the further processes or reactions in a plant to produce food and oxygen and energy..  

The higher the light intensity, the higher is the rate of photo synthesis

Which statements about wind are true? Check all that apply.
PilotLPTM [1.2K]

Answer:

  • The wind is caused by differences in air pressure.
  • An anemometer is a tool for measuring wind speed.
  • The wind-chill factor has a cooling effect

Explanation:

Winds move from areas of high pressure to areas  of low pressure. This is because the areas of low pressure are composed of hotter and less dense air. The cooler air from the higher pressure region rushes in to displaces the rising warm less dense air. The direction from which the winds prevail FROM is used to name the winds(such as westerlies blow from West to East). A wind vane, windsock and anemometer measure the direction and speed of wind. As wind passes over the skin, it causes a cooling effect (the wind chill factor) because it blows the sweat away from the skin carrying with it the heat.

Antidiuretic hormone A) increases the permeability of the collecting ducts to water by increasing the number of aquaporins. B) i
bazaltina [42]

Answer:

A) increases the permeability of the collecting ducts to water by increasing the number of aquaporins.

Explanation:

ADH is an hormone of the anterior pituitary gland  concern with osmoregualtion. When the solute potential of the blood rises , with decrease in water potential , the   water levels of the blood drops, the osmoreceptors in the hypothalamus sensed this from the circulatory blood and  prompted  the hypothalamus to stimulate the anterior pituitary gland to secrete ADH.

The  hormone is carried in the circulating blood to the walls of the collecting ducts where it binds with the receptors on the walls of the tubule,which increases the fusing and  binding of Aquaporins to the membrane of the collecting ducts to increase re absorption of water back into the blood, raising the water potential of the blood.
