Answer:
The correct answer is a The calvin cycle requires products only produced when the photsystems are illuminated .It is often too cold at night for the reaction to take place.
Explanation:
It is true that the reactions of calvin cycle are not directly depends on light but depends on the products such as ATP and NADPH produced during light reaction.
ATP and NADPH is formed by the illumination of photosystems by sun light.So during night time there is no chance for the light dependent illumination of the photosystems.
As a result the ATP and NADPH are not formed during night .That"s why reactions of calvin cycle does not occur at night.
Answer:
A safety pin
Explanation:
Rubber, plastic and food are all non-metals, meaning they are poor conductors of heat and electricity. However, safety pins are made up of steel - a metal - making them good conductors.
Answer:
Sliding friction
Explanation:
SLiding friction produces force
We need to keep in mind that the compound is neutral.
H2SO3
2(+1)+S+3(-2)=0 (since its neutral)
2+S-6=0
S-4=0
S=4
Therefore the oxidation number for sulfur is +4.
