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.
Given molecule:
CH3-CH2-CH2-CH2-CH2-CH2-CH3
- The molecule contain only C and H atoms, hence it is a hydrocarbon
- The C atoms in the linear chain are linked together by carbon-carbon single bonds, hence it is a saturated compound
- It has 7 C atoms and 16 H atoms, hence the molecular formula is C7H16
-The molecular formula can be generally represented as CnH2n+2 where n = 7. This corresponds to the general molecular formula for alkanes
The given molecule is best described as an <u>alkane</u>
Answer: -
Molarity is the term for the concentration expression that relates the moles of solute dissolved in each liter of solution.
Explanation: -
Molarity is defined as number of moles of solute dissolved per litre of the solution.
Molarity symbol is M.
1 M = 1 mol / L
Thus molarity is the term for the concentration expression that relates the moles of solute dissolved in each liter of solution
