Put the steps in the process of photosynthesis in order
shepuryov [24]

Step 1-Light Dependent

CO2 and H2O enter the leaf

Step 2- Light Dependent

Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2

Step 3- Light Dependent

The electrons move down to enzymes

Step 4-Light Dependent

Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH

Step 5-Light independent

The ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into simple sugar glucose.

Step 6-Light independent

The calvin cycle converts 3CO2 molecules from the atmosphere to glucose

calvin cycle

The second of two major stages in photosynthesis (following the light reactions), involving atmospheric CO2 fixation and reduction of the fixed carbon into carbohydrate.

Which of the following statements about Avogadro’s Law is false? a. One mole of He occupies 22.4 L at STP. b. At constant P and
Ronch [10]

Answer:

The correct answer to the question which  statements about Avogadro’s Law is false is

c. At constant T and P, doubling the moles of gas decreases the volume by half.

Explanation:

Avogadro's law describes the relationship between the volume of a mass of gas and the number of moles present. Avogadro's law states that at standard (or the same) temperature and pressure, equal volumes od all gases contain equal number of molecules

That is mathematically

\frac{V_{1} }{n_{1} }  =  \frac{V_{2} }{n_{2} }  where

V₁ = volume  of first sample

V₂ = volume  of second sample

n₁ = number of moles in first sample

n₂ = number of moles in second sample
