Answer:
d
Explanation:
four daughter cells are produced in meiosis
Temperature is a quantitative measurement because it can be "measured". Quantitative data is where you record data that is measurable. Qualitative data is research collected from observations.
Answer:food undergo a chemical reaction by bond breaking example for starch to amylose is hydrolysis reaction where there is breaking of 1,4 glycosidic bondd
We are well aware that there are two stages of photosynthesis:
- Light dependent reactions
- Light independent reactions/ Calvin cycle/ dark reactions.
Calvin cycle or light-independent reactions:
This comprise the process during which carbon dioxide enters into the leaves of plants and passes through series of steps to form sugar or food. This process depends on the supply of ATP, (the ATP that is formed previously during light dependent reactions).
Now there are three stages of Calvin cycle:
- 1) carbon fixation
- 2) reduction
- 3) regeneration
During the process of carbon fixation CO2 combines with a 5-carbon compound called RuBP or ribulose-1,5-bisphosphate which results in the synthesis of a 6-carbon compound that splits up in to 2 three carbon compounds called phosphoglyceric acid (3-PGA).
Here out focus will be the process of Reduction.
Reduction is the second stage of Calvin cycle during which phosphoglyceric acid (3-PGA) is converted to glyceraldehyde-3-phosphate (G3P) that is a sugar. During the process of reduction, energy in the form of ATP and NADPH are used for the conversion of 3-PGA to G3P. As 3-PGA is reduced to G3P, therefore this process is known as reduction.
After reduction, a series of reactions occur that lead to the synthesis of glucose but since focus of our question was reduction, so you can see more details of the process in attached figure.
Hope it helps!
