To test the hypothesis that a particular plant synthesizes storage lipids by using glyceraldehyde 3-phosphate (G3P) from photosy
Nookie1986 [14]

Answer:

Radiolabeled carbon atom in CO2

Explanation:

Photosynthesis is the process by which green plants fix the atmospheric CO2 into glucose. The process includes carbon fixation during which RuBisCo enzyme catalyzes the reaction of CO2 and a five-carbon compound called RuBP to form 3-phosphoglycerate (3-PGA). The 3-PGA enters the reduction phase of the Calvin cycle wherein it is reduced into glyceraldehyde 3-phosphate. Two molecules of glyceraldehyde 3-phosphate make one molecule of glucose.

To test the hypothesis that glyceraldehyde 3-phosphate from photosynthesis is used by plants to synthesize lipids, radiolabeled CO2 must be used. The radiolabeled carbon atom in the CO2 would be fixed in the form of glyceraldehyde 3-phosphate. If the plant uses glyceraldehyde 3-phosphate as a precursor for lipid synthesis, the synthesized lipid molecules would carry the radiolabeled carbon atom.

If a pin is .001 m wide how many red blood cells could you line up across a pin
tresset_1 [31]
According to the question, the width of a pin is 0.001m and the width of a red blood cell is 6-8 μm.
Width of pin in μm = 1000μm.
So approximately 1000/8 red blood cells can fit which is equal to 125 RBCs.

Answer: 125 RBCs
