A punnett square shows all possible results o a cross between two individuals because it shows the parent genotypes and you multiply them to get the results of an individual
example
parent A: Rr = R, r
parent B: rr = r
r
R Rr
r rr
I’m pretty sure is the 3rd one
Increasing the concentration of carbon dioxide increases the rate of photosynthesis, as there is a greater supply of it that can be used. Of course, you can only add so much carbon dioxide before the plant can’t perform photosynthesis at an any faster rate. Increased carbon dioxide concentration will increase the rate of photosynthesis until it is no longer the limiting factor in the reaction.
It is the mutarotation tests. Mutarotation is the adjustment in the optical turn in light of the adjustment in the balance between two anomers when the relating stereocenters interconvert. Cyclic sugars demonstrate mutarotation as α and β anomeric frames interconvert.
Mutarotation was found by French scientist Dubrunfaut in 1846 when he saw that the particular pivot of watery sugar arrangement changes with time
