Maria should replace the water in the vase with a different color in order to confirm her hypothesis. Example, if she replaces it with blue water, according to her hypothesis, the pedals of the Cut Flower should turn blue.
Answer:
Option A
Explanation:
Osmotic lysis is the bursting of cell due to over intake of fluid. The inhibiting enzymes prevents the formation of cell wall which act as a semi permeable membrane to the external fluid and hence regulate its movement inside the cell. In a plant cell (which has cell wall) dying of cell due to bursting is not possible while in animal cells which only has plasma membrane (i.e selectively permeable to water) water or any other fluid is allowed to move inside the cell and hence the cell size increases.
Hence, option A is correct

THE ANSWER IS

option B ventral nerve cord is the right option
Well, since the phenotype is checkered, we assume that there is codominance where offspring phenotype is a mix of the parents' phenotypes. If the offspring phenotype is a blend between the two parents', then there is incomplete dominance.
Genotypes of codominant parents is usually represented by upper case letters B and W, and the mixed genotype would be BW.
Since the genotype BW is 100%, the rooster's genotype can only be BB and the hen's genotype can only be WW to result in 100% BW.
The correspond Punnett square is therefore
B B
W BW BW
W BW BW
By the way, apparently that this example is academically made up, there are no checkered chickens. I don't know if this is true, since I don't raise enough chickens to verify this. :)
