<span>sotonic Solution. Isotonic-no water movement across the cell membrane since the concentration of ions are farily equal in and out of the cell. Hypertonic-a condition where cell loose it water content and ultimately plasmolyze due to the higher ionic concentration outside the cell than inside.

B. 245 million
from the end of Carboniferous Period to the beginning of the Triassic period
To the best of my knowledge, there are only two and they would be ribose and deoxyribose
hope this helps if not just let me know
Answer:
Genotype Phenotype
SS 1/4 Short hair 3/4
Ss 2/4 Short hair 3/4
ss 1/4 Long hair 1/4
Explanation:
Both are heterozygous for the trait so we can expect that the cross would be:
Ss x Ss
S s
S SS Ss
s Ss ss
So the resulting off-spring would have the following genotype and phenotype:
1 out of 4 will have a genotype of SS.
2 out of 4 or half will have a genotype of Ss.
1 out of 4 will have a genotype of ss.
But because short hair is dominant the phenotype ratios would differ because Ss and SS would express short hair, so we add up their ration:
Short hair: 1/4 + 2/4 = 3/4
Long hair: 1/4
So in summary:
Genotype Phenotype
SS 1/4 Short hair 3/4
Ss 2/4 Short hair
ss 1/4 Long hair 1/4
I believe your answer would be the stem.
