Answer:
D
Explanation:
Vitamin C is one of the vitamins that humans can't produce in their liver. They need this vitamin from the external environment in the form of food. About 75- 90mg/day is it's the normal dosage. So, option D is correct.
Dominant allele for height T
Recessive allele t
Genotypes for tall Tt or TT
Genotype for short tt.
If there is 8,216 plants, 3,122 are short, which means that 5094 are tall.
Frequency of the recessive homozygous is q2 and it is 3122/8216=0.38, which means that only q=0.62
If p+q=1 (HW equilibrium), than p=0.38
Frequency of dominant homozygous is p2=0.14
The number of dominant homozygous is 0.14*8216=1183
The number of heterozygous is 5094-1183=3911
The number of recessive homozygous is 3122
Answer:
In the decolorization step alcohol is used which destain the gram-negative bacteria but not gram-positive because alcohol degrades the LPS cell wall of gram-negative bacteria which allow the crystal violet to moves out of the cell.
So if we use too little alcohol then the alcohol will not able to decolorize all the gram-negative bacteria and most of the cell in the culture will appear violet or purple because crystal violet retained in the cell wall of bacteria.
So the sample of gram-negative bacteria will appear as gram-positive bacteria under the microscope.
