DNA samples are added into wells with the help of electric current because of the presence of charges.
How dna samples added to the wells?DNA samples are added into wells at one end of a gel whereas an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
So we can conclude that DNA samples are added into wells with the help of electric current.

1. Cross a red-flowered snapdragon with a white flowered one. Then perform
another cross with the offspring of the first cross. List genotypic and
phenotypic ratios for each cross.
The genotypic ratio from the crossing of a red-flowered snapdragon with a white flowered and advancing it to F2 one would be 1 R1R1 : 2 R1R2 : 1 R2R2 and the phenotypic ratio would be 1 red : 2 pink : 1 white
Monohybrid crossingThe red flower snapdragon is homzygous for the R1 allele while the white flower one is homzygous for the R2 allele. The R1 allele has incomplete dominance over the R2 allele.
Crossing R1R1 individual with a R2R2 individual:
R1R1 x R2R2
R1R2 R1R2 R1R2 R1R2
All the F1 progenies are R1R2 (pink)
Crossing two F1 progenies:
R1R2 x R1R2
R1R1 R1R2 R1R2 R2R2
Genotypic ratio: 1 R1R1 : 2 R1R2 : 1 R2R2
Phenotypic ratio: 1 red : 2 pink : 1 white

Write and solve an equation that will help you figure out how much of the remaining pizzas will be eaten. Explain the steps you took to solve the problem. ned the aser
Answer: 4 1/4
Step-by-step explanation:
Convert 5 2/3 to an improper fraction. 3 x 5 = 15 + 2=17
17/3 x 3/4 = 51/12= 4 1/4 of the remaining pizza will be eaten
Answer:
4 1/4
Explanation:
convert 5 2/3 to an improper fraction.
multiply the improper fractions = 17/3 x 3/4 = 51/12
reduce fraction 51/12 to 4 1/4
4 1/4 is the total

Magnification is x100. What is the actual size of one of these epithelial cells?
Answer:
The results show a range of epithelial cell diameters from 8-21 microns with 97% of the measurements lying in the 9-17 microns range. Pleomorphism is marked. The mean cell size was 12.7 microns. Large differences exist in mean cell size between individuals, but no correlation was found with age, diabetes or cataract.
Explanation:
The magnification is x100, and we assume that the cell is 1mm when observed under the microscope, then the actual size would be 1mm divided by 100, which is 0.01mm or 10 micrometers.
The actual size of the epithelial cell can be calculated using the magnification factor and the observed size under the microscope.
The actual size of the epithelial cell can be calculated using the magnification factor and the size of the cell as seen under the microscope.
In this case, if the magnification is x100, and we assume that the cell is 1mm when observed under the microscope, then the actual size would be 1mm divided by 100, which is 0.01mm or 10 micrometers.
