Answer:
The correct answer is - To dissolve the cell and nuclear membranes and release the DNA.
Explanation:
The major function of the detergent in DNA extraction is to dissolve the cell and cellular membranes. It can increase the membrane permeability by pulling apart lipids and proteins that are components of the nuclear and cellular membrane and lyse the cell, from which we want to extract the DNA.
Detergents cause pores in the cell membranes and once these membranes are completely lysed the DNA is released from the cell. It is similar to detergents removes fat (lipids) from dishes.
Ionic compounds are formed from strong electrostatic interactions between ions, which result in higher melting points and electrical conductivity compared to covalent compounds. Covalent compounds have bonds where electrons are shared between atoms.

The answer is they passed the Jim Crow Laws, D
Answer:
The probability of obtaining a "goober" butterfly is 6.25%
Explanation
If there are three possible combinations of butterflies, with yellow and blue being dominant, green is supposed to contain a recessive pattern, so according to Mendel's law of character independence, the pattern RR and BB manifest the dominant phenotype yellow, blue or yellow and blue in spots, the green pattern must be recessive is represented by the letter a, the punnett graph is made, obtaining that 56% present a dominant pattern, 37.5% will be spotted and the pattern recessive must match to generate 6.25% of butterflies “goober”.
Because the three-horned alien is heterozygous, we know that three must be dominant to four, because the gene for the three horns is "hiding" the gene for four horns. Therefore, the three-horned alien has the genotype Tt (T for three horns, and t for four horns). The four horned alien must be tt, because that is the only way that a recessive trait may be seen. If you solve the punnet square on a cross between Tt and tt, you end up with half three (heterozygous) and half four (homozygous recessive) it is a bit easier to explain with something a little "closer to home" if you want me to explain it again, just say so, I don't mind!
