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.
Scientific modeling is a scientific activity, the aim of which is also to make something a particular part or feature of the word easier to recognize, define, quantify, visualize, or even simulate by referencing it to an existing and usually commonly accepted knowledge.

Pulmonary valve and Aortic valve
During systole, the aortic and pulmonic valves open to permit ejection into the aorta and pulmonary artery.
<h3>What happen when ventricles contract ?</h3>
When the right ventricle contracts, blood is forced through the pulmonary semilunar valve into the pulmonary artery
- Then it travels to the lungs. In the lungs, the blood receives oxygen then leaves through the pulmonary veins. It returns to the heart and enters the left atrium.
- When the left ventricle contracts, it forces blood through the aortic semilunar valve and into the aorta. The aorta and its branches carries the blood to all the body's tissues.
