Earth would basically look like the Moon; minus the craters, of course. This is because with no atmosphere to hold all of the Oxygen near the surface, all life would die off fairly quickly.
A sample of DNA is taken from blood of saliva. PCR makes lots of copies, or amplifies the DNA. We then add restriction enzymes to cut the DNA at palindrome sequences. We then run the DNA through gel Elecrophoresis. Each person has unique short tandem repeats that cause a unique number of cuts by the restriction enzyme. These cuts are separated by size on gel electrophoresis, so no two people have the exact same pattern. We can compare individuals banding patterns to what is found at a crime scene, taken in previous samples, in a baby, and the sample that matches all the banding patterns will be the individual.
The organ system interacts with each other to maintain the normal functioning of the body. The composition of blood changes due to this interaction. The change is the blood going out from the lungs is deoxygenated and the one coming to the lungs is oxygenated.
<h3>What is the interaction of the respiratory and circulatory systems?</h3>
The respiratory system involves inhalation of oxygen and using this to release energy and exhalation of carbon dioxide.
The circulatory system is comprised of the heart and blood vessels. The heart pumps blood to different body organs through these blood vessels.
The transfer of oxygen is done with the help of blood. During this transfer, the composition of blood changes from being oxygenated means having oxygen to deoxygenated means having carbon dioxide.
Thus, in this way, the interaction changes the composition of blood.

Chronic backache
<span>The nurse should provide preventive measures for chronic backache as a consequence of lordosis when caring for this client.

Diastasis occurs as the pregnancy progresses when the rectus muscle stretches to the point that it separates. It is not caused by lordosis. Edema in lower extremities occurs due to an impeded venous return caused by pressure of growing fetus on pelvic and femoral areas. It is not caused by lordosis.</span>
