<em>Answer:</em>
<u>Polymerase Chain Reaction (PCR)</u>
Explanation:
Note that Polymerases Chain Reaction (PCR) is used to amplify food DNA to test for the presence of genetically modified DNA in food products because usually DNA fragments can be isolated from highly processed goods and are sufficiently intact to be amplified by PCR.
The process used by Genetic engineers is <u>called gel electrophoresis </u>where only a small number of regulatory sequences (promoter and terminator sequences) are used to control the expression of the inserted genes.
In the DNA, that is why they are called the building blocks of life.
Answer: One red blood cell will be able to carry one billion molecules of oxygen.
Explanation:
If each red blood cell carries 250,000,000 hemoglobin and every molecule of hemoglobin binds four oxygen molecules, the number of oxygen molecules carried by one red blood cell is 250,000,000 x 4 = 1,000,000,000. That is 1billion oxygen molecules is been carried by one red blood cell. Hemoglobin is a protein present in the red blood cell which binds and transports oxygen to the cells throughout the body. Hemoglobin has four binding sites for oxygen. The binding of one oxygen to its binding site on hemoglobin increases the binding affinity of subsequent oxygen molecules to the other binding sites on the hemoglobin. This phenomenon is known as cooperativity.
Answer:
C) Lower back
Explanation:
The lumbar area is located between the chest, the spine and the sacrum. This area corresponds to the lower back and has five vertebrae: L1-L5. According to this, the answer is that based on this statement, the EMT should expect to find bruising in the lower back.
