Answer:
Polymerase chain reaction (PCR) test is used to duplicate traces of DNA from any living form, for identification purposes. The correct sequence is 1, 3, 2; based on the options given.
Explanation:
The steps to be followed for the PCR procedure are:
<em>Denaturation</em>
Option 1. Involves incubation at 94°C to denature DNA strands into single strands by breaking of weak hydrogen links
<em>Annealing</em>
Option 3. Temperature is lowered to 60°C to allow primers joining their similar DNA sequences.
<em>Elongation</em>
Option 2. Incubate at 72°C to promote the extension of the DNA strands, actually extending them.

Bacteria multiply by binary fission, which results in exact copies (clones) of the parent cell. There for B, 100 would be the answer.
The period of time that begins with the contraction of the atria and ends with ventricular relaxation is known as the Cardiac cycle.
<h3>What is a cardiac cycle?</h3>
The cardiac cycle describes a whole heartbeat from its onset to the beginning of the following pulse. It consists of the diastole, systole, and the interval in between. Heart rate, which is naturally expressed as beats per minute, serves as an example of how a cardiac cycle occurs.
<h3>Cardiac Cycle Physiology</h3>
The left and right halves of the human heart's four chambers make up the body. The right and left ventricles are located in the lower two chambers, while the left and right atria are located in the two top chambers. Pumping deoxygenated blood to the lungs through the pulmonary arteries and the pulmonary trunk is the right ventricle's main job. While the left ventricle is in charge of pushing freshly oxygenated blood to the body through the aorta.
