<span>well this is an interesting question and i would say it may depend on what type of cancer cells you are growing and what type of "normal" cells your growing. One possibility is that cell fusion events may occur between your cancer cells and normal cells, thus creating a few options 1 - making the normal cell cancerous, 2 - making the cancer cell that fused with the normal cell not cancerous anymore. 3 - either way the fused cell will have a different genotype and hence be a different cell.</span>
1. A
2. A
3. B
Those are all the answers
Because the AV node takes on the role of a very important delay in the cardiac conduction system. Without this delay, the atria and ventricles would contract at the same time.
<h3>Cardiac conduction system</h3>
The conduction system of the heart sends electrical signals, usually generated by the sinus nodes, causing the heart muscle to contract. Pacemaker signals originating from the sinus node travel through the right atrium to the atrioventricular (AV) along the bundle of His and through branches of the bundle, causing myocardial contraction. This signal first stimulates contraction of the right and left atria then flows to the right and left ventricles. That electric current then allows blood to be pumped throughout the body.
