Answer: The P wave indicates atrial depolarization. The P wave occurs when the sinus node, also known as the sinoatrial node, creates an action potential that depolarizes the atria. The P wave should be upright in lead II if the action potential is originating from the SA node.
Explanation:
The number of phenotypes produced for a given trait depends on the number of genes that control that trait. so the answer is 1
Answer: Energy
Explanation:
If there is no chemical bonds in the substance or the bonds in the substances are so strong so there would be no energy released.
This is because there is a need of energy when any bond is formed and energy is released when bonds are broken down.
Energy is stored in the bonds which is released when bonds are broken down.
There would be no energy available for various processes and no movement of energy will take place.
An endothermic reactions involves absorption in which energy is on the reactant side of the question or the left side. Exothermic involves the release of energy in which energy is on the product side of the equation.
