Answer:
Explanation:Define as it relates to adaptation
The sequence of impulse through the cardiac conduction system starts from SA node passes to AV node to atrioventricular bundle fibers and finally to Purkinje fibers.
Heart is an organ that receives oxygenated blood form lungs and deoxygenated blood from different parts of body. Oxygenated blood is transported to different organs and deoxygenated blood is transported to lungs for oxygenation.
Now, to perform this transportation, the auricles and ventricles of heart contract and relax. In order to contract and relax, impulse generation is required, which begins at SA node or Sinoatrial node. It is also referred to as pacemaker of the heart. SA node contracts the atria and the impulse transfers to AV node or Atrioventricular node.
This is followed by transfer of impulse to atrioventricular bundle fibers which further passes it on to Purkinje fibres for ventricular contraction. Now the blood is sent to lungs and aorta as per it's oxygen status.

Answer: A
Explanation:
"That's what evolution is all about: tiny changes in organisms of a species over a huge amount of time."
A laparoscopic cholecystectomy is the removal of gallbladder using a laparoscope which is a narrow tube with a camera and compared to the open cholecystectomy, it only has small incisions instead of a large one. The patient's stomach as part of the procedure will be inflated with carbon dioxide and will be deflated right after the procedure. The nurse should inform the patient then that it is a normal side effect of the carbon dioxide placed into the stomach prior to the start of the procedure and it would just be gone yet patient would just feel a little bit discomfort.
They show how all creatures have adapted such as giant dinosaurs are now tiny lizards =D<span />
