Pacemaker Cells. Cardiac pacemaker cells are mostly found in the sinoatrial (SA) node, which is situated in the upper part of the wall of the right atrium. These cells have natural automaticity, meaning they can generate impulses themselves.

The autorhythmic cells are located in these areas: Sinoatrial (SA), or sinus, node. Atrioventricular (AV) node. Atrioventricular (AV) bundle (also sometimes called the bundle of His)

an insect population is growing in such a way that the number in each generation is approximately 1.5 times that of the previous
ruslelena [56]

Answer:

Approximately 338

Explanation:

Since each generation of the insect is approximately 1.5 times that of the previous generation. Therefore,

Population of insect in the first generation = 100

Population of insect in the second generation = 1.5 × 100

                                                                    = 150

Population of insect in the third generation = 1.5 × 150

                                                                     = 225

Population of insect in the fourth generation = 1.5 × 225

                                                                     = 337.5

The population of insect in the fourth generation is approximately 338.
