Answer:give me brainliest
Explanation:
A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. Ventricular depolarization occurs in part via an accessory pathway (AP) directly connecting the atrium and ventricle and thus capable of conducting electrical impulses into the ventricle bypassing the AV-His Purkinje conduction system.This term can be confusing, as not all ECG leads contain all three of these waves; yet a “QRS complex” is said to be present regardless.
Answer:
The correct answer is B 4 cells are formed,each having half the number of chromosomes as the original cell.
Explanation:
Meiosis is a specific type of cell division that occur in the germ cells.Meiosis is called reductional division because the 4 new cells those are produced after second meiotic division contain half the number of chromosomes as that of original cells.
During meiosis a cell undergo division two times the division that occur during first time is called first meiotic division resulting in the formation of 2 cells having 2n number of chromosomes.On the other hand the second meiotic division form 4 cells each having half the number of chromosomes.
I believe the correct answer is B
3) is active transport because active transport requires energy.
