The electrical current (signal) moves slower through the the conductive cells compared to it's movement through regular cardiomyocytes (heart muscle cells).

False

Explanation:

 The heart transmits electric current that causes contraction of the heart muscles. The depolarization to threshold caused  by positive charged ions entering the cell occurs faster in conductive cells compared to the surrounding cardiomyoctes.

Due to this, the conductive cells are able to direct the signal in an organized manner so that the heart can contract promoting proper blood flow.                        

answer: 21

step-by-step explanation:

divide 630 by 30. 30 goes into 630 21 times
