In humans, each cell nucleus contains 23 pairs of chromosomes a total of 46 chromosomes. The first 22 pairs are called autosomes which look exactly the same in both males and females. The 23rd pair of chromosomes is called an allosome. These sex chromosomes differ between males and females. Females have two copies of the X chromosome, while males have one X chromosome and one Y chromosome.
Range refers to the y-axis. Domain refers to the x-axis. Range refers to the y-axis. Domain refers to the x-axis.
When your x-axis variables represent discontinuous data (such as different products or sales territories), you can only use a bar graph. In general, line graphs are used to demonstrate data that is related on a continuous scale, whereas bar graphs are used to demonstrate discontinuous data.
