Question

Because the variable on the x-axis varies continuously, it makes sense to plot the data on a line graph. (a) Plot each data point from the table onto the graph. (b) Connect the data points with line segments.

Short answer

(a)

(b)

Step-by-step solution

Graph

Numerical data are represented through visual patterns or charts, and such data set with a diagram is called a graph. A typical graph has the X and Y axis, which has independent and dependent variables, respectively.

Bar graphs, line graphs, histograms, and scatter plots are often used in biology to represent the data obtained by experiments.

Explanation of part ‘(a)’

Time after the indication is the independent variable, and it is constantly running; thus, it is plotted in an ‘X-axis. The average amount of DNA per cell varies with the time after incubation, and these are dependent variables and are plotted on the ‘Y-axis.

The points on the graphs are scattered. However, they can be connected through lines.

Explanation of part ‘(b)’

The points are connected with line segments which represent the line graph. Each point indicates the data in a line graph, and each point is joined with a line segment. This type of graph is used when data obtained through experiments are continual.

The data obtained from the experiment determine the relationship between the average amount of DNA per cell and the time after incubation.
