Molecules are cooler so they bocme more dense.. move very slow, have less kinetic energy and are not in random motion.
Answer:
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. It is a silvery-white, soft, non-magnetic and ductile metal in the boron group. ... Aluminium is remarkable for its low density and its ability to resist corrosion through the phenomenon of passivation.
Explanation:

The appropriate scatter plot that depicts the correct division for using Divide center to draw trend line is the plot D.
<h3>What are Scatter plots?</h3>
Scatter plots are used to show how much one variable affects another by plotting data points on a horizontal and vertical axis. Each row in the data table is represented by a marker, the position of which is determined by the values of the columns set on the X and Y axes. Scatter plots are graphs that show the relationship of two variables in a data set. It is a two-dimensional plane or a Cartesian system that represents data points.
In order to draw a trend line correctly, divide the points using the divide center method. The dividing vertical line must be drawn at the midpoint (a position where the number of data points to the left and right of the vertical line is equal).
Only option D has a vertical line dividing the 6 data points into two equal portions when the options are evaluated based on this condition.
The diagram is attached.

Well you did not show the figure, but I can show you how to do it.
Suppose the person is 6 feet tall and the bacteria cell is 1 micrometer in length.
So, put both magnitudes in the same units. I will use meter.
Person: 6 feet * 0.3048 m / foot = 1.8288 m, which in orders of magnitud is about 2 m
Bacteria cell: 1 micrometer * 1 m / 1,000,000 micrometer = 1 * 10 ^ -6 m.
Now divide: 2m / 10^ -6 m = 2,000,000
So a person is about 2 million times larger than a bacteria cell.
If the numbers in your figure are different you can use the same method to get a new result according to your figure.
Diffusion if the movement of small molecules across the cell membrane.
Kinetic energy of the molecules results in random motion, causing diffusion.
