The data in the table are the result of a paramecium being placed in a hypertonic salt solution.

Which statement correctly describes the bars on a bar graph representing the data?

The graph has five bars of equal height.

The bars range from tallest for very high concentration to shortest for very low concentration.

The bar for very low concentration is twice the height of the bar for medium concentration.

The bar for very high concentration is five times the height of the bar for very low concentration.

    The right answer is C.

    A bar chart, also known as bar graph or column diagram, is a way to graphically represent a set of data or values, and is made up of rectangular bars of lengths proportional to the values represented. Bar graphs are used to compare two or more values. The bars can be oriented horizontally or vertically.

    Since the value obtained at very low concentration (30) is twice the value obtained at medium concentration (15), it can be deduced that "C" is a correct answer. The other answers are false.
