Kenton wants to use a graph to identify the chemical components of air. He also wants to show the proportions of each chemical component within air. Which type of graph should Kenton use? a line graph

a scatter plot

a box-and-whisker plot

a circle graph

The correct answer is D. A circle graph

Explanation:

Circle graphs are ideal to show the proportions of a whole. For example, the types of flowers found in an ecosystem. This is because circle graphs visually display all the parts that compose a population, phenomenon, etc. and the percentage of each, which are represented as proportions in a circle.

This would be ideal for Kenton because through this type of graph he can include all the chemical components of air and show appropriately the percentage or proportion of each. Also, other graphs do not fit Kenton's purpose; for example, line graphs are used to show change over time, and box-and-whisker plots are used to show factors such as the median of collected data.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.
