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.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
