Biology
1 answer:
Alex Ar [27]3 years ago
8 0

Answer:

B. There is a moderate variation in birth weight.

Explanation:

The graph shows the "Number of Babies" on its<em> y-axis</em> and the "Weight in Pounds" on its x-axis. The line graph shows that the re is a moderate variation in birth weight and that occurs when the line of the graph starts to go up after 2.5 pounds and starts going down after 6.5 pounds. Then, the number of babies becomes constant again upon reaching 10.5 pounds.

Letter A <em>(There is no variation in birth weight) </em>is false. The weight in pounds on the y-axis shows a variation from 1 pound to 13 pounds and it also shows that many babies have a 6.5-weight in pounds. So, there is clearly variation here.

Letter C <em>(Variation changes over time)</em> is false. There is no indicator of time in the graph. It only shows two variables.

So, this explains the answer.
