Question

Which of the following colonies showed a decrease in size every two weeks after the initial treatment with pesticide?
I. Colony A
II. Colony B
III. Colony C

Three colonies of insects were each treated with a different pesticide over an 8-week period to test the effectiveness of the three pesticides. Colonies A,B , and C were treated with Pesticides , and , respectively. Each pesticide was applied every 2 weeks to one of the three colonies over the 8-week period. The bar graph above shows the insect counts for each of the three colonies 0,2,4,6, and 8 weeks after the initial treatment.

$I only$
$III only$
$I and II only$
$I, II, and III$

hint Hint:

Hint:

Here we analyze the bar graph and then find the answer.

The correct answer is: $text I only end text$

Explanation:

We have given a bar graph that represent the insect counts for each of the three colonies 0,2,4,6,8, weeks after the initial treatment

We have to find which colonies showed a decrease in size every two weeks after the initial treatment with pesticide

Analyze bar graph and then find the solution

Step 1 of 1:
The given bar graph is

By bar graph it is clearly shown that colony A decrease in size every two weeks after the initial treatment with pesticide.
Hence, Option A is correct.
