Question

most of the individuals in the population would be affected at which point on the graph?

Explanation:

Step1: Analyze the graph

The graph shows a normal - distribution - like curve (bell - shaped curve) where the x - axis is 'DOSE' and the y - axis is '# ORGANISMS'. In a normal distribution, the highest point of the curve (the mode) represents the value that occurs most frequently.

Step2: Identify the highest point

Looking at the points \(A\), \(B\), \(C\), and \(D\) on the graph, point \(B\) is at the peak of the curve. Since the y - axis represents the number of organisms, the peak of the curve (point \(B\)) indicates the dose at which the maximum number of organisms (most of the population) is affected.

Answer:

B
