Questions and Answers

What does the majority of individuals experience in response to the dose according to the graph?

  • No effect
  • A higher than average effect
  • A minimal effect
  • An average effect (correct)

Which group is represented by the smallest number of individuals in the response to the dose?

  • Individuals with a moderate response
  • Individuals with a slightly positive response
  • Sensitive individuals (correct)
  • Individuals with no effect

Based on the graph's distribution, what happens to the number of individuals as the effect of the dose increases?

  • It becomes uniformly distributed
  • It decreases as the effect becomes greater
  • It remains constant regardless of the effect
  • It increases until it reaches a peak and then declines (correct)

Specific Gravity of Liquids

A measure of how dense a liquid is compared to water.

Mineral Oil Density

Mineral oil has a lower specific gravity (0.89) than water (1.00).

Water Density

Water has a specific gravity of 1.00.

Chloroform Density

Chloroform has a higher specific gravity (1.47) than water.

Study Notes

Figure 5.1

  • Depicts layering of immiscible liquids in a test tube
  • Mineral oil is lighter than water
  • Chloroform is heavier
  • Layers are arranged in order of increasing density
  • Mineral oil (sp gr 0.89)
  • Water (sp gr 1.00)
  • Chloroform (sp gr 1.47)
