Questions and Answers

What does the Y-axis represent in the graph?

  • The sensitivity of individuals to the dose
  • The effect of the dose
  • The dose administered
  • The number of individuals (correct)

Which statement best describes the majority of individuals in relation to the given dose?

  • They are highly resistant to the dose.
  • They tend to respond with an average effect. (correct)
  • They exhibit a great response to the dose.
  • They show little effect from the dose.

What characteristic of the distribution shown in the graph is accurately described?

  • It reflects a skewed distribution to the left.
  • It is uniform across all individuals.
  • It indicates that sensitivity is equally distributed.

Flashcards

Specific Gravity of Mineral Oil

Mineral oil has a specific gravity of 0.89, meaning it's lighter than water.

Specific Gravity of Water

Water has a specific gravity of 1.00.

Specific Gravity of Chloroform

Chloroform has a specific gravity of 1.47, heavier than water.

Liquid Layering

Immiscible liquids arrange themselves in layers based on their specific gravity, with the least dense on top and the most dense at the bottom.
