1. What is the correct plural of chair?
- A. Chair
- B. Chairs
- C. Chaires
- D. Chairies
Correct answer: B
Rationale: The correct plural form of 'chair' is 'chairs,' following the regular pluralization rule by adding 's.' Choices C and D, 'Chaires' and 'Chairies,' are incorrect because they do not follow the standard English pluralization rule. Choice A, 'Chair,' is the singular form and not the plural form of the word.
2. In experimental design, which variable is measured as a possible effect and is plotted on the y-axis?
- A. Independent, x
- B. Independent, y
- C. Dependent, x
- D. Dependent, y
Correct answer: D
Rationale: The correct answer is D: 'Dependent, y.' In experimental design, the dependent variable is the outcome that is being measured or observed as a result of changes in the independent variable. It is typically plotted on the y-axis of a graph to represent the effect or response to the changes in the independent variable. Choice A 'Independent, x' is incorrect because the independent variable is the variable manipulated by the experimenter and is usually plotted on the x-axis. Choice B 'Independent, y' is incorrect as the independent variable is not plotted on the y-axis. Choice C 'Dependent, x' is incorrect because the dependent variable is not typically plotted on the x-axis in experimental design.
3. Given the style of writing for the passage, which of the following magazines would be the best fit for this article?
- A. Scientific Spelunking
- B. Family Fun Days
- C. Adventures for Men
- D. Mud Magazine
Correct answer: B
Rationale: The article's style is light-hearted and aimed at families looking for outdoor adventures. It suggests activities suitable for families with children, making Family Fun Days the best fit among the given magazine options. 'Scientific Spelunking' may focus more on the scientific aspects rather than family-friendly fun. 'Adventures for Men' may cater to a male audience rather than families. 'Mud Magazine' seems more focused on mud-related content, which doesn't align with the family-friendly, outdoor adventure theme of the article.
4. A large geographic area characterized by similar climate, plants, and animals is called a:
- A. Population
- B. Community
- C. Biome
- D. Ecosystem
Correct answer: C
Rationale: A) Population refers to a group of individuals of the same species living in a specific area. B) Community refers to all the populations of different species living and interacting in a particular area. C) Biome is a large geographic area characterized by similar climate, plants, and animals. Biomes are defined by factors such as temperature, precipitation, and vegetation types. D) Ecosystem refers to a community of living organisms interacting with each other and their physical environment. An ecosystem can be part of a biome.
5. What describes a cell’s reaction to being placed in a hypertonic solution?
- A. The cell will shrink as water is pulled out of the cell to equalize the concentrations inside and outside of the cell.
- B. The cell will swell as water is pulled into the cell to equalize the concentrations inside and outside of the cell.
- C. The cell will remain the same size since the concentrations inside and outside the cell are equal to begin with.
- D. The pH inside the cell will drop in order to equalize the pH inside and outside the cell.
Correct answer: A
Rationale: A cell placed in a hypertonic solution has a higher solute concentration outside the cell compared to inside. This creates a concentration gradient that causes water to move out of the cell through osmosis to equalize the concentrations on both sides. As a result, the cell will shrink or undergo plasmolysis, as water is pulled out of the cell. Choice B is incorrect because a hypertonic solution causes water to move out of the cell, leading to shrinkage rather than swelling. Choice C is incorrect as a hypertonic solution results in a concentration gradient that leads to water leaving the cell, causing it to shrink. Choice D is incorrect because pH is not directly affected by being placed in a hypertonic solution; the change in solute concentration primarily impacts water movement.
