Questions and Answers
  • 1. 

    A student is heating a solution of milk and digestive enzymes to 37C on a hot plate.  Which pieces of safety equipment should the student use?

    • A.

      fire extinguisher, aprons

    • B.

      Goggles, fire blanket

    • C.

      Heat-resistant gloves, eye wash station

    • D.

      Aprons, goggles, heat-resistant gloves

    Correct Answer
    D. Aprons, goggles, heat-resistant gloves
    Explanation
    The student should use aprons to protect their clothing from spills or splashes. Goggles should be worn to protect the eyes from any potential splashing or splattering of the solution. Heat-resistant gloves are necessary to protect the hands from burns or injuries while handling hot equipment or containers.

    Some students are investigating the similarities and differences between plant and animal cells. Which of the following sets of equipment would be MOST useful for this investigation?

    • A.

      Microscope and slides

    • B.

      Hand lens and razor blades

    • C.

      Microscope and graduated cylinder

    • D.

      Triple beam balance and microscope

    Correct Answer
    A. Microscope and slides
    Explanation
    A microscope and slides would be the most useful equipment for investigating the similarities and differences between plant and animal cells. A microscope allows students to observe the cells at a high magnification, enabling them to see the structures and organelles within the cells. Slides can be prepared with plant and animal cell samples, allowing for easy comparison and analysis. The other options, such as a hand lens and razor blades or a graduated cylinder, would not provide the necessary tools for examining cellular structures. A triple beam balance is used for measuring mass and would not be relevant to this investigation.

    The human body is a complex system. Which of the following are systems that are most directly required to make the human body move?

    • A.

      Muscle and skeletal systems

    • B.

      Circulatory and endocrine systems

    • C.

      Excretory and respiratory systems

    • D.

      Digestive and nervous systems

    Correct Answer
    A. Muscle and skeletal systems
    Explanation
    The human body requires the muscle and skeletal systems to make movement possible. The skeletal system provides a framework and support for the body, while the muscles allow for contraction and movement. These two systems work together to enable the body to perform various actions such as walking, running, and lifting objects. The circulatory and endocrine systems are responsible for transportation and regulation of hormones, the excretory and respiratory systems are involved in waste removal and gas exchange, and the digestive and nervous systems are responsible for digestion and communication, respectively. However, none of these systems are directly involved in the physical act of movement.

    Which of the following energy transformation systems would be most affected by changes inweather?

    • A.

      geothermal power generation

    • B.

      Natural gas power generation

    • C.

      Nuclear power generation

    • D.

      Wind turbine power generation

    Correct Answer
    D. Wind turbine power generation
    Explanation
    Wind turbine power generation would be most affected by changes in weather because wind is the primary source of energy for wind turbines. If the weather conditions are not favorable, such as low wind speeds or severe storms, the efficiency and effectiveness of wind turbines will be significantly reduced. In contrast, geothermal power generation relies on heat from the Earth's interior, natural gas power generation relies on burning natural gas, and nuclear power generation relies on nuclear reactions, all of which are not directly influenced by weather conditions.

    Roots of plants normally grow downward. Which of these stimuli is responsible for the normal plant root growth?

    • A.

      air

    • B.

      Gravity

    • C.

      Light

    • D.

      Water

    Correct Answer
    B. Gravity
    Explanation
    Gravity is responsible for the normal plant root growth. Gravity causes the root to grow in the downward direction, allowing the plant to anchor itself in the soil and absorb water and nutrients from the ground. This gravitational response is known as geotropism or gravitropism, and it is a crucial factor in the development and growth of plant roots.
