    What are the role of mitochondria?

    • Stores water

    • Converts food to energy

    • Jelly-like goo in cell

    • Makes food using sunlight

    Correct Answer
    A. Converts food to energy
    Explanation
    Mitochondria are organelles found in cells that play a crucial role in energy production. They are often referred to as the "powerhouses" of the cell because they convert nutrients from food into a form of energy called ATP (adenosine triphosphate) through a process called cellular respiration. This energy is then used by the cell to carry out various functions and processes necessary for survival. Therefore, the statement "Converts food to energy" accurately describes the role of mitochondria.

    In an isotonic solution, which direction is the flow of osmosis going to go?

    • Left

    • Right

    • Stay the same

    • Both directions

    Correct Answer
    A. Both directions
    Explanation
    In an isotonic solution, the concentration of solutes is the same inside and outside the cell. This means that there is no net movement of water molecules across the cell membrane, resulting in an equal flow of osmosis in both directions. Therefore, the flow of osmosis will go in both directions in an isotonic solution.

    Which is not an example of active transport?

    • Sodium-potassium pumps

    • Endocytosis

    • Osmosis

    • Exocytosis

    Correct Answer
    A. Osmosis
    Explanation
    Osmosis is not an example of active transport because it is a passive process that does not require energy expenditure by the cell. Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. In contrast, active transport processes such as sodium-potassium pumps, endocytosis, and exocytosis require the cell to expend energy in order to transport molecules or particles against their concentration gradient.

    Which characteristic of life listed here does a virus not have?

    • Heredity

    • Responsiveness

    • Metabolism

    • Reproduction

    Correct Answer
    A. Metabolism
    Explanation
    A virus does not have metabolism. Metabolism refers to the chemical processes that occur within an organism to maintain life. Unlike living organisms, viruses do not possess the machinery necessary for metabolic activities. They rely on host cells to reproduce and carry out essential functions, making them dependent on the host's metabolism. Therefore, while viruses can exhibit characteristics like heredity, responsiveness, and reproduction, they lack the ability to carry out metabolic processes independently.

    In a hypotonic solution inside of the cell to a hypertonic solution outside of the cell, which direction is the flow of osmosis going to go?

    • Left

    • Right

    • Stay the same

    • Both directions

    Correct Answer
    A. Right
    Explanation
    In a hypotonic solution inside the cell to a hypertonic solution outside the cell, the flow of osmosis is going to go from the hypotonic solution to the hypertonic solution. This is because osmosis is the movement of water molecules from an area of lower solute concentration (hypotonic) to an area of higher solute concentration (hypertonic) through a selectively permeable membrane. Therefore, the water molecules will move from the hypotonic solution inside the cell to the hypertonic solution outside the cell in order to equalize the solute concentration on both sides of the membrane.

  • 20. 

    Why does active transport occur?

    • The substance is moving with the concentration gradient

    • The substance is moving away the concentration gradient

    • The substance is moving against the concentration gradient

    • The substance is not moving

    Correct Answer
    A. The substance is moving against the concentration gradient
    Explanation
    Active transport occurs when a substance is moved against its concentration gradient. This means that the substance is being transported from an area of lower concentration to an area of higher concentration. This process requires the use of energy, usually in the form of ATP, to pump the substance across the cell membrane. Active transport is important for maintaining proper concentrations of ions and molecules inside and outside of cells, and it allows cells to accumulate substances that are needed in higher concentrations than what is available in their environment.

    Rate this question:

  • 21. 

    If a substance travels to a place of low concentration inside a cell to a place of high concentration outside of a cell, what type of transport happens?

    • Passive

    • Active

    • Osmosis

    • Diffusion

    Correct Answer
    A. Active
    Explanation
    Active transport occurs when a substance moves from an area of low concentration to an area of high concentration, which is the opposite of passive transport. This process requires the input of energy in the form of ATP to move molecules against their concentration gradient. Therefore, the correct answer is active transport.

    Rate this question:

  • 22. 

    Which is not an example of passive transport?

    • Osmosis

    • Facilitated diffusion

    • Ion channel

    • Endocytosis

    Correct Answer
    A. Endocytosis
    Explanation
    Endocytosis is not an example of passive transport because it requires energy in the form of ATP to transport molecules or particles into the cell. Passive transport, on the other hand, does not require energy and occurs spontaneously down a concentration gradient. Osmosis, facilitated diffusion, and ion channels are all examples of passive transport as they involve the movement of molecules or ions across a membrane without the need for energy input.
