    ____ solution causes a cell to shrink because of osmosis.

    Correct Answer
    Hypertonic
    Explanation
    A hypertonic solution causes a cell to shrink because of osmosis. In a hypertonic solution, the concentration of solutes outside the cell is higher than inside the cell. As a result, water molecules move out of the cell to the area of higher solute concentration, causing the cell to lose water and shrink. This occurs because water moves from an area of lower solute concentration (inside the cell) to an area of higher solute concentration (outside the cell) in order to equalize the solute concentration on both sides of the cell membrane.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because there are indeed two main types of endocytosis based on the type of materials that are taken into the cell. These two types are phagocytosis and pinocytosis. Phagocytosis is the process by which solid particles are engulfed by the cell, while pinocytosis is the process by which liquid or dissolved substances are taken in. Therefore, the correct answer is true.

  • 5. 

    ____ is the movement of a substance by a vesicle to the outside of a cell.

    Correct Answer
    Exocytosis
    Explanation
    Exocytosis is the process by which substances are transported out of a cell through the fusion of vesicles with the cell membrane. During exocytosis, the vesicle containing the substance fuses with the plasma membrane and releases its contents into the extracellular space. This mechanism is essential for the secretion of molecules such as hormones, neurotransmitters, and digestive enzymes. It allows the cell to communicate with its surroundings and export materials to be used by other cells or tissues.

  • 6. 

    Phagocytosis is used in animal cells to ingest bacteria and viruses that invaded the body. These cells are known as _____.

    Correct Answer
    phagocytes
    Explanation
    Phagocytosis is a process in which cells engulf and digest foreign particles such as bacteria and viruses. The cells that perform this function are called phagocytes. They play a crucial role in the immune response by identifying and eliminating pathogens that have entered the body. Phagocytes include various types of white blood cells, such as macrophages and neutrophils. These cells have specialized receptors that recognize and bind to the foreign particles, triggering the process of phagocytosis. Once engulfed, the phagocytes break down the pathogens using enzymes and destroy them, helping to protect the body from infections.

    What name is given to osmosis condition of the blood cell in the second image (middle) of three?

    • Isotonic

    • Hypertonic

    • Hypotonic

    • Pinocytosis

    • Diffusion

    Correct Answer
    A. Isotonic
    Explanation
    In the second image, the blood cell appears to be in an isotonic condition. This means that the concentration of solutes inside the cell is equal to the concentration of solutes outside the cell. As a result, there is no net movement of water across the cell membrane, and the cell maintains its shape and size.

    One example of active transport in animal cells involves a carrier protein known as the _____ -_____ pump. - ProProfs

    One example of active transport in animal cells involves a carrier protein known as the _____ -_____ pump.

    • ATP-Energy

    • Lithium-Sodium

    • Sodium-Potassium

    • Calcium-Potassium

    • ADP-ATP

    Correct Answer
    A. Sodium-Potassium
    Explanation
    Active transport is a process that requires energy to move molecules or ions against their concentration gradient. In animal cells, one example of active transport is the sodium-potassium pump. This pump uses ATP energy to actively transport three sodium ions out of the cell and two potassium ions into the cell. This process helps to maintain the concentration gradients of sodium and potassium across the cell membrane, which is important for various cellular functions such as nerve impulse transmission and muscle contraction.

    A vesicle is an organelle that fuses with lysosomes in order that contents can be digested.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    A vesicle is a small sac-like structure within a cell that transports and stores various substances. One of its important functions is to fuse with lysosomes, which are organelles responsible for digestion, so that the contents of the vesicle can be broken down and digested. This process allows the cell to obtain nutrients and recycle waste materials. Therefore, the statement that a vesicle fuses with lysosomes for digestion is true.

    There are two (2) main types of endocytosis based on the kind of material that is taken into a cell.  Which two are correct answers listed below?

    • Diffusion + Ion channels

    • Pinocytosis + Phagocytosis

    • Active Osmosis + Passive Transport

    • Phagocytosis + Passive Transport

    • Sodium-Potassium Pump + Iron-Sodium Pump

    Correct Answer
    A. Pinocytosis + Phagocytosis
    Explanation
    Pinocytosis and phagocytosis are the correct answers because they both involve the process of endocytosis, which is the uptake of materials into a cell by engulfing them with the cell membrane. Pinocytosis is the process of taking in small droplets of extracellular fluid, while phagocytosis is the process of engulfing and digesting solid particles or microorganisms. Both processes are important for the cell to obtain nutrients and remove waste materials.

    The movement of a substance down the substance's concentration gradient is called?

    Correct Answer
    diffusion
    Explanation
    Diffusion refers to the movement of a substance from an area of higher concentration to an area of lower concentration. It occurs naturally and does not require any external energy input. This process is driven by the random motion of particles and aims to achieve equilibrium by evenly distributing the substance throughout the available space. Diffusion is a fundamental process in various biological and physical systems, such as the exchange of gases in the lungs and the movement of molecules across cell membranes.

    • Isotonic

    • Hypertonic

    • Hypotonic

    • Pinocytosis

    • Diffusion

    Correct Answer
    A. Hypotonic
    Explanation
    The correct answer is "Hypotonic." In the first image of the three, the blood cell appears to be larger and more swollen compared to the surrounding solution. This suggests that the concentration of solutes outside the cell is lower than inside the cell, causing water to move into the cell by osmosis. This results in the cell expanding and becoming hypotonic.

  • 15. 

    Hypertonic solution causes a cell to swell because of osmosis.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    A hypertonic solution actually causes a cell to shrink or shrink because of osmosis. In a hypertonic solution, there is a higher concentration of solutes outside the cell compared to inside the cell. This creates a concentration gradient that causes water to move out of the cell, resulting in the cell shrinking.

    Rate this question:

    The pressure that water molecules exert against the cell wall is called _____ _____.

    Correct Answer
    turgor pressure
    Explanation
    Turgor pressure refers to the pressure exerted by water molecules against the cell wall. This pressure is crucial for maintaining the shape and rigidity of plant cells. When the plant cell is fully hydrated, the water molecules exert pressure against the cell wall, creating a turgid state. This pressure helps to support the plant structure and allows plants to stand upright. Turgor pressure also plays a role in various cellular processes, such as nutrient uptake and cell expansion.

    _____ - _____ _____ is an example of a cell membrane "pump".

    Correct Answer
    Sodium-potassium pump, Sodium potassium pump
    Explanation
    The Sodium-potassium pump is an example of a cell membrane "pump" that transports sodium and potassium ions across the cell membrane. It actively pumps three sodium ions out of the cell for every two potassium ions it brings into the cell, using ATP energy. This process is essential for maintaining the proper balance of sodium and potassium ions inside and outside the cell, which is crucial for various cellular functions such as nerve signal transmission and muscle contraction.
