    A process that requires oxygen is said to be?

    • Photosynthesis

    • Aerobic

    • Anaerobic

    • Cellular Division

    • Fish

    Correct Answer
    A. Aerobic
    Explanation
    A process that requires oxygen is said to be aerobic because aerobic processes rely on the presence of oxygen to produce energy. In these processes, oxygen is used as the final electron acceptor in the electron transport chain, allowing for the efficient production of ATP through cellular respiration. This is in contrast to anaerobic processes, which do not require oxygen and can still produce ATP through alternative pathways such as fermentation.

    An energy producing process that needs glucose and oxygen

    • Photosynthesis

    • Chemosynthesis

    • Digestion

    • Cell Death

    • Cellular Respiration

    Correct Answer
    A. Cellular Respiration
    Explanation
    Cellular respiration is the correct answer because it is the energy-producing process that requires both glucose and oxygen. During cellular respiration, glucose is broken down in the presence of oxygen to produce ATP, the energy currency of cells. This process occurs in the mitochondria of cells and is essential for the production of energy needed for various cellular activities. Photosynthesis, on the other hand, is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen. Chemosynthesis is a process in which organisms obtain energy from inorganic compounds. Digestion is the process of breaking down food into smaller molecules for absorption. Cell death is the termination of a cell's biological functions.

    Someone farts in a far corner of the room.  People on that side smell it early, but you don't smell it until later, this is an example of..

    • Osmosis

    • Air currents

    • Endocytosis

    • Diffusion

    • Passive Transport

    Correct Answer
    A. Diffusion
    Explanation
    Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In this scenario, the fart molecules disperse into the air and spread out, creating a higher concentration in the corner of the room where it occurred. As time passes, the molecules continue to spread out and eventually reach your side of the room, resulting in you smelling it later. This is a clear example of diffusion, where the molecules move to equalize the concentration throughout the room.

    When the cell membrane envelopes large particles and injects them into the cytoplasm of the cell.

    • Exocytosis

    • Facillitated Diffusion

    • Carrier Protein

    • Endocytosis

    • Passive Transport

    Correct Answer
    A. Endocytosis
    Explanation
    Endocytosis is the process by which the cell membrane engulfs large particles and brings them into the cytoplasm of the cell. This can occur through various forms of endocytosis such as phagocytosis (engulfing solid particles) or pinocytosis (engulfing liquid particles). In this process, the cell membrane forms a vesicle around the particle and then internalizes it into the cell. Endocytosis is an active process that requires energy and is used by cells to take in nutrients, remove waste, and regulate the composition of the extracellular environment.

    Getting rid of waste products in a cell

    • Endocytosis

    • Lysosome

    • Exocytosis

    • Golgi Apparatus

    • None of the above

    Correct Answer
    A. Exocytosis
    Explanation
    Exocytosis is the correct answer because it is the process by which waste products or other substances are expelled from a cell. During exocytosis, vesicles containing the waste products fuse with the cell membrane and release their contents outside of the cell. This process is important for maintaining cellular homeostasis and removing waste materials that could be harmful if accumulated inside the cell. Endocytosis, lysosomes, and the Golgi apparatus are not directly involved in the elimination of waste products from the cell.

    A water molecule diffuses across a semi permeable membrane, this is an example of

    • Diffusion

    • Facilitated Diffusion

    • Active Transport

    • Osmosis

    • Sclerosis

    Correct Answer
    A. Osmosis
    Explanation
    When a water molecule diffuses across a semi-permeable membrane, it is an example of osmosis. Osmosis is the process by which solvent molecules, in this case, water, move from an area of higher concentration to an area of lower concentration through a semi-permeable membrane. In this scenario, the water molecule is moving from an area of lower solute concentration to an area of higher solute concentration, equalizing the concentrations on both sides of the membrane. This movement of water molecules is driven by the concentration gradient and does not require any energy input.

    Rate this question:

  • 14. 

    Substance diffuses across a membrane without energy but with a carrier protein, what process?

    • Facilitated Diffusion

    • Passive Transport

    • Active Transport

    • Osmosis

    • None of the above

    Correct Answer
    A. Facilitated Diffusion
    Explanation
    Facilitated diffusion is a passive transport process where substances move across a biological membrane with the help of carrier proteins. It occurs when specific molecules, typically larger or polar ones, bind to carrier proteins and are transported from areas of higher concentration to lower concentration without the need for energy input. This process is essential for the movement of certain molecules that cannot easily pass through the lipid bilayer of the membrane on their own.

    • Digestion

    • Cellular Respiration

    • Photosynthesis

    • DNA replication

    • Protein Synthesis

    Correct Answer
    A. Photosynthesis
    Explanation
    Photosynthesis is the process by which plants convert sunlight into energy, specifically in the thylakoid membranes of their cells. During photosynthesis, chlorophyll molecules in the thylakoid membranes capture light energy, which is then used to convert carbon dioxide and water into glucose and oxygen. This process is crucial for plant growth and survival, as it provides them with the energy they need to carry out other cellular processes. Therefore, the correct answer is photosynthesis.

    Rate this question:

    Allows gas exchange in a plant and is vital for photosynthesis and cellular respiration.

    • Guard Cell

    • Epidermal Cell

    • Cell Wall

    • Stomate

    • Plasma Membrane

    Correct Answer
    A. Stomate
    Explanation
    Stomates are tiny openings found on the surface of plant leaves that allow for gas exchange. They play a vital role in photosynthesis, as they allow carbon dioxide to enter the leaf and oxygen to exit. Stomates also help regulate the water balance of the plant by controlling the loss of water vapor through transpiration. Guard cells surround each stomate and can open or close the pore depending on the plant's needs. Therefore, the stomate is the correct answer as it allows for gas exchange and is essential for both photosynthesis and cellular respiration.

    Correct Answer
    A. Animal Cell
    Explanation
    An animal cell is the correct answer because it undergoes cellular respiration, has centrioles, and a nucleus. Cellular respiration is the process by which cells convert glucose into energy, and animal cells perform this process. Centrioles are organelles involved in cell division, and animal cells have them while plant cells do not. The nucleus is the control center of the cell, containing the genetic material, and both animal and plant cells have a nucleus. Therefore, the characteristics listed in the question align with those of an animal cell.

    Rate this question:

  • 19. 

    Large Vacuole and an absence of lysosomes

    • Plant Cell

    • Animal Cell

    • Neither

    Correct Answer
    A. Plant Cell
    Explanation
    The presence of a large vacuole and an absence of lysosomes indicates that the cell is a plant cell. Plant cells typically have a large central vacuole that occupies most of the cell's volume, whereas animal cells have smaller vacuoles or none at all. Lysosomes, on the other hand, are membrane-bound organelles that contain digestive enzymes and are commonly found in animal cells to break down waste and cellular debris. Therefore, the combination of a large vacuole and no lysosomes points to the cell being a plant cell.

    • Hydrophobic molecule

    • Oxygen

    • Sugar

    • Water

    • Carbon dioxide

    Correct Answer
    A. Sugar
    Explanation
    The cell membrane is selectively permeable, meaning it allows certain molecules to pass through while restricting others. Hydrophobic molecules, such as oxygen and carbon dioxide, can easily pass through the cell membrane due to their ability to dissolve in the lipid bilayer. However, sugar molecules are hydrophilic (water-loving) and cannot pass through the hydrophobic interior of the cell membrane. Therefore, sugar cannot pass across the cell membrane.

    Rate this question:

  • 35. 

    What molecules can pass through the cell membrane?

    • Sugar

    • Fructose

    • H+

    • Hydrocarbons

    • None of the above

    Correct Answer
    A. Hydrocarbons
    Explanation
    Hydrocarbons can pass through the cell membrane because they are nonpolar molecules. The cell membrane is composed of a lipid bilayer, which is also nonpolar. Nonpolar molecules can easily diffuse across the cell membrane through passive transport, without the need for any specific transport proteins. In contrast, sugar, fructose, and H+ ions are polar or charged molecules, which cannot easily pass through the nonpolar cell membrane. Therefore, the correct answer is hydrocarbons.

    Correct Answer
    A. Concentration gradient
    Explanation
    This scenario of the Titanic hitting an iceberg and everyone eventually heading into the water is an example of a concentration gradient. A concentration gradient refers to a difference in the concentration of a substance between two areas. In this case, the concentration of people on board the ship is high, while the concentration of people in the water is initially low. As a result, people start moving from an area of high concentration (the ship) to an area of low concentration (the water) until the concentrations become more balanced. This movement of people is driven by the concentration gradient.

    • Facilitated osmosis

    • Dilluted exocytosis

    • Endocrine equilibrium

    • Facilitated diffusion

    Correct Answer
    A. Facilitated diffusion
    Explanation
    Facilitated diffusion is the process in which molecules or ions are transported across the cell membrane with the help of carrier proteins. These carrier proteins bind to specific molecules and undergo a conformational change to transport them across the membrane. This process does not require energy and allows for the movement of molecules down their concentration gradient. Therefore, facilitated diffusion is the correct answer as it accurately describes the process of diffusion with the assistance of carrier proteins.

    If there is more water outside the cell and it moves into the cell this is an example of

    • Isotonic solution

    • Hypotonic solution

    • Hypertonic solution

    Correct Answer
    A. Hypotonic solution
    Explanation
    When there is more water outside the cell and it moves into the cell, it indicates that the concentration of solutes is higher inside the cell compared to outside. This causes water to move from an area of higher concentration (outside the cell) to an area of lower concentration (inside the cell) in order to equalize the solute concentrations. This scenario is characteristic of a hypotonic solution.

    Shriveled cells may be the result of this kind of solution

    • Isotonic

    • Hypertonic

    • Hypotonic

    • Mesotronic

    Correct Answer
    A. Hypertonic
    Explanation
    When a solution is hypertonic, it means that it has a higher concentration of solutes compared to the cells. In this case, when cells are exposed to a hypertonic solution, water will move out of the cells through osmosis, causing the cells to lose water and shrink or shrivel.

    Isotonic solution means...

    • Same amount of water inside and outside

    • More water outside

    • More solvent inside

    • Less solvent inside

    • Less water outside

    Correct Answer
    A. Same amount of water inside and outside
    Explanation
    An isotonic solution refers to a solution where the concentration of solutes is equal both inside and outside the cell. This means that there is an equal amount of water inside and outside the cell, resulting in no net movement of water across the cell membrane. In an isotonic solution, the cell maintains its normal shape and size as there is no osmotic pressure acting on it.
