Which of the following stages of mitosis is correctly paired with the events of that stage?
Which of the following stages of mitosis is correctly paired with the events of that stage? Anaphase — Centromeres of chromatid pairs separate and daughter chromosomes are pulled to opposite ends of the cell.
How would a decrease in the concentration of oxygen in the lungs affect the diffusion of oxygen in the blood?
How would a decrease of oxygen in the lungs affect the diffusion of oxygen into the blood? Diffusion is driven by concentration gradient. Thus oxygen would diffuse more slowly into the blood.
Which type of integral protein allows water and small ions to pass through the cell membrane?
Channel proteins, gated channel proteins, and carrier proteins are three types of transport proteins that are involved in facilitated diffusion. A channel protein, a type of transport protein, acts like a pore in the membrane that lets water molecules or small ions through quickly.
Which statement is correct about cytoplasm and Cytosol?
Which statement correctly distinguishes between cytoplasm and cytosol? Cytosol is the intracellular fluid and is composed of nutrients, ions, proteins, and waste, and cytoplasm is a term for all material located between the cell membrane and nucleus.
Which of the following correctly indicates the order in which mitosis occurs?
Anaphase → Metaphase → Prophase →Telophase →Interphase.
What is so special about osmosis compared with diffusion quizlet?
What is so special about osmosis, compared with diffusion? Osmosis is the movement of water rather than solute. In osmosis, water flows across a membrane toward the solution that has a higher concentration of solutes, because that is where water concentration is lower.
Why does alveolar air have less o2 compared with inhaled air?
Recall that the respiratory system works to humidify incoming air, thereby causing the air present in the alveoli to have a greater amount of water vapor than atmospheric air. In addition, alveolar air contains a greater amount of carbon dioxide and less oxygen than atmospheric air.
What does the presence of many mitochondria imply about a cells energy requirements quizlet?
What does the presence of many mitochondria imply about a cell’s energy requirements? Mitochondria produce energy, in the form of ATP molecules, for the cell. A large number of mitochondria in a cell indicates a high demand for energy.
