Solution The correct options are BIt can only transport water over short distancesCA semipermeable membrane is requiredOsmosis describes the diffusion of the solvent through a semipermeable membrane. Water, the usual solvent in biological systems, migrates from the region of its higher concentration to the region of its lower concentration. The process is generally slow and can only transport water over short distances.Scheduled maintenance: Saturday, September 10 from 11PM to 12AM PDT

Osmosis is the
diffusion of water from a region of lower water concentration to a region of higher water concentration. The presence of aquaporins (proteins that form water channels in the membrane) should speed up the process of osmosis. Select the correct statement about osmosis. Osmosis is the diffusion of water molecules across a selectively permeable membrane. Osmosis is the diffusion of water molecules across a selectively permeable membrane. What name is given to the process by which water crosses a selectively permeable membrane? osmosis Endocytosis moves materials _____ a cell via _____. into ... membranous vesicles You can recognize the process of pinocytosis when _____. the cell is engulfing extracellular fluid A white blood cell engulfing a bacterium is an example of _____. phagocytosis Which statements about the fluid mosaic structure of a membrane are correct? Select the three correct statements. -Membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer. 2,3,4 Which of the following would be a factor that determines whether the molecule selectively enters the target cells? the nonpolar, hydrophobic nature of the drug
molecule the similarity of the drug molecule to other molecules that are transported into the target cells Which of the following factors does not affect membrane permeability? The polarity of membrane phospholipids The polarity of membrane phospholipids How can a lipid be distinguished from a sugar? Lipids are mostly nonpolar. True or false? Osmosis is a type of diffusion. True What property of dishwashing liquid (detergent) makes it useful to wash grease from pans? Amphipathic nature Which of the following particles could diffuse easily through a cell membrane? Oxygen (O2) Oxygen (O2) True or false? The water-soluble portion of a phospholipid is the polar head, which generally consists of a glycerol molecule linked to a phosphate group. True If a red blood cell is placed in a salt solution and bursts, what is the tonicity of the solution relative to the interior of the cell? Hypotonic If the concentration of phosphate in the cytosol is higher than the concentration of phosphate in the surrounding fluid, how could the cell increase the concentration of phosphate in the cytosol? active transport What happens when two solutions separated by a selectively permeable membrane reach osmotic equilibrium? Water molecules move between the two solutions, but there is no net movement of water across the membrane. Which of the following statements about a typical plasma membrane is correct? The two sides of the plasma membrane have different lipid and protein composition. The two sides of the plasma membrane have different lipid and protein composition. Part A a fluid structure in which phospholipids and proteins move freely between sides of the membrane two layers of phospholipids with proteins either crossing the layers or on the surface of the layers The permeability of a biological membrane to a specific polar solute may depend on which of the following? the types of transport proteins in the membrane Which of the following correctly describes some aspect of exocytosis or endocytosis? Both processes provide a mechanism for exchanging membrane-impermeable molecules between the organelles and the cytosol. Exocytosis and endocytosis temporarily change the surface area of the plasma membrane. Which statement is correct? A solution of seawater is hypertonic. The contents of a red blood cell are hyperosmotic to distilled water. Recommended textbook solutionsAnatomy And Physiology Coloring Workbook12th EditionElaine Nicpon Marieb 922 solutions

It occurs only in plants. In osmosis, the diffusion of water molecules takes place from a solution of higher concentration to a solution of lower concentration through a semi-permeable membrane. Thus, a concentration gradient should be present for the osmosis to happen.
Which of the following happens during osmosis?Key Concepts. Osmosis is the transport of a solvent through a semipermeable membrane that separates two solutions of differing solute concentration. During osmosis, the solvent moves from the solution that is lower in solute concentration to the solution that is higher in solute concentration.
What is true about osmosis and diffusion?Both osmosis and diffusion equalize the concentration of two solutions. Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration.
Which of the following statements hold true for both diffusion and osmosis?Answer. Explanation:A) both diffusion and osmosis does not need energy.
