Osmosis GIZMO Vocab Latest 2023 Rated A

Osmosis GIZMO Vocab Latest 2023 Rated A The cell membrane consists of a semipermeable _____ bilayer that surrounds a cell and regulates what enters and leaves the cell, allowing the cell to maintain homeostasis. phospholipid _____ comes from the Greek words for "same" and "steady," and refers to any process that living things use to actively maintain fairly stable internal conditions necessary for survival, despite changes in the external environment. For example, if the temperature outside drops significantly, your body may respond by triggering your muscles to contract and relax quickly, causing you to shiver. The shivering actually produces valuable heat that keeps your body warm, despite the cold temperatures of the surroundings. homeostasis The _____ _____ of a solution is the measure of how much solute is dissolved in a solvent, reported as a percent. It can be mathematically determined by dividing the number of solute particles by the total number of molecules in in the mixture (solute + solvent), multiplied by 100. Solute Concentration _____ _____ is the spontaneous net movement of ANY kind of particles through the semipermeable membrane of a cell from an area of higher concentration to an area of lower concentration until equilibrium is reached. Cellular Diffusion In general, _____ refers to the eventual spreading out of fluid (liquid and gas) particles in any 3-D space due to their constant, random motion (called Brownian motion). _____ involves the net movement of a substance (e.g., an atom, ion or molecule) down a concentration gradient from a region of high concentration to a region of low concentration. Examples of _____ include the spread of food coloring in a glass of water and the spread of air freshener through a room. (ONE TERM, SAME TERM IN ALL BLANKS) diffusion A state of being in equal balance despite a continual exchange of matter or energy. Two solutions are said to be in _____ _____ when particles continue to move back and forth between the two solutions, but the concentration of each solution remains roughly constant. dynamic equilibrium _____ is the spontaneous net movement of SOLVENT molecules (usually water) across a semipermeable membrane from an area of higher solvent/lower solute concentration to an area of lower solvent/higher solute concentration until dynamic equilibrium is reached. Osmosis A _____ membrane is a membrane that allows certain substances to pass through but does not allow the passage of other materials. semipermeable The _____ of a solution is the substance that is dissolved in in the solvent. In a solution, the _____ makes up the lesser part of the solution. (ONE WORD, SAME TERM IN BOTH BLANKS) solute Salt water is a solution in which salt is dissolved in water. Thus, the solute is _____ and the solvent is _____. (TWO TERMS, ORDER MATTERS) salt, water The _____ of a solution is a liquid or gas in which another substance--the solute--is dissolved. The _____ makes up the greater part of a solution. (ONE WORD, SAME TERM IN BOTH BLANKS) solvent The _____ _____ of a solution can be mathematically determined by dividing the number of solvent particles by the total number of particles in in the mixture (solute + solvent), multiplied by 100. solvent concentration During osmosis, solvent particles (usually water molecules) move across the cell membrane from an area of _____ concentration to an area of _____ concentration. (TWO TERMS, ORDER MATTERS) higher, lower During osmosis, when there is a HIGHER concentration of solvent particles INSIDE the cell, there will be a net flow of solvent particles moving _____ of the cell, and the cell will _____. (TWO TERMS, ORDER MATTERS) out, shrink During osmosis, when there is a LOWER concentration of solvent particles INSIDE the cell, there will be a net flow of solvent particles moving _____ the cell, and the cell will _____. (TWO TERMS, ORDER MATTERS) into, expand During osmosis, solute particles cannot move into or out of the cell. However, solvent particles (usually water molecules) CAN move into and out of the cell. If the concentration of SOLUTE particles is higher INSIDE the cell than outside the cell, there will be a net flow of SOLVENT particles flowing _____ the cell, which will gardually lower the solute concentration and cause the cell to _____. (TWO TERMS, ORDER MATTERS) into, expand What substance is called the "universal solvent?" water If 20 solvent particles flow out of a cell, and 15 solvent particles flow into a cell, then the _____ flow of solvent particles is 5 solvent particles out of the cell. net In the image, water is the solvent and glucose is the solute. During osmosis, the net flow of water will be from _____. (COMPLETE THE SENTENCE USING THE PHRASE "right to left" OR "left to right") left to right In this image, the _____ molecules are the solute patricles. sucrose
