Which of the following explains why oranges are available. If you say something, I ll ask someone at what age erectile dysfunction starts to clean it up. Though water is a polar molecule, it can also diffuse through the plasma membrane. If you forget it there is no way for StudyStack The molecules move from a region of higher concentration to a region of lower concentration until the concentration becomes equal . AP human test | Geography Quiz - Quizizz One and a Half Century of Diffusion: Fick, Einstein, before and beyond. are in the same box the next time you log in. Which of the following solutions will cause a red blood cell to shrink? Na+. movement of molecules from an area of high concentration to an area of low concentration Which of the following is most likely to move through the cell membrane by facilitated diffusion? Solution A and solution B are separated by a semipermeable membrane. Which of the following best explains the significance of a similarity among locations where olives, figs, grapes and lemons are grown? To move substances against a concentration or electrochemical gradient, a cell must use energy. Simple diffusion and osmosis do not involve transport proteins. O To edit the mRNA strand and make it ready to leave the nucleus. Which of the following best explains diffusion? Which of the following best describes the differences in the agricultural practices and land use for these products? Between 1950 and 1990, wheat production in India in average pounds per acre more than tripled, which allowed India to meet its populations need for food. If you've accidentally put the card in the wrong box, just tap on the card to take it out of the box. The electrochemical gradients set up by primary active transport store energy, which can be released as the ions move back down their gradients. The material that diffuses could be a solid, liquid or gas. She consumed a large amount of water in a short time (Don't try thiswater intoxication is often fatal.). A cell is isotonic to the surrounding 4% dextrose solution. His feet and legs were swollen with fluid. Never needs the presence of any other molecule C. Diffusion of every molecule is dependent on its concentration gradient and independent of the concentration of other molecular species in the medium D. All of the above, 2. A substance moves by facilitated diffusion into a cell. Does it move differently in the hot water than the cold water? Which of the following is not required for osmosis to occur? The SER detoxifies drugs and harmful substances ingested by and produced in the body. During the Green Revolution, agricultural practices from more developed countries diffused to less developed countries in Asia and Africa. Water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. While this could be facilitated by other molecules, it does not directly involve high-energy molecules such as adenosine triphosphate (ATP) or guanosine triphosphate (GTP). Privacy Policy and At the exact same time, add 2-3 drops off food coloring into each glass. Which of the following best explains the economic advantage of the type of farm-produced goods shown in the images? Which of the following explains the prevalence of banana plantations in Central America? this is in relation to the electrochemical gradient section. In secondary active transport, the two molecules being transported may move either in the same direction (i.e., both into the cell), or in opposite directions (i.e., one into and one out of the cell).
