This process requires some form of chemical energy. What process permits absorption of glucose into cells? As a result of the EUs General Data Protection Regulation (GDPR). Which of the following best explains diffusion? A number of colonies were established and settled by people from Great Britain. Terms of Service. are in the same box the next time you log in. By osmosis: water will move from solution A to solution B. Which of the following best explains the Green Revolution's highly variable level of success in increasing agricultu. Even though this is random non-directed movement, with a large bulk, it can create a scenario where there is no net movement of gas from the container. This voltage will be maintained as long as K, For more explanation of how the voltage across the membrane is established, take a look at the. A. This way, the capillaries remain at a low carbon dioxide concentration, allowing the constant movement of the molecule away from cells. Epinephrine binds to a cell-surface receptor; the activated receptor catalyzes the conversion of glycogen to glucose. Process of Osmosis vs. Diffusion . ; Diffusion occurs in liquids and gases when their particles collide randomly and . Na+/K+ pump. Irrigation increases the salt content of the soil, which disrupts the growth of crops and degrades soil fertility. If sublimation is carried out in a narrow crucible, the fumes diffuse slowly out towards the mouth of the container and then rapidly disappear. a.QH=500kW,QC=100kWb.QH=500kW,Wcycle=250kW,QC=200kWc.Wcycle=350kW,QC=150kWd.QH=500kW,QC=200kW\begin{array}{l}{\text { a. } The passive process that involves the movement of water through aquaporins is ________. Which of the following explains one of the negative consequences of the Green Revolution that would be of greater c, Runoff of agricultural chemicals into the local groundwater that pollutes water resources. In any system, molecules are moving with a certain amount of kinetic energy. 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? For instance, in the example about the diffusion of iodine gas, if the crucible is placed in another closed container and iodine crystals are heated for an extended period of time, the rate at which the purple gas seems to disappear at the mouth of the crucible will reduce. A Diffusion provides encryption strength, while confusion provides data integrity B. Diffusion provides function integrity, while confusion provides encryption confidentiality. fats and proteins yield too much energy for the cells to process. Limited farmland encourages intensive farming with intercropping to produce high yields. The conversion from manual thread spinning to an industrial processing approach led to increased demand for raw cotton in the agricultural sector. Domestication of plants and animals evolved in each hearth independently of one another as societies in each area learned and applied the process to local plants and animals. Divide the following terms into component parts and give the meanings of the complete terms. Image 2 shows an innovation that occurred in the Second Agricultural Revolution, reducing the amount of labor needed and increasing crop yields. When you've placed seven or more cards in the Don't know box, tap "retry" to try those cards again. His feet and legs were swollen with fluid. The greater the surface area, the faster the rate of diffusion. John David Jackson, Patricia Meglich, Robert Mathis, Sean Valentine, Charles Welsh, Cynthia Prentice-Craver, David Shier, Jackie Butler, Ricki Lewis, Child Psychopathology - Ch 1 Review questions. She consumed a large amount of water in a short time (Don't try thiswater intoxication is often fatal.). he Na+\mathrm{Na}^{+}Na+concentration of a solution was determined by measurement with a sodium ion-selective electrode. Comparing the two images, which survey system was more efficient in terms of trade? The Green Revolution led to an increase in food production in many places around the world, but there have been some negative consequences. In the case of a cell, positive and negative charges are separated by the barrier of the cell membrane, with the inside of the cell having extra negative charges relative to the outside. How, exactly, does the sodium-potassium pump establish a voltage across the membrane? Invention of the plow eased the intensive use of labor, and the innovation of mechanized farm equipment led to improved food production. Which of the following best explains how a wheat farmer in the Northern Plains region of the United States is able to maximize profits? answer choices The English language initially diffused to North America through the process of relocation diffusion. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells. Which of the following organelles will be abundant in liver cells? As an example, let's suppose we have a high concentration of sodium ions in the extracellular space (thanks to the hard work of the sodium-potassium pump). Township and range: unit-block field patterns with dispersed farmsteads and occasional villages. Carbon dioxide would diffuse faster than bromine gas C. Integral membrane proteins that facilitate diffusion are highly specific about their cargo D. All of the above, Biologydictionary.net Editors. Solution A contains 1% glucose, solution B contains 5% glucose. If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until . Which of the following solutions contains the most solute? Answer: Random movement of molecules is not fast enough to disperse through the larger eukaryotic cell volume, Explanation: Eukaryotic clels are much bigger than prokaryotic cells. Water moves into and out of cells by osmosis. Biology Dictionary. Use these flashcards to help memorize information. In each cycle, three sodium ions exit the cell, while two potassium ions enter. In the South Asian country of Sri Lanka, tea is farmed as a monoculture. Water leaves the cells and the cells shrink. He should be given a hypotonic drip to draw fluid out of his cells. With the phosphate group gone, the pump will change back to its original form, opening towards the interior of the cell. The SER detoxifies drugs and harmful substances ingested by and produced in the body. A. One and a Half Century of Diffusion: Fick, Einstein, before and beyond. Which of the following best explains diffusion? The rate of this movement depends on the energy of the . You would need to create a new account.

Secondary active transport involves the movement of a substance into a cell with its concentration gradient. Simple diagram of a symporter (carrying two molecules in the same direction) and an antiporter (carrying two molecules in opposite directions). If the cell is moved to a 6% dextrose solution, then predict what will happen to the cell. Passive transport is a way that small molecules or ions move across the cell membrane without input of energy by the cell. What organelle degrades old, worn-out organelles and cell components? Most lettuce is produced, processed, and packaged for sale in supermarkets that are a significant distance from where the product was grown. A process that requires energy to move a substance against its concentration gradient is called: The Na+/K+ pump transports three sodium ions out of the cell for every two potassium ions moved into the cell.
