Which of these components add specialized functions to the plasma membrane? What is required for filtration to occur? C. rough endoplasmic reticulum does the glucose molecule just randomly attach itself to the protein when it's about to transport a sodium ion to the other side? Which of the following explains how global demand for palm oil has proved beneficial and detrimental f. Palm oil exports provided substantial corporate profits, but the growth in the industry resulted in heavy deforestation in both countries. Explain the components present in a phospholipid. Which of the following best explains diffusion? Which of the following best explains the spatial patterns illustrated in von Thnens model? C. peroxisome The phospholipid is a lipid molecule with a hydrophilic ("water-loving") head and two hydrophobic ("water-hating") tails. The rate of this movement depends on the energy of the . What values of a and b would complete each of the following (X and Y are not meant to be any particular elements): 266X+baY15aX+32b\begin{aligned} 266 \mathrm{X} & \rightarrow \alpha+\mathrm{b}^{\mathrm{a}} \mathrm{Y} \\ Which of the following is least likely to increase the rate of diffusion? We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Drought and depletion of groundwater sources in developing countries cause a rise in global grain prices and associated higher costs for food. Retrieved from https://biologydictionary.net/diffusion/. Adult should review each experiment and determine what the appropriate age is for the students participation in each activity before conducting any experiment. Since they are relatively large openings in the plasma membrane, these integral membrane proteins also have high specificity. A Diffusion provides encryption strength, while confusion provides data integrity B. Diffusion provides function integrity, while confusion provides encryption confidentiality. When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Large polar molecules cannot diffuse across a biological membrane B. The Diffusion of Oxygen, Carbon Dioxide, and Inert Gas in Flowing Blood. In this experiment, the food coloring that gets added is the same temperature in each of the hot and cold water tests. 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. C. Diffusion provides ciphertext heterogeneity, while confusion provides algorithm This problem has been solved! Which of the following best explains a negative economic consequence of the Green Revolution in less developed countries as compared to more developed countries? In general, to maintain homeostasis the relationship between our intracellular and extracellular fluids should be which of the following? Grocery stores sell oranges that are grown in locations with similar climates but different growing seasons. What process does water use to move across the plasma membrane? Direct link to l's post Questions: Its tempting to simply make an argument based on stoichiometry: for every three ions of sodium that move out, only two ions of potassium move in, resulting in a more negative cell interior. A. What conditions affect the diffusion of a substance in water? It is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration. But now you have two mixtures of different solute concentrations. Which of these statements about diffusion of molecules is true? Which of the following is not required for osmosis to occur? (2005). When they move in the same direction, the protein that transports them is called a. Which of the following explains an economic benefit of cattle production using feedlots rather than grass pastures? Which of the following scenarios best explains the Columbian Exchange? Which of the following best explains the farming practice related to plantation agriculture? What do you predict will happen to the person's cells? Do not mix or stir. Tea plantations were established in Sri Lanka by a former European colonial power. Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. In simple diffusion, this process proceeds without the aid of a transport protein. Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of lower concentration solution (i.e., higher concentration of water) to an area of higher concentration solution (i.e., lower concentration of water). Water moves into and out of cells by osmosis. Water leaves the cells and the cells shrink. In the South Asian country of Sri Lanka, tea is farmed as a monoculture. Use these flashcards to help memorize information. To extend the example given above, if the block of dry ice is broken into multiple pieces, the area that interacts with the atmosphere immediately increases. What will happen to a freshwater fish in the ocean? Diffusion is the movement when molecules move from higher concentrated area to lower concentrated area. Technological innovations, such as the devices shown in the images, and increased agricultural productivity led to better diets, longer life expectancies, and more people available for work in factories. Which of the following is the best situation for maintaining homeostasis? Question 16 30 seconds Q. Channels are very selective and will accept only one type of molecule (or a few closely related molecules) for transport. Which of the following explains the diffusion and successful cultivation of many plants and animals in new regions of the world through the Columbian Exchange? By what endocytosis process do some white blood cells engulf bacteria? Irrigation increases the salt content of the soil, which disrupts the growth of crops and degrades soil fertility. The cell membrane lets certain substances enter the cell and keeps certain substances out of the cell. This is usually not directed in any particular manner, and can appear random. One phosphate group from ATP is attached to the pump, which is then said to be phosphorylated. One of the most important pumps in animal cells is the, Not only does the sodium-potassium pump maintain correct concentrations of Na. Which of the following best explains why farmers would plant both strawberries and watermelons in the same field? D. The SER stores calcium ions. A. What separates the intracellular fluid from the extracellular fluid? A vesicle fuses with the plasma membrane and releases its contents to the extracellular fluid. Also, think about where you see this happen in other places. how does the carrier protein "harness" energy from another molecules concentration gradient? The plasma membrane is semipermeable, meaning that some things can enter the cell, and some things cannot. The brands listed above are trademarks of 3M. are in the same box the next time you log in. diffusion: [noun] the state of being spread out or transmitted especially by contact : the action of diffusing. Does it move differently in the hot water than the cold water? Which of the following best describes the impacts of the Second Agricultural Revolution? Be sure to clean up when you are done. After addition of 1.00mL1.00 \mathrm{~mL}1.00mL of 2.00102M2.00 \times 10^{-2} \mathrm{M}2.00102M NaCl\mathrm{NaCl}NaCl, the potential changed to 0.1846V-0.1846 \mathrm{~V}0.1846V. Calculate the Na+\mathrm{Na}^{+}Na+concentration of the original solution. Which of the following correctly compares the significance of the different technologies shown in the images? If you've accidentally put the card in the wrong box, just tap on the card to take it out of the box. For instance, one of the ways in which polyester is synthesized is by mixing the appropriate organic acid and alcohol in their liquid form. Which of the following is not required for osmosis to occur? In biological systems, diffusion occurs at every moment, across membranes in every cell as well as through the body. The image is a simple representation of the diffusion of one particle in another medium. 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. { "8.1:_Concentrations_of_Solutions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.
