See our Which of the following explains why multiple early hearths of domestication and diffusion of plants and animals arose across the world in Central America, the Fertile Crescent, the Indus River valley, and Southeast Asia? The Diffusion of Oxygen, Carbon Dioxide, and Inert Gas in Flowing Blood. Farmers in less developed countries were able to increase their profits from growing and exporting high-yield grain to levels similar to those in more developed countries. C. detoxify certain chemicals D. through oxidation reactions C. Extracellular fluid should be isotonic to intracellular fluid. Labor-intensive farming of vegetables is done in small-scale plots in market gardens, while extensive grain crops are grown in large-scale fields far from the market town. If for example there are alot of sodium ions outside, their positive charges will repel and like atoms don't like being near eachother so they flow to the other side if there's a way to. Which statement displays the address of the variable num1? The brands listed above are trademarks of 3M. Determine the type of membrane transport used to transport these sodium ions. In each cycle, three sodium ions exit the cell, while two potassium ions enter. Option C is the correct answer because Cultural divergence (CD) happens when two cultures separate, therefore CD explains the best concept of driving forces of contemporary cultural diffusion. The township-and-range survey system was based on a geometric grid pattern, while the long-lot system was a rectilinear pattern based upon waterways or roads. B. Molecules that cannot easily pass through the bilayer include ions and small hydrophilic molecules, such as glucose, and macromolecules, including proteins and RNA.
