Answer:
water and land
Explanation:
I assume this is an open-ended question, so you could make an argument for lots of things, but these are the two most important ones in my opinion. The amount of freshwater on Earth is pretty small, only about 2.5%, and most of that is locked in ice. As the demand for food grows, the demand for water for crops and livestock also grows. This is in addition to the increase in water that is needed for a growing population. Climate change increases this problem because of drought. The second most important resource that will be affected is land. If we need more food, we also need space to grow crops and raise livestock. The available space is also reduced because people need places to live and we need to be able to grow trees for wood to build houses and other buildings. I argue that land and water will be the most in-demand commodities as the population continues to increase.
Carbon dioxide is generated in tissues as a byproduct of normal metabolism. It dissolves in blood plasma to form carbonic acid (H2CO3); red blood cell (RBC) carbonic anhydrase catalyzes this reaction. Carbonic acid then spontaneously dissociates to form bicarbonate (HCO3−) and a hydrogen ion (H+). In response to the decrease in intracellular <span>pCO2</span>, more CO2 passively diffuses into the cell.
Cell membranes are generally impermeable to charged ions (i.e. H+, HCO3− ) but RBCs are able to exchange bicarbonate for chloride using the anion exchanger protein Band 3. Thus, the rise in intracellular bicarbonate leads to bicarbonate export and chloride intake. The term "chloride shift" refers to this exchange. Consequently, chloride concentration is lower in systemic venous blood than in systemic arterial blood: high venous pCO2 leads to bicarbonate production in RBCs, which then leaves the RBC in exchange for chloride coming in.<span>[2]</span>
Answer:
To calculate the molarity of a solution, you divide the moles of solute by the volume of the solution expressed in liters.
Explanation:
The molarity (M) of a solution is the number of moles of solute dissolved in one liter of solution. To calculate the molarity of a solution, you divide the moles of solute by the volume of the solution expressed in liters.
The correct answer is by composition and texture. Composition is that minerals that the rock are made of. Texture refers to the grain size of the different components of that rock. Texture has to do with sizes of mineral grains and other constituents in a rock and how the sizes and shapes relate to each other.
Answer:
Explanation: The possible genotypes from this cross are Rr, rr, Rr, and rr. So, that means two offspring will be red and two will be white. The percentage chance for each phenotype is: 50% chance for red flowers and 50% chance for white flowers.
