Answer the following question given this paragraph: Note Organic and biochemical equations are frequently written showing only the organic reactants and products. In this way, we focus attention on the organic starting material and product, rather than on balancing complicated equations. Ethanol is oxidized in the liver to acetaldehyde:. Q: Organic and biochemical equations show the initial and final products of the equation, respectively known as the reactants and what else? Choices: - consumers - dividends - reactors - products A:
products

(Answer)
stronger

Answer the following question given this paragraph: Salty taste is simply the perception of sodium ions (Na+) in the saliva. When you eat something salty, the salt crystals dissociate into the component ions Na+ and Cl, which dissolve into the saliva in your mouth. The Na+ concentration becomes high outside the gustatory cells, creating a strong concentration gradient that drives the diffusion of the ion into the cells. The entry of Na+ into these cells results in the depolarization of the cell membrane and the generation of a receptor potential. Sour taste is the perception of H+ concentration. Just as with sodium ions in salty flavors, these hydrogen ions enter the cell and trigger depolarization. Sour flavors are, essentially, the perception of acids in our food. Increasing hydrogen ion concentrations in the saliva (lowering saliva pH) triggers progressively stronger graded potentials in the gustatory cells. For example, orange juicewhich contains citric acidwill taste sour because it has a pH value of approximately 3. Of course, it is often sweetened so that the sour taste is masked. The first two tastes (salty and sour) are triggered by the cations Na+ and H+. The other tastes result from food molecules binding to a G proteincoupled receptor. A G protein signal transduction system ultimately leads to depolarization of the gustatory cell. The sweet taste is the sensitivity of gustatory cells to the presence of glucose dissolved in the saliva. Other monosaccharides such as fructose, or artificial sweeteners such as aspartame (NutraSweet™️), saccharine, or sucralose (Splenda™️) also activate the sweet receptors. The affinity for each of these molecules varies, and some will taste sweeter than glucose because they bind to the G proteincoupled receptor differently. Bitter taste is similar to sweet in that food molecules bind to G proteincoupled receptors. However, there are a number of different ways in which this can happen because there are a large diversity of bitter-tasting molecules. Some bitter molecules depolarize gustatory cells, whereas others... Q: Just as salty taste involves perception of sodium ions in saliva, what taste correlates with presence of glucose? Choices: - salty - bitter - sour - sweet A:
(A).
sweet
Ques:Answer the following question given this paragraph: Wind energy is energy provided by the blowing wind. Wind turbines, like those in Figure above , can turn wind energy into electricity. The wind blows because of differences in heating of Earth's atmosphere by the sun. There will never be a shortage of wind. Q: What do wind turbines turn wind energy into? Choices: - hydrogen - carbon - oxygen - electricy A:

Ans:electricy

Choices: - momentum - kinetic energy - electromagnetism - electrical potential A:

Ans:
electrical potential
