Answer the following question given this paragraph: to within the alveoli. As a result, carbon dioxide dissociates readily from hemoglobin and diffuses across the respiratory membrane into the air. In addition to the partial pressure of carbon dioxide, the oxygen saturation of hemoglobin and the partial pressure of oxygen in the blood also influence the affinity of hemoglobin for carbon dioxide. The Haldane effect is a phenomenon that arises from the relationship between the partial pressure of oxygen and the affinity of hemoglobin for carbon dioxide. Hemoglobin that is saturated with oxygen does not readily bind carbon dioxide. However, when oxygen is not bound to heme and the partial pressure of oxygen is low, hemoglobin readily binds to carbon dioxide. Q: When oxygen is not bound to heme and the partial pressure of oxygen is low, hemoglobin readily binds to what? Choices: - iron - carbon - sulfur - carbon dioxide A:
carbon dioxide
Answer the following question given this paragraph: The molecular mass is the sum of the masses of the atoms in the formula. Q: The sum of the masses of the atoms in the formula is referred to as what? Choices: - nucleus mass - magnetic mass - atomic mass - molecular mass A:
molecular mass
Q: Answer the following question given this paragraph: electrolysis2NaOH ( aq )+Cl2 ( g )+H 2 ( g ) Bromine is much less abundant than fluorine or chlorine, but it is easily recovered from seawater, which contains about 65 mg of Br per liter. Salt lakes and underground brines are even richer sources; for example, the Dead Sea contains 4 g of Br per liter. Iodine is the least abundant of the nonradioactive halogens, and it is a relatively rare element. Because of its low electronegativity, iodine tends to occur in nature in an oxidized form. Hence most commercially important deposits of iodine, such as those in the Chilean desert, are iodate salts such as Ca(IO3)2. The production of iodine from such deposits therefore requires reduction rather than oxidation. The process is typically carried out in two steps: reduction of iodate to iodide with sodium hydrogen sulfite, followed by reaction of iodide with additional iodate: Equation 22.41. Q: Bromine is much less abundant than fluorine or chlorine, but it is easily recovered from seawater, which contains about 65 mg of br per what? Choices: - pound - foot - gallon - liter A:
A: liter
Question: Answer the following question given this paragraph: The parasympathetic division controls internal organs and glands during the rest of the time. It controls processes like digestion, heartbeat, and breathing when there is not an emergency. Q: Which division of the autonomic nervous system controls processes like digestion, heartbeat, and breathing? Choices: - endocrine - synaptic - dopaminergic - parasympathetic A:
Answer: parasympathetic

Answer the following question given this paragraph: Many people get their freshwater from an aquifer. They obtain the water through a well. A well is a hole that is dug or drilled through the ground down to an aquifer. Q: What is hole that is dug or drilled through the ground down to an aquifer? Choices: - big hole - elevator - cave - well A:
**Answer**
well

Answer the following question given this paragraph: Photosynthesis begins with the light reactions. It is during these reactions that the energy from sunlight is absorbed by the pigment chlorophyll in the thylakoid membranes of the chloroplast. The energy is then temporarily transferred to two molecules, ATP and NADPH, which are used in the second stage of photosynthesis. ATP and NADPH are generated by two electron transport chains . During the light reactions, water is used and oxygen is produced. These reactions can only occur during daylight as the process needs sunlight to begin. Q: What is produced during the light reactions in photosynthesis? Choices: - carbon - waste - nitrogen - oxygen A:
(Answer)
oxygen
