Q: Answer the following question given this paragraph: Respiratory Compensation Respiratory compensation for metabolic acidosis increases the respiratory rate to drive off CO2 and readjust the bicarbonate to carbonic acid ratio to the 20:1 level. This adjustment can occur within minutes. Respiratory compensation for metabolic alkalosis is not as adept as its compensation for acidosis. The normal response of the respiratory system to elevated pH is to increase the amount of CO2 in the blood by decreasing the respiratory rate to conserve CO2. There is a limit to the. Q: The normal response of the respiratory system to elevated ph is to increase the amount of what in the blood? Choices: - glucose - acid - red blood cells - co2 A:
A: co2

Q: Answer the following question given this paragraph: Scientists perform experiments to test their hypotheses because sometimes the nature of natural universe is not obvious. Q: Scientists perform experiments to test their hypotheses because sometimes the nature of natural universe is what? Choices: - become obvious - very obvious - this obvious - not obvious A:
A: not obvious

Q: Answer the following question given this paragraph: Deposition as a change of state often occurs in nature. For example, when warm moist air comes into contact with very cold surfacessuch as the ground or objects on the groundice crystals are deposited on them. These ice crystals are commonly called frost. Look at the dead leaf and blades of grass in the Figure below . They are covered with frost. If you look closely, you can see the individual crystals of ice. You can watch a demonstration of frost forming on the side of a very cold can at the URL below. (Click on the mulitmedia choice "Ice on a Can. "). The ice in the can has been cooled to a very low temperature by adding salt to it. If you want to do the demonstration yourself, follow the procedure at the URL. http://www. middleschoolchemistry. com/lessonplans/chapter2/lesson4. Q: What are the ice crystals that form on the ground called? Choices: - snow - granules - sleet - frost A:
A: frost

Q: Answer the following question given this paragraph: The boiling points of liquid also correlate to the strength of the intermolecular forces. Recall that diethyl ether has weak dispersion forces, which meant that the liquid has a high vapor pressure. The weak forces also mean that it does not require a large an input of energy to make diethyl ether boil and so it has a relatively low normal boiling point of 34.6C. Water, with its much stronger hydrogen bonding, has a low vapor pressure and a higher normal boiling point of 100C. Q: The boiling points of liquid also correlate to the strength of which forces? Choices: - centrifugal - supramolecular - gravitational - intermolecular A:
A: intermolecular
