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:
(Answer)
co2
Ques: Answer the following question given this paragraph: Life on Earth is carbon-based. Organisms need not only energy but also carbon atoms for building bodies. For nearly all life, the ultimate source of carbon is carbon dioxide (CO 2 ), an inorganic molecule. CO 2 makes up less than 1% of the Earth's atmosphere. Q: Life on earth is carbon-based. organisms need not only energy but also carbon ________ for building bodies? Choices: - monoxide - ions - crystals - atoms A:
Ans: atoms
(Q).
Answer the following question given this paragraph: Unlike oxygen, carbon dioxide is more concentrated in the blood in the capillaries surrounding the alveoli than it is in the air inside the alveoli. Therefore, carbon dioxide diffuses in the opposite direction. It moves out of the blood and into the air. Q: Which gas moves from the blood in the capillaries into the air? Choices: - nitrogen - carbon monoxide - oxygen - carbon dioxide A:
(A).
carbon dioxide
Ques:Answer the following question given this paragraph: Gap genes themselves are under the effect of maternal effect genes, such as bicoid and nanos. Gap genes also regulate each other to achieve their precise striped expression patterns. The maternal effect is when the phenotype of offspring is partly determined by the phenotype of its mother, irrespective of genotype. This often occurs when the mother supplies mRNA or proteins to the egg, affecting early development. In developing Drosophila, maternal effects include axis determination. Q: What is the term for when the phenotype of offspring is partly determined by the phenotype of its mother, irrespective of genotype? Choices: - congenital effect - uterine effect - oceanic effect - maternal effect A:

Ans:maternal effect
Question: Answer the following question given this paragraph: 34.6 High-temperature Superconductors Superconductors are materials with a resistivity of zero. They are familiar to the general public because of their practical applications and have been mentioned at a number of points in the text. Because the resistance of a piece of superconductor is zero, there are no heat losses for currents through them; they are used in magnets needing high currents, such as in MRI machines, and could cut energy losses in power transmission. But most superconductors must be cooled to temperatures only a few kelvin above absolute zero, a costly procedure limiting their practical applications. In the past decade, tremendous advances have been made in producing materials that become superconductors at relatively high temperatures. There is hope that room temperature superconductors may someday be manufactured. Q: Superconductors are materials with a resistivity of? Choices: - above zero - greater density - high magnitude - zero A:
Answer:
zero
