Ques: Answer the following question given this paragraph: 22.4 Gas Exchange The behavior of gases can be explained by the principles of Dalton's law and Henry's law, both of which describe aspects of gas exchange. Dalton's law states that each specific gas in a mixture of gases exerts force (its partial pressure) independently of the other gases in the mixture. Henry's law states that the amount of a specific gas that dissolves in a liquid is a function of its partial pressure. The greater the partial pressure of a gas, the more of that gas will dissolve in a liquid, as the gas moves toward equilibrium. Gas molecules move down a pressure gradient; in other words, gas moves from a region of high pressure to a region of low pressure. The partial pressure of oxygen is high in the alveoli and low in the blood of the pulmonary capillaries. As a result, oxygen diffuses across the respiratory membrane from the alveoli into the blood. In contrast, the partial pressure of carbon dioxide is high in the pulmonary capillaries and low in the alveoli. Therefore, carbon dioxide diffuses across the respiratory membrane from the blood into the alveoli. The amount of oxygen and carbon dioxide that diffuses across the respiratory membrane is similar. Ventilation is the process that moves air into and out of the alveoli, and perfusion affects the flow of blood in the capillaries. Both are important in gas exchange, as ventilation must be sufficient to create a high partial pressure of oxygen in the alveoli. If ventilation is insufficient and the partial pressure of oxygen drops in the alveolar air, the capillary is constricted and blood flow is redirected to alveoli with sufficient ventilation. External respiration refers to gas exchange that occurs in the alveoli, whereas internal respiration refers to gas exchange that occurs in the tissue. Both are driven by partial pressure differences. Q: Dalton's law and henry's law both describe aspects of what type of exchange? Choices: - energy - electron - liquid - gas A:
Ans: gas

Answer the following question given this paragraph: Symbiosis is a close relationship between two species in which at least one species benefits. For the other species, the relationship may be positive, negative, or neutral. There are three basic types of symbiosis: mutualism, commensalism, and parasitism. Q: What is a close relationship between two species in which at least one species benefits called? Choices: - parasitic - morphogenesis - competition - symbiosis A:
(A).
symbiosis
Ques:Answer the following question given this paragraph: Even compounds with the same number of carbon and hydrogen atoms can have different shapes. These compounds are called isomers . Look at the examples in Figure below . The figure shows the structural formulas of butane and its isomer iso -butane. Both molecules have four carbon atoms and ten hydrogen atoms (C 4 H 10 ), but the atoms are arranged differently. Butane is a straight-chain molecule. Iso -butane is branched. You can see three-dimensional models of these two isomers at the URLs below. You can rotate the molecule models to get a better idea of their shapes. Q: What are compounds with the same number of carbon and hydrogen atoms called? Choices: - alcohols - hydrocarbons - monomers - isomers A:

Ans:isomers
