Answer the following question given this paragraph: Temperature falls from the equator to the poles. Therefore, major temperature zones are based on latitude . They include tropical, temperate, and arctic zones (see Figure below ). However, other factors besides latitude may also influence temperature. For example, land near the ocean may have cooler summers and warmer winters than land farther inland. This is because water gains and loses heat more slowly than does land, and the water temperature influences the temperature on the coast. Temperature also falls from lower to higher altitudes. That's why tropical zone mountain tops may be capped with snow. Q: What are major temperature zones primarily based on? Choices: - altitude - longitude - gps - latitute A:
(Answer)
latitute

Answer the following question given this paragraph: Proteins Function as Enzymes If you were trying to type a paper, and every time you hit a key on your laptop there was a delay of six or seven minutes before you got a response, you would probably get a new laptop. In a similar way, without enzymes to catalyze chemical reactions, the human body would be nonfunctional. It functions only because enzymes function. Enzymatic reactionschemical reactions catalyzed by enzymesbegin when substrates bind to the enzyme. A substrate is a reactant in an enzymatic reaction. This occurs on regions of the enzyme known as active sites (Figure 2.27). Any given enzyme catalyzes just one type of chemical reaction. This characteristic, called specificity, is due to the fact that a substrate with a particular shape and electrical charge can bind only to an active site corresponding to that substrate. Q: What is the name of a reactant in an enzymatic reaction? Choices: - membrane - Scar - tissues - substrate A:
(A).
substrate
Ques:Answer the following question given this paragraph: Much less solar energy gets to the poles. Q: What parts of the planet does solar energy have difficulty reaching? Choices: - oceans - deserts - equators - poles A:

Ans:poles
Answer the following question given this paragraph: Figure 2.13 Oil and water do not mix. As this macro image of oil and water shows, oil does not dissolve in water but forms droplets instead. This is due to it being a nonpolar compound. (credit: Gautam Dogra). Q: What does oil do when mixed with water? Choices: - dissolves - precipitates - dissappears - forms droplets A:
forms droplets
