Answer the following question given this paragraph: Water shortages are common in much of the world. People are most likely to run short of water during droughts. A drought is a period of unusually low rainfall. Human actions have increased how often droughts occur. One way people can help to bring on drought is by cutting down trees. Trees add a lot of water vapor to the air. With fewer trees, the air is drier and droughts are more common. Q: Because trees add water vapor to air, cutting down forests leads to longer periods of what? Choices: - ice - harvest - flooding - drought A:
(Answer)
drought
Ques: Answer the following question given this paragraph: culture (outside the body under optimal growing conditions), the length of the cycle is about 24 hours. In rapidly dividing human cells with a 24-hour cell cycle, the G1 phase lasts approximately nine hours, the S phase lasts 10 hours, the G2 phase lasts about four and one-half hours, and the M phase lasts approximately one-half hour. In early embryos of fruit flies, the cell cycle is completed in about eight minutes. The timing of events in the cell cycle is controlled by mechanisms that are both internal and external to the cell. Q: The timing of events in what cycle - which lasts just minutes in fruit fly embryos - is controlled by mechanisms that are both internal and external to the cell? Choices: - circadian cycle - carbon cycle - life cycle - cell cycle A:
Ans: cell cycle

Answer the following question given this paragraph: Individual nucleotides can be linked together through their phosphate groups to form nucleic acid polymers. Once constructed, DNA generally exists as two strands that are linked together by hydrogen bonds, producing a double-helical structure (see Figure below ). Q: Individual nucleotides can be linked together through their phosphate groups to form? Choices: - atoms - nitrous acid polymers - dna - nucleic acid polymers A:
nucleic acid polymers
