Question: Q: During which phase does dna replication occur in the cell cycle? Read this paragraph and choose the correct option from the provided answers: 9.2 | DNA Replication By the end of this section, you will be able to: Explain the process of DNA replication Explain the importance of telomerase to DNA replication Describe mechanisms of DNA repair When a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis. The elucidation of the structure of the double helix provided a hint as to how DNA is copied. Recall that adenine nucleotides pair with thymine nucleotides, and cytosine with guanine. This means that the two strands are complementary to each other. For example, a strand of DNA with a nucleotide sequence of AGTCATGA will have a complementary strand with the sequence TCAGTACT (Figure 9.8). Choices: - resting - gap - mitosis - synthesis A:
Answer: synthesis

Question: Q: What helps treat bacterial infections in people? Read this paragraph and choose the correct option from the provided answers: Bacteria in food or water usually can be killed by heating it to a high temperature. Generally, this temperature is at least 71 C (160 F). Bacteria on surfaces such as countertops and floors can be killed with disinfectants, such as chlorine bleach. Bacterial infections in people can be treated with antibiotic drugs . These drugs kill bacteria and may quickly cure the disease. If you've ever had strep throat, you were probably prescribed an antibiotic to treat it. Choices: - respiratory drugs - vaccines - rest - antibiotic drugs A:
Answer: antibiotic drugs

Question: Q: Rising air currents carry water vapor into what? Read this paragraph and choose the correct option from the provided answers: Rising air currents carry water vapor into the atmosphere. As the water vapor rises in the atmosphere, it cools and condenses. Condensation is the process in which water vapor changes to tiny droplets of liquid water. The water droplets may form clouds. If the droplets get big enough, they fall as precipitation rain, snow, sleet, hail, or freezing rain. Most precipitation falls into the ocean. Eventually, this water evaporates again and repeats the water cycle. Some frozen precipitation becomes part of ice caps and glaciers. These masses of ice can store frozen water for hundreds of years or longer. Choices: - stratosphere - ionosphere - troposphere - atmosphere A:
Answer:
atmosphere
