Answer the following question given this paragraph: Visible light is the only light that humans can see. Different wavelengths of visible light appear as different colors. Radio waves have the longest wavelengths. They also have the least amount of energy. Infrared light has wavelengths too long for humans to see, but we can feel them as heat. The atmosphere absorbs the infrared light. Ultraviolet (UV) light is in wavelengths too short for humans to see. The most energetic UV light is harmful to life. The atmosphere absorbs most of this UV light from the Sun. Gamma rays have the highest energy and they are the most damaging rays. Fortunately, gamma rays don't penetrate Earth's atmosphere. Q: What is the only light that humans can see? Choices: - dark light - distinct light - bright light - visible light A:
visible light
Answer the following question given this paragraph: Ionic compounds consist of oppositely charged ions that are held together by ionic bonds. The opposite charges cancel out so ionic compounds have a net neutral charge. Ionic compounds form when metals transfer valence electrons to nonmetals. Q: What kind of charge do iconic compounds have? Choices: - net negative charge - net positive charge - white neutral charge - net neutral charge A:
net neutral charge
Q: Answer the following question given this paragraph: Q: What is a substance that increases the hydrogen ion concentration of a solution? Choices: - carbon - sulfur - base - acid A:
A: acid
Question: Answer the following question given this paragraph: In a syncline, rocks arch downward. A three-dimensional syncline is a basin. Q: What is a three dimensional snycline? Choices: - a crust - a gorge - a peak - a basin A:
Answer: a basin

Answer the following question given this paragraph: 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). Q: During which phase does dna replication occur in the cell cycle? Choices: - resting - gap - mitosis - synthesis A:
**Answer**
synthesis
Q: Answer the following question given this paragraph: Q: Nearly all apicomplexans are parasites of what? Choices: - stars - plants - fungi - animals A:
