Answer the following question given this paragraph: Carbonate minerals are often found where seas once covered the land. Some carbonate minerals are very common. Calcite contains calcium, carbon, and oxygen. Have you ever been in a limestone cave or seen a marble tile? Calcite is in both limestone and marble. Azurite and malachite are also carbonate minerals. They contain copper instead of calcium. They are not as common as calcite. Malachite and azurite are used in jewelry; as you can see, they are very colorful ( Figure below ). Q: What type of minerals are often found where seas once covered the land? Choices: - magnesium - crystals - sea salt - carbonate A:
carbonate
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:
synthesis
Q: Answer the following question given this paragraph: Coefficients are used to balance chemical equations. A coefficient is a number placed in front of a chemical symbol or formula. It shows how many atoms or molecules of the substance are involved in the reaction. Q: What is the number placed in front of a chemical symbol or formula that shows how many atoms or molecules of the substance are involved in the reaction? Choices: - requirement - frequency - note - coefficient A:
A: coefficient
Question: Answer the following question given this paragraph: The period to which a given element belongs can easily be determined from its electron configuration. For example, consider the element nickel (Ni). Its electron configuration is [Ar]3 d 8 4 s 2 . The highest occupied principal energy level is the fourth, indicated by the 4 in the 4 s 2 portion of the configuration. Therefore, nickel can be found in the fourth period of the periodic table. Q: In which period of the periodic table is nickel found? Choices: - First Period - Second Period - Third Period - fourth period A:
Answer: fourth period

Answer the following question given this paragraph: Eris is the largest known dwarf planet in the solar system. It is 27 percent larger than Pluto ( Figure above ). Like Pluto and Makemake, Eris is in the Kuiper belt. But Eris is about three times farther from the Sun than Pluto. Because of its distance, Eris was not discovered until 2005. Early on, it was thought that Eris might be the tenth planet. Its discovery helped astronomers realize that they needed a new definition of "planet. " Eris has a small moon that orbits Eris once about every 16 days. Q: What large dwarf planet in our solar system was only discovered in 2005? Choices: - artemis - Cerus - zeus - eris A:
**Answer**
eris
