Answer the following question given this paragraph: Mendeleev's table of the elements is called a periodic table because of its repeating pattern. Anything that keeps repeating is referred to as periodic. Other examples of things that are periodic include the monthly phases of the moon and the daily cycle of night and day. The term period refers to the interval between repetitions. For example, the moon's phases repeat every four weeks. In a periodic table of the elements, the periods are the rows of the table. In Mendeleev's table, each period contains eight elements, and then the pattern repeats in the next row. Q: Because of it's repeating pattern, what is mendeleev's table of the elements called? Choices: - serial chart - cycles table - phases table - periodic table A:
periodic table

Answer the following question given this paragraph: Telescopes that use lenses to bend light are called refracting telescopes , or refractors ( Figure below ). The earliest telescopes were all refractors. Many amateur astronomers still use refractors today. Refractors are good for viewing details within our solar system. Craters on the surface of Earth's Moon or the rings around Saturn are two such details. Q: What are telescopes that use lenses to bend light called? Choices: - reflecting telescopes - sliding telescopes - layering telescopes - refracting telescopes A:
refracting telescopes
