user: Answer the following question given this paragraph:   Eukaryotic cells contain a nucleus and several other types of organelles. These structures are involved in many vital cell functions.   Q: What type of cell contains a nucleus?   Choices:  - candid cell  - endogenous cell  - chloroplasts cell  - eukaryotic cell  A:
eukaryotic cell


Answer the following question given this paragraph:   automobile axle drives a wheel, which has a much larger diameter than the axle. The MA is less than 1. (c) An ordinary pulley is used to lift a heavy load. The pulley changes the direction of the force T exerted by the cord without changing its magnitude. Hence, this machine has an MA of 1.   Q: A pulley changes the direction of the force t exerted by the cord without changing its what?   Choices:  - longitude  - latitude  - position  - magnitude  A:
magnitude


Q: Answer the following question given this paragraph:   Appendix: Periodic Table of the Elements In this chapter, we present some data on the chemical elements. The periodic table, introduced in Chapter 3 "Atoms, Molecules, and Ions", lists all the known chemical elements, arranged by atomic number (that is, the number of protons in the nucleus). The periodic table is arguably the best tool in all of science; no other branch of science can summarize its fundamental constituents in such a concise and useful way. Many of the physical and chemical properties of the elements are either known or understood based on their positions on the periodic table. Periodic tables are available with a variety of chemical and physical properties listed in each element’s box. What follows here is a more complex version of the periodic table than what was presented inChapter 3 "Atoms, Molecules, and Ions". The Internet is a great place to find periodic tables that contain additional information. One item on most periodic tables is the atomic mass of each element. For many applications, only one or two decimal places are necessary for the atomic mass. However, some applications (especially nuclear chemistry; see Chapter 15 "Nuclear Chemistry") require more decimal places. The atomic masses in Table 17.1 "The Basics of the Elements of the Periodic Table" represent the number of decimal places recognized by the International Union of Pure and Applied Chemistry, the worldwide body that develops standards for chemistry. The atomic masses of some elements are known very precisely, to a large number of decimal places. The atomic masses of other elements, especially radioactive elements, are not known as precisely. Some elements, such as lithium, can have varying atomic masses depending on how their isotopes are isolated. The web offers many interactive periodic table resources. For example, seehttp://www. ptable.   Q: What organizational tool, arguably the best in all of science, lists all the known chemical elements, arranged by atomic number?   Choices:  - tide table  - logic table  - spreadsheet  - periodic table  A:
A: periodic table


Question: Answer the following question given this paragraph:   Covalent bonds form because they give atoms a more stable arrangement of electrons. Look at the oxygen atoms in the Figure above . Alone, each oxygen atom has six valence electrons. By sharing two pairs of valence electrons, each oxygen atom has a total of eight valence electrons. This fills its outer energy level, giving it the most stable arrangement of electrons. The shared electrons are attracted to both oxygen nuclei, and this force of attraction holds the two atoms together in the oxygen molecule.   Q: What do covalent bonds give atoms a more stable arrangement of?   Choices:  - protons  - neutrons  - cell walls  - electrons  A:
Answer: electrons


*Question*
Answer the following question given this paragraph:   The modern periodic table is based on atomic number. Elements in each period go from metals on the left to metalloids and then nonmetals on the right. Within groups, elements have similar properties.   Q: What is the modern periodic table based on?   Choices:  - element mass  - metallic number  - element density  - atomic number  A:
**Answer**
atomic number


Q: Answer the following question given this paragraph:   Lysosomes are like the recycling trucks that carry waste away from the factory. Lysosomes have digestive enzymes that break down old molecules into parts that can be recycled.   Q: Lysosomes have what type of enzymes that break down old molecules into parts that can be recycled?   Choices:  - corrosive  - bacterial  - probiotics  - digestive  A:


assistant: A: digestive
