Answer the following question given this paragraph: Amines are molecules that contain carbon-nitrogen bonds. The nitrogen atom in an amine has a lone pair of electrons and three bonds to other atoms, either carbon or hydrogen. Various nomenclatures are used to derive names for amines, but all involve the class-identifying suffix ine as illustrated here for a few simple examples:. Q: What term is used to describe molecules that contain carbon-nitrogen bonds? Choices: - compounds - ions - nitrites - amines A:
amines
Q: Answer the following question given this paragraph: The girl pictured above became negatively charged because electrons flowed from the van de Graaff generator to her. Whenever electrons are transferred between objects, neutral matter becomes charged. This occurs even with individual atoms. Atoms are neutral in electric charge because they have the same number of negative electrons as positive protons. However, if atoms lose or gain electrons, they become charged particles called ions. You can see how this happens in the Figure below . When an atom loses electrons, it becomes a positively charged ion, or cation. When an atom gains electrons, it becomes a negative charged ion, or anion. Q: Gain or loss of what causes an atom to become a negatively or positively charged ion? Choices: - protons - neutrons - nucleus - electrons A:
A: electrons
Question: Answer the following question given this paragraph: Metals tend to be malleable. This means that they can be formed into thin sheets without breaking. An example is aluminum foil, also pictured in the Figure below . Q: What is an element that tend to be malleable? Choices: - actinide - mixture - lanthanide - metal A:
Answer: metal

Answer the following question given this paragraph: 9.2 Fibrous Joints Fibrous joints are where adjacent bones are strongly united by fibrous connective tissue. The gap filled by connective tissue may be narrow or wide. The three types of fibrous joints are sutures, gomphoses, and syndesmoses. A suture is the narrow fibrous joint that unites most bones of the skull. At a gomphosis, the root of a tooth is anchored across a narrow gap by periodontal ligaments to the walls of its socket in the bony jaw. A syndesmosis is the type of fibrous joint found between parallel bones. The gap between the bones may be wide and filled with a fibrous interosseous membrane, or it may narrow with ligaments spanning between the bones. Syndesmoses are found between the bones of the forearm (radius and ulna) and the leg (tibia and fibula). Fibrous joints strongly unite adjacent bones and thus serve to provide protection for internal organs, strength to body regions, or weight-bearing stability. Q: Sutures, gomphoses, and syndesmoses are types of what, which are found where adjacent bones are strongly united by connective tissue? Choices: - cartilage - metallic joints - ligaments - fibrous joints A:
**Answer**
fibrous joints

Choices: - opaque, invisible, visible - transitive, opaque, translucent - extensive , opaque , translucent - transparent, opaque, translucent A:
(Answer)
transparent, opaque, translucent
