Answer the following question given this paragraph: Sedimentary rocks form from sediments that are cemented and compacted. Q: What type of rocks form from sediments that are cemented and compacted? Choices: - limestone - granite - crystalline - sedimentary A:
sedimentary
Answer the following question given this paragraph: When a warm air mass runs into a cold air mass, it creates a warm front ( Figure below ). The warm air mass is moving faster than the cold air mass. The warm air mass then flows up over the cold air mass. As the warm air rises, it cools. This brings about clouds and sometimes light precipitation. Warm fronts move slowly and cover a wide area. After a warm front passes, the warm air mass behind it brings warmer temperatures. The warm air is also likely to be more humid. Q: What results when a warm air mass runs into a cold air mass? Choices: - cool front - dry front - rough front - warm front A:
warm front
Q: Answer the following question given this paragraph: Felsic lavas are more viscous and erupt explosively or do not erupt. Mafic lavas are less viscous and erupt effusively. Q: Which type of lava lavas are less viscous and erupt effusively? Choices: - Ultramafic lava - Intermediate lava - Felsic lava - mafic A:
A: mafic
Question: Answer the following question given this paragraph: Chromosomal alterations are mutations that change chromosome structure. They occur when a section of a chromosome breaks off and rejoins incorrectly or does not rejoin at all. Possible ways these mutations can occur are illustrated in Figure below . Go to this link for a video about chromosomal alterations: http://www. youtube. com/watch?v=OrXRSqa_3lU (2:18). Q: Chromosomal alterations are mutations that change what? Choices: - Skeleton Structure - detected structure - discovery structure - chromosome structure A:
Answer: chromosome structure

Answer the following question given this paragraph: Microscopes were first developed in the early 1600s by eyeglass makers in The Netherlands and Denmark. The simplest compound microscope is constructed from two convex lenses as shown schematically in Figure 26.16. The first lens is called the objective lens, and has typical magnification values from 5 to 100 . In standard microscopes, the objectives are mounted such that when you switch between objectives, the sample remains in focus. Objectives arranged in this way are described as parfocal. The second, the eyepiece, also referred to as the ocular, has several lenses which slide inside a cylindrical barrel. The focusing ability is provided by the movement of both the objective lens and the eyepiece. The purpose of a microscope is to magnify small objects, and both lenses contribute to the final magnification. Additionally, the final enlarged image is produced in a location far enough from the observer to be easily viewed, since the eye cannot focus on objects or images that are too close. Q: Microscopes were first developed in the early 1600s by this trade? Choices: - food makers - polyurethane makers - watch makers - eyeglass makers A:
**Answer**
eyeglass makers
Answer the following question given this paragraph: Some of the most important animal behaviors involve mating. Mating is the pairing of an adult male and female to produce young. Adults that are most successful at attracting a mate are most likely to have offspring. Traits that help animals attract a mate and have offspring increase their fitness. As the genes that encode these traits are passed to the next generation, the traits will become more common in the population. Q: What is the pairing of an adult male to an adult female to produce young? Choices: - evolution - asexual reproduction - binary fission - mating A:
mating
