Answer the following question given this paragraph: Reflecting surfaces do not have to be flat. The most common curved mirrors are spherical. A spherical mirror is called a concave mirror if the center of the mirror is further from the viewer than the edges are. A spherical mirror is called a convex mirror if the center of the mirror is closer to the viewer than the edges are. Q: The most common curved mirrors are what? Choices: - solid - concave - convex - spherical A:
spherical
Answer the following question given this paragraph: 6.1 | The Genome By the end of this section, you will be able to: Describe the prokaryotic and eukaryotic genome Distinguish between chromosomes, genes, and traits The continuity of life from one cell to another has its foundation in the reproduction of cells by way of the cell cycle. The cell cycle is an orderly sequence of events in the life of a cell from the division of a single parent cell to produce two new daughter cells, to the subsequent division of those daughter cells. The mechanisms involved in the cell cycle are highly conserved across eukaryotes. Organisms as diverse as protists, plants, and animals employ similar steps. Q: What do we call the orderly sequence of events in the life of a cell from the division of a single parent cell to produce two new daughter cells, to the subsequent division of those daughter cells? Choices: - cell death - cell replication - circadian cycle - cell cycle A:
cell cycle
Q: Answer the following question given this paragraph: Some species of animals are territorial . This means that they defend their area. The area they defend usually contains their nest and enough food for themselves and their offspring. A species is more likely to be territorial if there is not very much food in their area. Animals generally do not defend their territory by fighting. Instead, they are more likely to use display behavior. The behavior tells other animals to stay away. It gets the message across without the need for fighting. Display behavior is generally safer and uses less energy than fighting. Male gorillas use display behavior to defend their territory. They pound on their chests and thump the ground with their hands to warn other male gorillas to keep away from their area. The robin displays his red breast to warn other robins to stay away ( Figure below ). Q: Animals that defend their area are generally known as what kinds of animals? Choices: - mutants - neutral - carnivores - territorial A:
A: territorial
Question: Answer the following question given this paragraph: Ionic compounds take on the form of extended three-dimensional arrays of cations and anions. Q: Ionic compounds take on the form of extended three-dimensional arrays of cations and what else? Choices: - oxides - electrons - crystals - anions A:
Answer: anions

Answer the following question given this paragraph: You can see how Mendeleev organized the elements in Figure below . From left to right across each row, elements are arranged by increasing atomic mass. Mendeleev discovered that if he placed eight elements in each row and then continued on to the next row, the columns of the table would contain elements with similar properties. He called the columns groups . They are sometimes called families, because elements within a group are similar but not identical to one another, like people in a family. Q: In the periodic table, elements are arranged from left to right according to what property? Choices: - metallic mass - real mass - major mass - atomic mass A:
**Answer**
atomic mass
Answer the following question given this paragraph: 17.2 | Mapping Genomes By the end of this section, you will be able to: Define genomics Describe genetic and physical maps Describe genomic mapping methods Genomics is the study of entire genomes, including the complete set of genes, their nucleotide sequence and organization, and their interactions within a species and with other species. Genome mapping is the process of finding the locations of genes on each chromosome. The maps created by genome mapping are comparable to the maps that we use to navigate streets. A genetic map is an illustration that lists genes and their location on a chromosome. Genetic maps provide the big picture (similar to a map of interstate highways) and use genetic markers (similar to landmarks). A genetic marker is a gene or sequence on a chromosome that co-segregates (shows genetic linkage) with a specific trait. Early geneticists called this linkage analysis. Physical maps present the intimate details of smaller regions of the chromosomes (similar to a detailed road map). A physical map is a representation of the physical distance, in nucleotides, between genes or genetic markers. Both genetic linkage maps and physical maps are required to build a complete picture of the genome. Having a complete map of the genome makes it easier for researchers to study individual genes. Human genome maps help researchers in their efforts to identify human disease-causing genes related to illnesses like cancer, heart disease, and cystic fibrosis. Genome mapping can be used in a variety of other applications, such as using live microbes to clean up pollutants or even prevent pollution. Research involving plant genome mapping may lead to producing higher crop yields or developing plants that better adapt to climate change. Q: What term describes a gene or sequence on a chromosome that co-segregates (shows genetic linkage) with a specific trait? Choices: - nucleic acid chain - analogous effect - autosomal - genetic marker A:
genetic marker
