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
Answer the following question given this paragraph: Metalloids are elements that have properties of both metals and nonmetals. Some can conduct electricity but only at certain temperatures. They may be shiny but brittle. All metalloids are solids at room temperature. Q: Elements that specifically are noted to have properties of both metals and nonmetals are known as what? Choices: - compund metals - alloys - alkali metals - metalloids A:
metalloids
Q: Answer the following question given this paragraph: Almost all plants make food by photosynthesis. Only about 1 percent of the estimated 300,000 species of plants have lost the ability to photosynthesize. These other species are consumers, many of them predators. How do plants prey on other organisms? The Venus fly trap in Figure below shows one way this occurs. Q: What is the process by which almost all plants make food? Choices: - reactions - digestion - melting - photosynthesis A:
A: photosynthesis
Question: Answer the following question given this paragraph: Earth is a giant magnet with north and south magnetic poles and a magnetic field called the magnetosphere. Evidence in rocks shows that Earth's magnetic poles switched positions hundreds of times in the past. Scientists think that Earth's magnetic field is caused by the movement of charged particles through molten metals in the outer core. Q: The magnet field of earth is called what? Choices: - atmosphere - troposphere - ionosphere - magnetosphere A:
Answer: magnetosphere

Answer the following question given this paragraph: Bird beaks are generally adapted for the food they eat. For example, the sharp, hooked beak of a raptor is well suited for killing and tearing apart prey. The long beak of the hummingbird in Figure below co-evolved with the tube-shaped flowers from which it sips nectar. Q: What part of a bird is adapted for the food it eats? Choices: - teeth - head - eye - beak A:
**Answer**
beak

Answer the following question given this paragraph: The population is an important unit in ecology as well as other biological sciences. How is a population defined, and what are the strengths and weaknesses of this definition? Are there some species that at certain times or places are not in populations?. Q: During interphase, the cell undergoes normal growth processes while also preparing for what, by accumulating energy and building blocks of dna? Choices: - proteins division - chromosome division - technology division - cell division A:
(Answer)
cell division
