Ques:Q: Ebola is an example of a disease spread by what kind of infectious agent? Read this paragraph and choose the correct option from the provided answers: Ebola is a rare and deadly disease caused by infection with a strain of Ebola virus. The 2014 Ebola epidemic is the largest in history, affecting multiple countries in West Africa, including Guinea, Sierra Leone and Liberia. Ebola is spread through direct contact with blood and body fluids of a person infected by and already showing symptoms of Ebola. Ebola is not spread through the air, water, food, or mosquitoes. See Ebola virus disease at http://www. who. int/mediacentre/factsheets/fs103/en/ for additional information. Choices: - bacteria - colds - flus - virus A:

Ans:virus

Ques:Q: What term describes a gene or sequence on a chromosome that co-segregates (shows genetic linkage) with a specific trait? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - nucleic acid chain - analogous effect - autosomal - genetic marker A:

Ans:genetic marker

Ques:Q: The temperature of the products is typically lower than the temperature of the reactants in what type of reaction? Read this paragraph and choose the correct option from the provided answers: In endothermic reactions, the temperature of the products is typically lower than the temperature of the reactants. The drop in temperature may be great enough to cause liquids to freeze. That's what happens in the endothermic reaction at this URL: http://www. bbc. co. uk/schools/gcsebitesize/science/add_aqa_pre_2011/chemreac/energychangesrev1. shtml . Choices: - autotrophic - exothermic - parabolic - endothermic A:

Ans:
endothermic
