Answer the following question given this paragraph: Bacteria and viruses can infect the brain or spinal cord. An infection of the brain is called encephalitis. An infection of the membranes that cover the brain and spinal cord is called meningitis. A vaccine is available to prevent meningitis caused by viruses (see Figure below ). Q: An infection of the brain is called? Choices: - tuberculosis - influenza - syphilis - encephalitis A:
encephalitis

Answer the following question given this paragraph: Darwin coined the term fitness to refer to an organism's relative ability to survive and produce fertile offspring. Nature selects the variations that are most useful. Therefore, he called this type of selection natural selection . Q: Who coined the term natural selection? Choices: - Pasteur - Mendel - shaw - darwin A:
(Answer)
darwin
Ques: Answer the following question given this paragraph: In a similar fashion, viral therapy uses viruses to genetically modify diseased cells and tissues. Viral therapy shows promise as a method of gene therapy and in the treatment of cancer. Gene therapy is the insertion of genes into a person's cells and tissues to treat a disease. In the case of a genetic disease, the defective gene is replaced with a working gene. Although the technology is still new, it has been used with some success. Q: Which therapy uses viruses to genetically modify diseased cells and tissues? Choices: - chemotherapy - digestive therapy - oxygen therapy - viral therapy A:
Ans: viral therapy

Answer the following question given this paragraph: CHAPTER REVIEW 24.1 Overview of Metabolic Reactions Metabolism is the sum of all catabolic (break down) and anabolic (synthesis) reactions in the body. The metabolic rate measures the amount of energy used to maintain life. An organism must ingest a sufficient amount of food to maintain its metabolic rate if the organism is to stay alive for very long. Catabolic reactions break down larger molecules, such as carbohydrates, lipids, and proteins from ingested food, into their constituent smaller parts. They also include the breakdown of ATP, which releases the energy needed for metabolic processes in all cells throughout the body. Anabolic reactions, or biosynthetic reactions, synthesize larger molecules from smaller constituent parts, using ATP as the energy source for these reactions. Anabolic reactions build bone, muscle mass, and new proteins, fats, and nucleic acids. Oxidation-reduction reactions transfer electrons across molecules by oxidizing one molecule and reducing another, and collecting the released energy to convert Pi and ADP into ATP. Errors in metabolism alter the processing of carbohydrates, lipids, proteins, and nucleic acids, and can result in a number of disease states. Q: Metabolism is the sum of all catabolic and which other reactions in the body? Choices: - inbolic - systic - abolic - anabolic A:
(A).
anabolic
Ques:Answer the following question given this paragraph: 5.3 Functions of the Integumentary System The skin plays important roles in protection, sensing stimuli, thermoregulation, and vitamin D synthesis. It is the first layer of defense to prevent dehydration, infection, and injury to the rest of the body. Sweat glands in the skin allow the skin surface to cool when the body gets overheated. Thermoregulation is also accomplished by the dilation or constriction of heat-carrying blood vessels in the skin. Immune cells present among the skin layers patrol the areas to keep them free of foreign materials. Fat stores in the hypodermis aid in both thermoregulation and protection. Finally, the skin plays a role in the synthesis of vitamin D, which is necessary for our well-being but not easily available in natural foods. Q: What system, which includes the skin, plays important roles in protection, sensing stimuli and thermoregulation? Choices: - digestive system - pectins system - teleporters system - integumentary system A:

Ans:integumentary system
Answer the following question given this paragraph: may be located in organs or tissues that have functions in addition to hormone production. Hormones circulate throughout the body and stimulate a response in cells that have receptors able to bind with them. The changes brought about in the receiving cells affect the functioning of the organ system to which they belong. Many of the hormones are secreted in response to signals from the nervous system, thus the two systems act in concert to effect changes in the body. Q: Many of the hormones are secreted in response to what signals of the body? Choices: - nose system signals - skeletal system signals - heart system signals - nervous system signals A:
nervous system signals
