Answer the following question given this paragraph: The range is the total spread of values. It gives you an idea of the variation in the measurements. The range is calculated by subtracting the smallest value from the largest value. For the data in Table above , the range in numbers of vehicles by type is: 150 - 50 = 100. Q: What is calculated by subtracting the smallest value from the largest value? Choices: - the sample - the density - the median - the range A:
the range

Answer the following question given this paragraph: This diagram represents the cell cycle in eukaryotes. The cell cycle depicts the life of an eukaryotic cell. The cell cycle has four phases: the first growth or gap (G 1 ) phase, the synthesis (S) phase, the second growth or gap (G 2 ) phase and the mitotic (M) phase. The M phase includes mitosis and cytokinesis. The cell spends the majority of the cycle in the first three phases (G 1 , S, G 2 ) of the cycle, collectively known as interphase. After cytokinesis, two genetically identical daughter cells are formed. Q: How many cycles do cells have? Choices: - six - two - seven - four A:
four

Q: All living things maintain a stable internal environment through what process? Choices: - consciousness - alertness - maintenance - homeostasis A:

Answer the following question given this paragraph: Mutations , changes in the DNA or RNA sequence, can have significant phenotypic effects or they can have no effects. What are possible outcomes of some of those mutations. Some can produce genetic disorder . A genetic disorder is a condition caused by abnormalities, such as mutations, in your genes or chromosomes. Genetic disorders are usually present from conception. These disorders include chromosomal abnormalities, in which the individual has too few or too many chromosomes or chromosomes with large alterations, or diseases due to a mutation in a specific gene. These defective genes are usually inherited from the parents, hence the term hereditary disease or genetic disorder. Genetic disorders can be inherited in a dominant or recessive manner ( Figure below and Figure below ). Recessive disorders require the inheritance of a defective gene from each parent. The parents are usually unaffected and are healthy carriers of the defective gene. Q: What is the medical term for a condition caused by abnormalities, such as mutations, in your genes or chromosomes? Choices: - mutations disorder - nervous disorder - radiation disorder - genetic disorder A:
genetic disorder
