  2. At a crime scene, detectives collected strands of hair and dusted surfaces to gather fingerprints. Forensic scientists compared the fingerprints using the computer database and analyzed the DNA in the hair. What characteristics of fingerprints and DNA help police solve the crime? Fingerprints and DNA can show the sex of the individual. Both DNA and fingerprints are unique to an individual. The state of fingerprints and DNA can show what time the crime occurred. Fingerprints and DNA tell whether the person is young or old.

  20. What is the main difference between cells in unicellular organisms and cells in in multi-cellular organisms? Cells in multi-cellular organisms are specialized to perform only certain tasks. Cells in unicellular organisms are organized into tissues and organs. Cells in unicellular organisms divide at a faster rate than cells in multi-cellular organisms. Cells in multi-cellular organisms contain only half of the genetic material as cells in unicellular organisms.

  22. Which of the following does not describe a function of the cell membrane? Cell membranes maintain homeostasis by controlling the movement of substances into and out of the cell. The cell membrane contains many different proteins that enable a cell to detect and respond to its surroundings. The cell membrane participates in both active and passive transport. The cell membrane aids in both mitosis and meiosis.

  26. Speckled (Bb) Dark Brown (BB) Light Brown (bb) The population of crabs living on a sandy beach exhibits three colors: dark brown, light brown, and speckled. The genotypes of these colors are BB for dark brown, bb for light brown, and Bb for speckled. The speckled color blends in extremely well with the color of the sand on the beach. The pattern appears to provide the speckled crabs with some protection from predatory birds. Based on your knowledge of natural selection and the information above, which of the following conclusions can be drawn? Only the speckled crabs will survive and all of the offspring will be speckled. The allele for light brown color will be lost because of predatory birds eating light brown crabs. The allele for dark brown color will be lost because of predatory birds eating dark brown crabs. Both allele for dark brown and the allele for light brown will continue to be passed on in the crab population.

  28. 1 2 3 4 Meiosis allows for genetic variation of offspring because parental alleles can be combined in different ways. A Punnett square shows how parental alleles can combine. The Punnett square below shows a cross between two rabbits. Black fur (B) is dominant to brown fur (b). What would be the phenotype of the offspring indicated by Box 3? Brown Mixture of brown and black Black The phenotype cannot be determined.

  32. Which statement explains why approximately half of an individual’s DNA sequence comes from each parent? A cell from one parent undergoes meiosis, producing offspring cells that have both parents’ DNA. A cell from one parent undergoes mitotic cell division, producing offspring cells that have only half of the parent’s DNA. Cells in the parents undergo meiosis, producing haploid gametes that meet up during fertilization to produce a diploid individual. Cells that parents undergo mitosis, producing offspring cells that meet up during fertilization to produce an individual with half of each parent’s DNA.

  42. Carl Linnaeus’s system of classification was based on his judgment of the importance of various similarities among living things. Scientists have traditionally used similarities in appearance and structure to group organisms. However, this approach has proven problematic. Identify one way that this approach could be problematic. Some groups look different and are not related. Some groups look similar but are not closely related. Some groups look different but are related. There is not consistent relationship between structures and relatedness.

  44. Jackrabbits live in warm environments in the southwestern United States. They have short hair and long ears that help them radiate heat. What would most likely happen to the jackrabbit population if the environment slowly began to cool? The jackrabbit population would migrate farther north. The jackrabbit population would definitely become extinct. The jackrabbit population would evolve to have longer, wider ears. The jackrabbit population would evolve to have thicker coat and hair.
