- Q1Certain species of whiptail lizards have only female individuals and no males. These lizards reproduce asexually. What is one disadvantage of asexual reproduction for these lizards?They are more likely to develop a variety of tail lengths.All the members of a population are genetically very similar and less able to survive environmental changes.They are smaller than lizards that reproduce sexually.A new population can be established by a single individual in a relatively short period of time.30sS7L3b
- Q2A group of students prepared a table listing the types of reproduction that occur in several organisms. Based on this information, which of the organisms can produce offspring that are genetically identical to the parent organism?Amoebas and yeasts onlyAmoebas, yeasts, hydras, and ferns onlyCats, hydras, frogs, and ferns onlyFerns only30sS7L3b
- Q3A tiger cub has a pattern of stripes on its fur that is similar to that of its parents. Where are the instructions stored that provide information for a tiger’s fur pattern?On the cell membraneOn genes within chromosomesIn the mitochondriaIn cytoplasm inside cells30sS7L3a
- Q4Three cousins have a similar appearance but different face shapes. Which of these cell components are most involved in determining the basic shape of each girl’s face?Chromosomes, chloroplasts, and vacuolesGenes, chromosomes, and nucleusVacuoles, nucleus, and chromosomesCytoplasm, chloroplasts, and genes30sS7L3a
- Q5In piranha, fish with large teeth represent the dominant trait. Because the dominant trait masks the recessive trait, we could expect about ________ of the next generation of fish to have SMALL teeth.50%25%75%0%30sS7L3b
- Q6In this Punnett square used to predict genetic crosses, RR represents the _________ of the organism.recessivephenotypegenotypeappearance30sS7L3b
- Q7Which of these is a homozygous dominant genotype?AAAaaaaaA30sS7L3b
- Q8Which statement MOST accurately describes the influences on a person’s length of life and quality of life?Both behaviors and genes influence the length and quality of lifeGenes alone determine both the length and quality of lifeBehaviors alone determine both the length and quality of lifeNeither genes nor behaviors influence the length or quality of life30sS7L3c
- Q9When Charles Darwin visited the Galápagos Islands in the 1800s, he observed many types of organisms that were similar but lived on different islands. The four species of mockingbirds found on the Galápagos Islands are shown below. Each species lives on a different island. These species are very similar, but the Hood mockingbird has a longer beak than the other three species. Which of the following best explains this difference?The Hood mockingbird needs a longer beak for defense against predators.The Hood mockingbird’s beak stretched to reach its food, and the longer beak was passed down to its offspring.The Hood mockingbird’s longer beak is an adaptation to the food available in the bird’s habitat.The Hood mockingbird originated from a different type of bird than the other species.30sS7L3c
- Q10How might farmers use selective breeding with their crops?Farmers use pesticides to kill insects that prey on their crops.Farmers remove weeds from their fields so they cannot reproduce.Plants that produce larger crops are crossed to produce the next generation.30sS7L3c
