- 1. Multiple Choice
The picture above shows a protist undergoing cell division.As the parent cell divides, it will —form offspring that learn to look like the parent through factors in the environment.teach its offspring to look and act like it.pass on genetic information to its offspring through heredity.hold onto some genetic material so that its offspring only get some of its traits. - 2. Multiple ChoiceWhich of the following defines heredity?The passage of genetic instructions from one generation to the nextThe manipulated changing of a trait in an organismhe ability of organisms to adapt to their environmentThe study of how characteristics are passed on from parent to offspring
- 3. Multiple ChoiceThe populations of certain countries contain more blond people than the populations of other countries. This trend is explained through heredity, because —blond people in these countries are reproducing with other blond people, passing down genes that have instructions for blond hair color.hair color is part of a country's culture, so many of the people born in a country all have the same hair color.blond people carry a gene that causes their offspring to have blond hair even if the other parent has dark hair.over time, the climate of an area determines how the appearance of people living in the area will look.
- 4. Multiple ChoiceWhich of the following best explains the difference between the terms “genetics” and “heredity”?Genetics is the study of recessive traits; heredity is the study of dominant traits.Genetics is the study of dominant traits; heredity is the study of recessive traits.Genetics is the study of genes; heredity is the study of how genes are transferred from one generation to the next.Genetics is the study of how genes are transferred from one generation to the next, heredity is the study of genes.
- 5. Multiple ChoiceDuring asexual reproduction in paramecia, a single paramecium becomes two new paramecia. The genetic material of the new paramecia is usually —identical to the originalhalf the amount of the originaldouble the amount of the originalsimilar to the original
- 6. Multiple ChoiceCompared with the genetic material of the original cell in the diagram above, each of the two new cells contains —half the genetic material of the parent celltwice as much genetic material as the parent cellgenetic material that is identical to the parent cellnew genetic material that is different from that of the parent cell
- 7. Multiple ChoiceWhich of these occurs in sexual reproduction but not in asexual reproduction?Genes carry genetic information.An offspring is made of cells.Cells from two organisms combine.An offspring inherits a set of traits.
- 8. Multiple ChoiceWhich of the following is an advantage of sexual reproduction over asexual reproduction?It allows the offspring species to look just like the parent species.It ensures that all offspring will survive if disease strikes.It makes species more able to adapt to environmental changes.It passes genetic information from one parent to one offspring.
- 9. Multiple ChoiceThe picture below shows yeast budding. Yeast reproduce asexually by budding, a process in which a bud breaks off the original yeast cell.Which of the following best describes a yeast bud?A yeast bud is genetically identical to the original yeast cell.A yeast bud contains genetic material from its two parents.A yeast bud has half as much genetic material as the original yeast cell.A yeast bud has different mutations from the original yeast cell.
- 10. Multiple ChoiceOrganisms will pass down inherited traits to their offspring through the genetic material contained within the nucleus of their cells. Which of the following examples best illustrates this fact?A crop of corn will be eaten by insects unless they are sprayed with pesticides.An older dog is discovered to have liver cancer.A mother with a recessive trait for color blindness will always pass down color blindness to her offspring.rse breeders will choose strong, fast, healthy horses to breed.
- 11. Multiple ChoiceThe graphic below shows an unlabeled animal cell. In which location would genetic material most likely be found?1234
- 12. Multiple ChoiceThree 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?Genes, chromosomes, and nucleusCytoplasm, chloroplasts, and genesVacuoles, nucleus, and chromosomesChromosomes, chloroplasts, and vacuoles
- 13. Multiple ChoiceWhich sentence best describes the relationship between genes and chromosomes?Genes are found within chromosomes.Genes and chromosomes are the only things that form the nucleus.Several chromosomes make up one gene.Several genes are attached to different parts of the Golgi apparatus.
- 14. Multiple ChoiceWhich of the following explains a difference between genes and chromosomes?Chromosomes are made up of genetic material, and genes are made up of only proteins.Genes determine a person's specific traits, and chromosomes hold the genes.Genes are found in the nucleus, and chromosomes are found in the cell wall.Chromosomes determine a person's traits, and genes hold the chromosomes
- 15. Multiple ChoiceThe ability to roll one's tongue is an inherited trait. Which of the following is responsible for a person having this trait?The genetic instructions in one's chromosomesThe environmental influence of family membersThe DNA inside an individual's brainThe ability for an individual to teach him or herself
