5 Written questions

5 Matching questions

  1. Anagenesis
  2. RNA
  3. Inheritance of acquired Characteristics
  4. Speciation
  5. Sex Chromosome
  1. a the hypothesis that organisms' bodies change during their lifetimes by use and disuse and that these changes are inherited by their offspring
    - Traits developed during a parent's lifetime could be passed to their offspring
  2. b the formation of new species as a result of evolution
  3. c ribonucleic acid; a nucleic acid that plays an important role in the production of proteins
  4. d (genetics) a chromosome that determines the sex of an individual
  5. e A pattern of evolutionary change involving the transformation of an entire population, sometimes to a state different enough from the ancestral population to justify renaming it as a separate species; also called phyletic evolution.

5 Multiple choice questions

  1. A stressful period in which few organisms of a population survive, resulting in loss of genetic variation in the population.
  2. Written by Charles Lyell, argued that geological processes observed in the present are the same as those that occured in the past
  3. in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes
  4. evolution resulting from small specific genetic changes that can lead to a new subspecies
    - evolution on the smallest scaleā€”a generation-to-generation change in the frequencies of alleles within a population
  5. an organic compound that is made of one or more chains of amino acids and that is a principal component of all cells

5 True/False questions

  1. PlieotrophyThe physical traits that appear in an individual as a result of its gentic make up.


  2. Systematicschange in a DNA sequence that affects genetic information


  3. Alfred Russel Wallace(The Origin of Species) a British naturalist, explorer, geographer, anthropologist and biologist. He is best known for independently proposing a theory of evolution due to natural selection that prompted Charles Darwin to publish his own theory.


  4. Homologysimilarity between two species that is due to convergent evolution rather than to descent from a common ancestor with the same trait


  5. Forces of Evolution1. Mutation- changes in genetic code (source of new genetic diversity)
    2. Migration- new traits are present (outsider comes in to breed)
    3. Natural Selection- higher chance of surviving allows for more offspring
    4. Random Genetic Drift- chance events/ changes, common in small populations
