So, most of you that attended the sixth period "lab" will have begun this open-book test that is homework with a perfect 5 of 5 correct. Now let's see you continue this standard! Don't guess at any part of the question..understand the terms or look them up till you do...or ask me. Stay proud of the work you do...after all it tells what type of person you are. Question #1: The best scientific explanation for differences in structure, function and behavior found in different species of organisms is provided by: (A) carbohydrate electrophoresis (B) population chromatography (C) the theory of carrying capacity (D) the theory of evolution Question #2: Many animals exist today in a form that is almost identical to the form they had a million years ago. What is the most probable explanatin for this lack of evolutionary change? (A) genetic mutations have occurred among these animals (B) the environment of these animals remained about the same (C) these animals reproduce by sexual reproduction (D) complex organisms evolved into simpler ones Question #3: Throughout the history of Earth, which factor has probably been the chief cause of the extinction of various species? (A) people's interference with nature (B) failure to adapt to environmental changes (C) warfare within the species (D) volcanic eruptions Question #4: A trait with low survival value to the members of a population will most likely (A) undergo a series of mutations in succeeding generations (B) cause the reproductive rate of the individual to increase (C) decrease in frequency from one generation to the next (D) remain unchanged in frequency through many generations Question #5: How might the lack of genetic diversity found in populations of endangered species hinder their recovery?
