Knowledge Checks

• Which feature helped some medium ground finches survive the drought?

  Large, deep beaks
• Did Darwin observe natural selection?

  No
• Can you predict which features will be beneficial if you know how the environment will change? In other words, do you think you could predict which finches would survive if there was another drought on Daphne Major?

  Yes
• What feature did the medium ground finch vary in that was critical to the Grants research?

  beak depth
• Which finches had more offspring following the El Nino event?

  Finches with smaller beaks
• How many different species of finches inhabit the Galapagos?

  13
• During the drought, what was the main food available on Daphne Major?

  Seeds
• In light forest environment, which moths are more likely to survive? (light peppered moths, dark peppered moths, both?)

  light peppered moths
• Bipedal walking (walking on two legs) is a more energetically efficient form of locomotion than quadrupedalism (walking on four legs).

  Is this statement falsifiable?

  Yes
• It will rain in New York City in 1,000,000 years.

  Is this statement falsifiable?

  No
• There is a tiny China teapot that orbits the sun between the Earth and Mars. It is so small that even the most powerful telescopes cannot see it.

  Is this statement falsifiable?

  No
• An alien spaceship crash landed in New Mexico.

  Is this statement falsifiable?

  No
• Is natural selection predictable in the sense that you can predict what will happen to individuals if you know the environment they are in and the fitness of the individual in the environment?

  Yes
• If a scientist completed an experiment and they did get the result they predicted they would have based on their hypothesis, how would the scientist phrase their result?

  My hypothesis has failed to be rejected.
• Define the word "hypothesis".

  A provisional explanation for a particular question.
• What are the three conditions required in a population for natural selection to function as a force of evolution?

  1. variation of traits
  2. traits are heritable
  3. competition leading to differential reproductive success
• In a dark forest environment, which moths are more likely to survive: dark peppered moths, light peppered moths, or both?

  dark peppered moths
• What are the 3 components of a nucleotide?

• What is the process when a protein-coding DNA sequence is copied into an RNA molecule?

  Transcription
• What is the correct complement to this DNA strand:

  AGTCGGATTTGA

  TCAGCCTAAACT
• What is the process in which mRNA serves as a template for protein production?

  Translation
• Transcription takes place where?
