  1. 1. The shape of a protein as determined by the genetic code of an organism.
  2. 4. A neutral trait will remain relatively the ___________ in a population.
  3. 6. A change over many generations in the distribution of inherited traits in a population that causes organisms in the population to be better able to reproduce.
  4. 7. A group of organisms of a species living in the same environment over time.
  5. 10. A random and permanent change to a genetic material in a gene. Mutations to genetic material are rare in nature.
  6. 12. The way that related traits are divided in a population of organisms.
  7. 15. Large complex molecules that are responsible for traits. They make up the structure and control most functions and chemical reactions in living cells.
  8. 16. Selection: The process by which individual organisms with traits that are beneficial in their environment are more likely to survive and produce more offspring.
  9. 18. A less beneficial or harmful will ___________ in a population.
  10. 20. A group of organisms that are physically similar and can reproduce with each other to produce offspring.
  11. 21. A characteristic of an organism; many traits are inherited (genetic).

  1. 2. The ability to not be affected by something that is normally harmful.
  2. 3. The job a protein does based on the shape of the protein.
  3. 5. ______________ Conditions are variables in the environment such as food and water availability, water quality, temperature, air quality, topography, habitat, and natural hazards.
  4. 8. A ____________ trait will positively influence an organism's chance of survival and reproduction.
  5. 9. A ____________ trait will not influence an organism's chance of survival and reproduction.
  6. 11. A beneficial trait will ___________ in a population.
  7. 13. A ____________ trait will negatively influence an organism's chance of survival and reproduction.
  8. 14. The chances or likelihood that something will happen.
  9. 17. A sequence of DNA that determines the structure of a protein. The combination of genes on the chromosomes determines what proteins are made in the cell.
  10. 19. When a trait is able to be passed from parent to offspring.
