  1. 2. a highly contagious upper respiratory disease caused by the SARS-CoV-2 virus.
  2. 3. a specific sequence of DNA located on a chromosome. Contains the instructions to make a specific protein, creating an organism’s traits.
  3. 5. the three nucleotide sequence on a mRNA molecule that codes for one amino acid.
  4. 9. the place in which an organism lives out its life
  5. 11. specialized structure that carries out a specific cell function in different parts of the cell at the same time.
  6. 12. The ability of an organism to survive in its environment long enough to reproduce
  7. 14. a virus that attacks the immune system, specifically the white blood cells.
  8. 15. A substance used for destroying insects or other organisms. Overuse can kill beneficial organisms in the soil. Overuse can runoff into rivers and streams killing beneficial organisms in the water.
  9. 20. microscopic, unicellular organism without a nucleus or other membrane-bound organelles.

  1. 1. plant structure that develops into a seed when fertilized.
  2. 4. body system that functions as a communication system and includes the pituitary gland, the thyroid gland, the parathyroid gland, the thymus gland, the pineal gland, the pancreas, the adrenal glands, the ovaries, and the testes.
  3. 6. the central membrane-bound organelle that manages cellular functions and contains DNA.
  4. 7. one of a pair of cells that function in the opening and closing of a plant’s stomata by changes in their shape.
  5. 8. the mRNA carries genetic information to the ribosomes. The Ribosomes use this information to form proteins. We use a codon chart to help us figure out what proteins are made.
  6. 10. nonliving parts of the environment (i.e. temperature, soil, light, moisture, air currents)
  7. 13. a specific characteristic of an organism. Such as eye color, height, etc.
  8. 16. the slow, gradual genetic change in an entire population of organisms over time…a looooooooong time!
  9. 17. a change in the nucleotide sequence of an organism’s DNA. May happen due to an error during replication or exposure to damaging agents.
  10. 18. an organism that is infected with or fed upon by a parasitic or pathogenic organism.
  11. 19. a taxonomic group that includes multiple species that are closely related
