Across
  1. 2. - An inherited trait that helps an organism survive in its specific environment.
  2. 5. - The monomer of DNA consisting of a sugar, phosphate, and base.
  3. 8. - When an organism has two of the same alleles for a trait (e.g., TT or tt).
  4. 9. - A process that requires oxygen to produce energy.
  5. 12. - The passive movement of particles from high to low concentration.
  6. 13. - When an organism has two different alleles for a trait (e.g., Tt).
  7. 15. - The organelle where the Krebs cycle and electron transport chain happen.
  8. 16. - A complex cell that contains a nucleus; you are made of these.
  9. 17. - The process of maintaining a stable internal environment despite external changes.
  10. 20. - The first step of cellular respiration that happens in the cytoplasm.
  11. 21. - Different
  12. 23. - A change in the genetic sequence that can be beneficial, harmful, or neutral.
  13. 25. - A pattern where both traits show up at the same time, like a speckled chicken.
  14. 26. - The change in the inherited traits of a population over many generations.
  15. 28. - The "survival of the fittest" mechanism that drives evolution.
  16. 30. - Movement of molecules against the gradient that requires ATP.
  17. 31. - A protein catalyst that speeds up reactions by lowering activation energy.
Down
  1. 1. - The process of copying DNA into a strand of mRNA.
  2. 3. - Cell division that results in four unique haploid daughter cells.
  3. 4. - Cell division used for growth and repair that results in two identical diploid cells.
  4. 6. - The process of converting light energy into chemical energy in the form of glucose
  5. 7. - The physical appearance or trait expressed by an organism.
  6. 10. - A simple cell that lacks a nucleus and membrane-bound organelles.
  7. 11. - The site of protein synthesis that can be free-floating or attached to the ER.
  8. 14. - Using the mRNA code to build a chain of amino acids.
  9. 18. - The specific term for the movement of water across a semi-permeable membrane.
  10. 19. - The organelle where the Calvin Cycle takes place
  11. 22. A long chain of amino acids linked by peptide bonds; this is what becomes a functional protein after folding.
  12. 24. - The actual genetic makeup or "letter" combination of an organism
  13. 27. - A process that occurs when oxygen is absent, like fermentation.
  14. 29. - The main component of the cell membrane with a "hydrophilic" head and "hydrophobic" tail.
