  2. 7. The kind of solution that has a higher solute concentration than the cell in it
  3. 9. mRNA is made into proteins
  4. 11. Asexual reproduction in stressful times
  5. 15. The diffusion of water
  6. 20. Where the proteins are made
  7. 21. A solution with the same solute concentration as the cell floating in it

Down
  1. 1. A phosphate group, a sugar, and a base
  2. 2. Division of somatic cells
  3. 4. Males, in chromosome form
  4. 5. In addition to DNA, these too must be copied before mitosis
  5. 6. Cell division resulting in gametes
  6. 8. A phenotype that develops with incomplete dominance
