Across
  1. 2. This process condensed chromatin into a tightly coiled chromosomes and the nuclear membrane breaks down
  2. 4. This organelle holds genetic information to build proteins
  3. 7. This happens when both organisms benefit
  4. 9. This is long term energy, makes up cell and membrane insulation
  5. 10. This is when one organism is helped and the other is unaffected by the relationship
  6. 14. This is a structures in organisms that have similar structures but different functions
  7. 15. This process occurs in the mitochondria and is the creation of ATP energy
  8. 16. This lower the activation energy to speed up reactions and are considered catalyst
  9. 17. This process adds a nucleotide to a DNA chain
  10. 18. This happens when one organisms is helped and the other organism is hurt
  11. 19. This is where pollen travels down and fuses with the ovule
  12. 20. This builds up hair,skin,and nails and involves in enzymes
Down
  1. 1. This process happens when spindle fibers pull the sister chromatids to opposite sides of the cell
  2. 3. This process does not require ATP, with the concentration for high to low
  3. 5. This organelle makes energy and is the site of cellular respiration
  4. 6. This contains no organelles or internal structures and injects genetic material into a host cell
  5. 8. This is when a nucleotide is removed
  6. 11. This process requires ATP, against the concentration from low to high
  7. 12. This process is a period of slow change interrupted by periods of rapid change with few, if any, transitional fossils
  8. 13. This process occurs in the chloroplast and conversion of solar energy into glucose
