Across
  1. 1. Produces four non-identical gametes (sperm or egg) with half number of chromosomes
  2. 3. Organisms that have both male and female reproductive organs
  3. 5. Programmed cell death
  4. 7. Produces two identical daughter cells for growth, repair, and asexual reproduction (prophase, metaphase, anaphase, and telophase)
  5. 9. The process by which new species form. It occurs when groups in a species become reproductively isolated and diverge
  6. 10. A process that results in changes in the genetic material of a population over time
  7. 12. Involves one parent and produces genetically identical offspring
  8. 13. A physical or behavioral trait of an animal that helps them better survive in their environment
  9. 15. The cytoplasm divides, creating two daughter cells
  10. 18. A process where organisms with traits that are best suited for their environment are more likely to survive and reproduce
  11. 19. Individuals in a species have different traits
  12. 20. Organisms compete for resources like food, mates, and shelter
Down
  1. 2. Cells complex cells with a nucleus and membrane-bound organelles. For example: plant, animal, and fungi cells
  2. 4. How scientists construct scientific names for organisms For example Species are given two word names:Canis familiaris   dog
  3. 6. An organism's ability to pass its genetic material to its offspring
  4. 8. Measures the concentration of salt in water (usually in parts per thousand)
  5. 11. the science of classifying organisms based on their anatomy, chemical makeup,ancestry, and embryology
  6. 14. Cells simple cells that don't have a nucleus or membrane-bound organelles. For example: bacteria
  7. 16. Involves two parents and combines their genetic material to create offspring
  8. 17. The cell grows and prepares for division ( G1, S, and G2 phases)
