Across
  1. 2. threadlike structures made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell
  2. 5. having two identical versions of a gene, or alleles, for a particular trait
  3. 6. the genetic makeup of an organism
  4. 7. the variety of life on Earth, including all living things and their interactions
  5. 9. a relationship between two organisms where one organism, the parasite, benefits at the expense of the other, the host
  6. 10. a form of glucose, a main source of energy that your body stores primarily in your liver and muscles
  7. 12. the deliberate breeding of two organisms to combine their genetic material in their offspring
  8. 17. a biological science that studies the relationships between living things and their environment
  9. 19. the process by which plants, algae, and some bacteria use sunlight, water, and carbon dioxide to create oxygen and chemical energy stored as sugar (glucose)
  10. 20. the gradual change in the species composition of an ecological community over time, where one set of organisms is replaced by another following a disturbance, leading to a new community with different dominant species
  11. 21. a term used to describe the scientific study of how living organisms function
  12. 24. a cellular structure found in all cells, responsible for protein synthesis by translating the genetic code carried by messenger RNA (mRNA) into a chain of amino acids, which then fold to form proteins
  13. 25. the main sugar found in your blood
  14. 27. a trait or allele of a gene that is expressed even when only one copy is present in an individual
  15. 28. the process of growing microorganisms, like bacteria or yeast, or human, plant, or animal cells and tissues in a controlled laboratory environment for study or research purposes
Down
  1. 1. a signaling molecule that regulates physiology and behavior in multicellular organisms
  2. 3. the observable physical characteristics of an organism
  3. 4. the chemical process by which living organisms break down glucose (sugar) to release energy in the form of ATP
  4. 8. ribonucleic acid
  5. 11. a process that causes species to evolve over time
  6. 12. a biological process where species affect each other's evolution through natural selection
  7. 13. an organic molecule that includes carbohydrates, protein, lipids, and nucleic acids
  8. 14. an organism has two different alleles for a specific gene
  9. 15. an initial measurement taken at the beginning of a study or experiment
  10. 16. refers to the relationship between an observed trait and the two inherited versions of a gene related to that trait
  11. 18. the basic unit of heredity
  12. 22. the change in frequency of an existing gene variant in the population due to random chance
  13. 23. one of multiple alternative forms of a gene at a specific location on a chromosome
  14. 26. deoxyribonucleic acid
