  3. 11. Also called: primary producer, producer, or PLANT. The beginning of a food chain
  4. 12. nonliving parts of the environment (i.e. temperature, soil, light, moisture, air currents
  5. 13. The fertilized egg that has one set of alleles from mom and one set from dad. It is a diploid cell
  6. 14. Differences in the sequences of genes between individuals. This is what makes organisms of the same species look different from each other.

  14. 29. the three nucleotide sequence on a mRNA molecule that codesfor one amino acid.
  15. 30. regulation of an organism’s internal environment to maintain conditions needed for life.
  16. 31. The genetic makeup of an organism •The two alleles inherited for a particular gene
  17. 32. a taxonomic group that includes multiple species that are closely related and share common characteristics
  18. 33. Differences in the sequences of genes between individuals. This is what makes organisms of the same species look different from each other.

  7. 9. substance that is able to kill or inhibit the growth of bacteria.
  8. 10. Passing of traits from parents to child •Genes on chromosomes control the traits that show up in an organism
  9. 15. Fat tissues that help keep an organism warm.
  10. 16. the plural for nucleus
  11. 17. The four steps that a cell goes through in order todivide. Growth, replicating DNA, growing again, and actually dividing
