Biology Semester Final

  1. What is homeostasis
    The maintenance of content internal conditions in an organism
  2. The 3 major characteristics of all living things share
    Metabolism. Genetic material-DNA
  3. What is a hypothesis
    Educated guess, testable, explains something about the natural world
  4. The 3 steps of the scientific method
    Questions, hypothesis, controlled experiment
  5. What is the carbohydrates monomer
    Monosaccharides or glucose
  6. Proteins function
    Increase the speed of a reaction, make muscle,etc
  7. The differences between eukaryotes and prokaryotes
    • E: plant/animal cells, fungus, has nucleus
    • P: no nucleus, only single stranded called, microscopic
  8. Active transport
    Needs energy
  9. Passive transport
    Doesn't need energy
  10. Semi-permeable membrane
    Cell membranes allow are materials through while others are not
  11. Mitosis 1/ result
    Long interface/ 2 somatic cells
  12. Meiosis/ result
    2 round of cell division/ 4 gametes
  13. How many pairs of chromosomes
  14. How many pairs of autosomes
  15. Phenotype
    The physical characteristics
  16. Genotype
    The genie make up
  17. What is DNA polymerase
    Bonds the new nucleotides together
  18. What is semi conservative replication
    Uses of one strand and one old strand
  19. Central dogma
  20. Function of carbohydrates
    To be broken down to provide a source of usable chemical energy for cells
  21. What is the difference between acid and base
    • Base: compounds that remove H+ ions from solution
    • Acid: a compound that release a proton when it dissolves in water
  22. What are enzymes
    Catalyst for chemical reaction the living things
  23. Why are enzymes important
    It lowers the activation energy and increases the rate of chemical reactions
  24. What are the three principles of cell theory
    All organisms are made of cells. All existing cells or are produced by other living things. The sale is the most basic unit of life
  25. Osmosis
    Diffusion of water molecules across the semi Premable membrane from an area of high water concentration to an area of lower water concentration
  26. Diffusion
    Movement of dissolved molecules and fluid or gas from a region of higher concentration to a region of lower concentration
  27. phospholipids
    Molecule that forms the cell membrane
  28. Crossing over
    Exchange of chromosome segments between homologous chromosomes during meiosis one
  29. Law of segregation
    Organisms inherit two copies of jeans one from each parent. Organisms donates only one copy of each gene and there is gametes.
  30. What is the difference between sex chromosomes and autosomes
    • Auto: chromosome that contains genes for characteristics not directly related to the sex of the organism
    • Chrome: Long continuous thread of DNA that consist of numerous genes and information
  31. What is the difference between haploid and diploid cells
    • D: A cell that has two copies of each chromosome
    • H: A cell that has only one copy of each chromosome
  32. Homozygous
    Terroristic of having two of the same alleles at the same locus of sister chromatids
  33. Heterozygous
    Characteristics of having two different alleles that appear at the same locus of sister chromatids
  34. Dominant
    Allele that is expressed when two different alleles are present in the organisms genotype
  35. Recessive
    Allele that is not expressed unless two copies are present in an organisms genotype
  36. Incomplete dominance
    Heterozygous phenotype that is a blend of two homozygous phenotypes
  37. Sex linked traits
    Gene that is located on a sex chromosome
  38. Polly genic traits
    Trait that is produced by two or more genes
  39. What are the monomers of DNA called
  40. What are the three differences between DNA and RNA
    • You're so instead of thymine, ribosomes instead of deoxyriose
    • Single strands
  41. Where in the cell does transcription occur
  42. Where in the cell does translation occur
