Biology Exam, Semester 2

  1. What is how far a wave gets from the midline?
  2. What is how many waves pass through a certain portion in one second?
  3. What is the distance from one point on a wave to the same point on the next wave?
    Wave length
  4. Image Upload 1
  5. Long wave lengths have low energy small frequency.
  6. Short wavelengths have high energy and high frequency.
  7. Image Upload 2
  8. What are some differences between DNA and RNA?
    • DNA: Deoctribose, double stranded, large, g-c-t-a, promotes TAC.
    • RNA: Ribose, single stranded, small, g-c-u-a, Promotes UAG.
  9. What is transcription?
    It is the process of transcribing or making a copy of genetic information stored in a DNA strand into acomplementary strand of RNA (messenger RNA or mRNA) with the aid of RNA polymerases.
  10. What is translation?
    A step in protein biosynthesis wherein the genetic code carried by mRNA is decoded to produce the specific sequence of amino acids in a polypeptide chain. The process follows transcription in which the DNA sequence is copied (or transcribed) into an mRNA.
  11. What are the tree types of mutations?
    Addition, Substitution, Deletion
  12. What is the definition of probability?
    The likely hood of something to happen.
  13. What is Homozygous?
    Two similar characteristics( AA, aa)
  14. What is Heterozygous?
    Two different characteristics(Aa)
  15. What does the Excretory System do?
    Pulls waste from blood that was filled with drinking fluids.
  16. What does the endocrine do?
    Monitors blood level, flight or fight situation, insulin and glucose.
  17. What is the order in Ecology?
  18. How does random sampling work? and why is it done?
    You randomly select papers or have a computer generator pick randomly, and it is done to take biased out of choosing.
  19. What are 3 large biomes?
    Desert, grassland, trop. rain forest.
