Helpful bacteria:

  1. How do bacteria “decompose” dead organic matter?

DIGESTION, BREAK DOWN USING DIGESTIVE ENZYMES (EAT)

  1. Based on the diagrams below, explain the difference between nitrifying bacteria and denitrifying bacteria?

NITRIFCATION CONVERTS AMMONIA INTO NITRATES THEN NITRATES

DENITRIFICATION CONVERTS NITRATES INTO ATMOSPHERIC NITROGEN

33.How is a protist different from bacteria?

BACTERIA= PROKARYOTE, NO NUCLEUS OR MEMBRANE BOUND ORGANELLES

PROTIST= EUKARYOTE, HAVE NUCLEUS

34.In 1928,FrederickGriffithestablishedthereisatransformingprincipleinbacterialgenetics. Later on, we learn that the transforming principle is DNA and that bacterial cells are capable of transferring genetic material from one cell toanother. Explain how this illustration shows this concept.

YOU CAN TURN BENIGN (NON-DEADLY) BACTERIA AND TRANSFORM IT INTO LETHAL (DEADLY) BACTERIA BY GIVING IT THE DNA CODE FOR LETHAL DNA.

BASICALLY, IF YOU GIVE BACTERIA INSTRUCTIONS TO BE DEADLY, IT CAN BECOME DEADLY.

/

20.Genus + species nomenclature

BACTERIA

35.Draw and label the parts of a virus: genetic material, antigen, envelope, and capsid.

  1. How does mutation increase viral diversity?

DIFFERENT DNA MAY RESULT IN NEW PROTEINS THAT PRODUCE DIFFERENT ANTIGENS. CAN GET INTO NEW HOSTS CELLS

  1. Explain in your own words how the avian flu and swine flu were able to infect humans. Why have we not seen dog flu break-outs in humans yet?

AVIAN AND SWINE INFLUNENZA OBTAINED ANITGENS TO BIND TO HUMAN RECEPTORS. THEY CAN ENTER HUMAN HOST CELLS FOR VIRAL REPLICATION.

DOG FLU DOES NOT HAVE ANTIGENS TO ENTER HUMAN CELLS.

38.Write the descriptions under the correct drawing.
