Grade 10 Microbiology
In a lysogenic cycle, a virus enters the host cell, makes copies of itself, and then destroys the cell to release the new viruses.
  1. True
  2. False
Grade 10 Microbiology
Eukaryotics cells have mesosomes.
  1. True
  2. False
Grade 10 Microbiology
A virus cannot reproduce on its own therefore it is not really a living thing.
  1. True
  2. False
Grade 10 Microbiology
Which of these causes the common cold?
  1. bacterium.
  2. virus.
  3. protozoan.
  4. yeast.
Grade 10 Microbiology
Prokaryotes are single-celled organisms that do not have membrane bound organelles. They generally are found in three shapes. They are            bacillus           , a rod shape,          coccus         , a sphere shape, and a spiral shape, called             spirillum            .
Grade 10 Microbiology
Most bacteria have extra pieces of DNA called            plasmids           . These small, circular DNA segments are replicated                 independently                 and can be               transferred               between cells.
Grade 10 Microbiology
The outer protein coat of a virus is a                   .
  1. core of DNA.
  2. core of RNA.
  3. capsid.
  4. membrane envelope.
Grade 10 Microbiology
Which viral reproductive cycle causes release of viruses to environment (reads the virus genetic material and makes copies of genes and builds capsids and then assembles new viruses until they escape)?
  1. lysogenic
  2. lytic
  3. lysomes
Grade 10 Microbiology
If a bacterium cannot move it is missing             flagellum            .
Grade 10 Microbiology
Which disease is Infectious?
  1. Allergies
  2. HIV
  3. Asthma
  4. Diabetes
Grade 10 Microbiology
Viruses are a                .

  1. DNA or RNA.
  2. a liquid membrane.
  3. cytoplasm.
  4. a flagellum.
Grade 10 Microbiology
Viruses are cells.
  1. True
  2. False
Grade 10 Microbiology
The structure around a virus is called a                .
  1. membrane
  2. wall
  3. capsid
Grade 10 Microbiology
This viral life cycle is when virus genetic material is integrated with the cell’s info (viruses trick the cell into taking them inside where they will trick the cell into expressing viral genes that code those proteins that make up the virus, reproducing itself ).
  1. lysogenic
  2. lytic
Grade 10 Microbiology
Which group(s) of microorganisms is (are) thought to be the oldest living organisms?
  1. eukaryotes
  2. heterotrophic prokaryotes
  3. viruses
  4. autotrophic prokaryotes
Grade 10 Microbiology
Bacteria often contain small circular molecules of DNA known as                     .
  1. clones.
  2. restriction enzymes.
  3. plasmids.
  4. hybrids.
Grade 10 Microbiology
Viruses are not alive because                                                   .
  1. rely on cells to carry out many of their functions
  2. can’t reproduce on their own
  3. can't move
Grade 10 Microbiology
Viruses are                 than cells.
  1. larger
  2. smaller
