A) A mother passes a mutated gene to her offspring B) A person handles contaminated tissues and later gets a cold C) A healthy mother passes protective antibodies to her unborn child D) An infected raccoon bites an uninfected dog who contracts (gets) Rabies _____ 10. What relationship exists between a virus and a cell? A) A cell needs a virus to obtain energy B) A cell cannot exist without a virus C) A virus is bigger than a cell D) A virus needs a host cell to reproduce _____ 6.

A) A virus is a prokaryotic microbe B) A virus requires a host cell to reproduce C) A virus is a eukaryotic microbe D) A virus moves by cilia or flagella _____ 15. If a person is suffering from a severe infection caused by bacteria, which solution might a doctor propose? A) Antibiotics C) Surgery B) Exercise D) Vaccination _____ 16. The disease Strep Throat is caused by a bacterial infection. The infected person carries the germs in the mouth and nasal fluid. Symptoms can include a high fever, a sore throat, and a skin rash. Which action could spread the disease? A) Washing hands properly with soap B) Using tissue for coughing and sneezing C) Allowing an infected person to attend school D) Keeping separate utensils for the infected person _____ 17. How is the Rabies virus transmitted (spread) from one organism to another? A) Exposure to the saliva of an infected organism, usually through a bite B) The virus is airborne and can be inhaled from a cough or sneeze from an infected organism C) Consumption of undercooked meat D) The virus is genetically linked and is passed from mother to child Vocabulary: Carefully read each definition and match it to the correct word. _____ 18.
