Adenoviruses...(2 correct answers)
- A.
  
  Cause hemorrhagic fever
- B.
  
  Cause the common cold
- C.
  
  Are (+) strand RNA viruses
- D.
  
  Are large DNA viruses
- E.
  
  Are small DNA viruses
Correct Answer(s)
B. Cause the common cold
D. Are large DNA viruses

Explanation
Adenoviruses are responsible for causing the common cold, which is a viral infection that affects the upper respiratory system. Additionally, adenoviruses are classified as large DNA viruses, as they have a double-stranded DNA genome. These characteristics make adenoviruses distinct and enable them to replicate and cause infections in humans.

Hantavirus is a...(2 correct answers)
- A.
  
  (+) strand RNA virus
- B.
  
  Bunyavirus
- C.
  
  Orthomyxovirus
- D.
  
  Small DNA virus
- E.
  
  (-) strand RNA virus
Correct Answer(s)
B. Bunyavirus
E. (-) strand RNA virus

Explanation
Hantavirus is classified as a Bunyavirus and a (-) strand RNA virus. Bunyaviruses are a family of viruses that have a segmented genome consisting of three RNA strands, one of which is negative-sense. Hantaviruses are part of this family and also have a negative-sense RNA genome. This means that the genetic material of Hantavirus is complementary to the mRNA and needs to be transcribed into a positive-sense RNA before it can be translated into proteins. Therefore, the correct answers are Bunyavirus and (-) strand RNA virus.
