BIO II: Midterm

Reasons that viruses are considered to be nonliving is because

• They are not cellular
• They cannot reproduce on their own
• They cannot make proteins
• all of the above

What do viruses need to reproduce?

• they need genetic material
• They need a host cell
• They need  bacteria
• They need insulin

A(n) _____ is a virus that enters a bacterial cell.

• endospore
• decomposer
• plasmid
• bacteriophage

When a virus invades a living cell, its _______
takes over the cell's functions.

• core
• cytoplasm

What provides direct energy for the virus?

• food
• its host
• the sun
• a parasite

Viruses are cells. 

• True 
• False

Which of the following occurs after a virus attaches to a host cell in the viral reproduction process?

• The host cell dies
• The virus dies
• The virus inserts its genetic information into the host cell
• copies of the virus are immediately released from the host

What is the first step to both viral cycles?

• The virus attaches to a host

• the virus injects genetic material

• the host gets sick

• the cell is destroyed

What is shown here?

• Lysogenic Cycle
• Lytic Cycle
• Binary Fission
• Conjugation

What process is this?

• phagocytosis
• lytic cycle
• lysogenic cycle
• formation of antibodies
