7
Q

A _______ is any inanimate object that can be used to spread disease.

A

fomite

8
Q

The pathogen is deposited directly into the blood stream, into tissue below the skin, or into mucous membranes.

(The microbe gets injected directly into the bloodstream)
(arthropod vectors) (mosquitoes)

A

Parenteral route

9
Q

______ are only found on the surfaces of viruses, and are glycoprotein spikes that are specialized receptors that allow the virus to firmly attach to the host.

A

Peplomers

10
Q

Glycoprotein spikes would play a primary role in _______.

A

colonization

11
Q

Due to binary fission, the host now has a large population size of microbes and it is difficult for the immune system to control the spread of the microbes within the body (dissemination). What is the name that describes this situation?

A

Establishment

12
Q

A.) Apoptosis
B.) Necrosis

A

B.) Necrosis

13
Q

The cell dies, but the plasma membrane stays intact.
A.) Apoptosis
B.) Necrosis

A

A.) Apoptosis
