Diseases, bacterial reproduction and viral reproduction

What is a communicable disease?

• A disease that cannot be spread person to person.

• A disease that is inherited

• A disease that can be spread from person to person.

• A disease that can be passed from parent to offspring

What is a non-communicable disease?

• A disease that cannot be passed on to another person.

• An illness that can be passed on by germs from person to person.

• Disease that is inherited

• Disease that is passed from parent to offspring

This type of pathogen is a one-celled living thing in which most are harmless but a few can cause illnesses like pinkeye, strep throat, and ear infections.

• virus

• fungi

• bacteria

• Parasite

True or False: Animals such as insects and birds do not spread pathogens to people

• true

• false

Cancer, heart disease, and diabetes are examples of:

• communicable diseases

• zoonotic diaereses

• infectious diseases

• non-communicable diseases

Colds, flu, chicken pox, and viruses are examples of:

• zoonotic diseases

• non-communicable diseases

• non-infectious

• communicable diseases

Bacteria reproduce this way.

• Budding

• fragmentation

• binary fission

• vegetative propagation

Binary fission is a type of

• propagation

• sexual reproduction

• asexual reproduction

• fragmentation

In order for a bacterial cell to divide, which of the following must occur?

• Circular DNA replicates

• Cell wall starts to break down

• Both of these are correct

• Neither of these are correct.

In binary fission, all of the following occur

EXCEPT...

• there is an increase in the number of bacterial cells

• the bacteria cell invades a host cell

• the resulting cells are genetically identical to the original cell

• only one parent cell was involved at the beginning
