Question 1

Bacteria

Answer 1

A prokaryotic organism

Question 2

Cocci

Answer 2

Small circular clusters of bacterial cells they look like berries

Question 3

Bacilli

Answer 3

Rod shaped bacterial cells

Question 4

Spirochetes

Answer 4

Spiral shaped bacteria

Question 5

Binary fission

Answer 5

Enables prokaryotes to reproduce very quickly in the right conditions, a cell basically splits in half after the DNA inside splits and moves to opposite ends of the cell

Question 6

Rapid reproduction

Answer 6

Bacteria divides every twenty mins

Question 7

Transformation

Answer 7

The bacteria absorbs DNA from the environment

Question 8

Conjugation

Answer 8

Two bacterial cells temporarily join and transfer genetic material

Question 9

Transduction

Answer 9

Viruses carry genes from one cell and inject them into another

Question 10

Endospore formation

Answer 10

A cell forms an outer cover In harsh conditions and sort of goes into hibernation,

Question 11

Cyanobacteria

Answer 11

Generates oxygen as a was waste product, possible the earth use to be anaerobic and is now aerobic

Question 12

Answer 12

The use of organism to remove pollutants from air, water, and soil

Question 13

Pathogens

Answer 13

Bacteria and other micro organisms that cause disease

Question 14

When and what is an antibiotic used on

Answer 14

During a cold

And on a bacteria not a virus

Question 15

Lytic cycle

Answer 15

A virus completely takes over bacteria and releases more viruses throughout the body resulting in illness

Question 16

Lysogenic cycle

Answer 16

The viral DNA has been injected into the cell, adds itself in with the host cells DNA but it does not cause you to get sick, it goes into a dormant sleeping state

Question 17

Retrovirus

Answer 17

HIV is a retrovirus because normally it goes DNA to RNA well it does reverse translation and synthesizes DNA from RNA

Question 18

Vaccines

Answer 18

Used to prevent a virus, but does not always work, they are small pieces of deactivated pathogens that stimulate the immune system to protect against actual pathogens
