Answer 1

no nucleus, unicellular

Question 2

Answer 2

tetanus, lymes disease, bronchitis, terbuculosis, and strep throat

Question 3

Compare and contrast Eubacteria and Archaea

Answer 3

Eubacteria is found everywhere while Archaea is found in extreme environments

Question 4

What type of cell has peptidoglycan

Answer 4

Gram positive cell

Question 5

What are the three general shapes of bacteria the chain and cluster

Answer 5

Coccus-circle
Bacilius- rod
Sprillium- spiral
stayphlo- cluster
strepto- chain

Question 6

Why is bacteria capable of growing after many years of inactivity

Answer 6

they can remain dormant because they have an endospore (outer coat)

Question 7

Compare binary fission and conjugation

Answer 7

Binary Fission- asexual (grows twice its size, splits into 2, 20 mins)
Conjugation- sexual (more variety, exchange DNA through pilis)

Question 8

How do prokaryotes evolve

Answer 8

sexual reproductions and mutations

Question 9

Why are some bacteria immune to antibiotics

Answer 9

see article

Question 10

Facultative bacteria require what type of condition to live

Answer 10

may or may not use oxygen

Question 11

contrast photoautotrophs, chemoautotrophs, and heterotrophs/sapertrophs

Answer 11

photoautotrophs make food from light and energy, chemoautotrophs eat inorganic compounds, and heterotrophs eat dead/decaying matter

Question 12

compare aerobes and anaerobic bacteria

Answer 12

both grow

Question 13

contrast aerobes and anaerobic bacteria

Answer 13

aerobes need oxygen to grow while anaerobic bacteria does not need oxygen to grow

What do you call a bacteria that needs sunlight and oxygen to grow

Answer 14

aerobic photoautotroph

Question 15

What are the requirements for bacteria that are a faculitative saprophytic heterotroph

Answer 15

can live with or without oxygen and eats dead or decaying matter

Answer 22

West Nile, Mursa

Question 23

What is the difference between gram positive and gram negative bacteria

Answer 23

gram positive has an extra protein coat (peptidoglycan)
