How does binary fission work in bacteria

Answer 11

Split a parent cell into 2 daughter cells that get an exact copy of dna from parent

Question 12

What is the name for sexual reproduction in bacteria

Answer 12

Conjugation

Question 13

How does conjugation work in bacteria

Answer 13

Bacteria gets stuck to pili and exchange genetic information

Question 14

What is transformation in bacteria

Answer 14

Happens when a cell picks up loose DNA from its surroundings and uses it

Question 15

What is an endospore

Answer 15

A dormant phase during bad conditions that bacteria go in

Question 16

Why is an endospore important for bacteria

Answer 16

Very resistant structures form around the chromosomes to resist extreme environmental conditions

Question 17

What are the roles of bacteria

Answer 17

Decomposition, Pathogens, symbiosis roles, commercial uses

Question 18

How do bacteria act like decomposers

Answer 18

Recycles important elements in the carbon and nitrogen cycles

Question 19

How do bacteria act like pathogens

Answer 19

they cause disease in humans, crops and livestock. They can make toxins and cause illness

Question 20

How do bacteria have symbiosis roles

Answer 20

(With humans) Bacteria in large intestine make vitamin k and B12

Question 21

How do bacteria have commercial use

Answer 21

Used in commercials for environmental clean up, sewage treatment, cheese, yogurt production

Question 22

Do antibiotics work to stop bacteria

Answer 22

Yes

Question 23

How do antibiotics stop bacteria

Answer 23

Stops bacteria from growing by preventing growth and reproduction, stops them from building a cell wall or making DNA/RNA

Question 24

What is expenential growth

Answer 24

The growth rate of bacteria, they devide every 20 minutes

Question 25

What is antibiotic resistance

Answer 25

When antibiotics become less effective at defeating bacteria

Question 26

How does antibiotic resistance happen

Answer 26

Bacteria reproduce so quickly so genetic mutations happen, these mutations make antibiotics less effective

Question 27

What do we have to do to make antibiotics more effective when we have antibiotic resistance

Answer 27

Change target place and change molecular structure of antibiotic

Question 28

How do plasmids affect antibiotic resistance

Answer 28

Some plasmids have genes for antibiotic resistance
