Answer 25

Pro Eu

No Nucleus | Has Nucleus
Often unicellular | Often multicellular
DNA in nuclear region | DNA in nucleus
(No Organelles | (Many membrane
except ribosomes) | based organelles)
reproduce asexually | reproduce both
many anaerobic | Most aerobic

Question 26

What is a virus

Answer 26

microscopic organisms that has to infect hosts, like humans, plants or animals

Question 27

Why are viruses considered non-living

Answer 27

Unable to reproduce by themselves
Unable to move independently
Do not react to stimuli
Lack cell structures

Question 28

What are the main parts of a virus

Answer 28

Genetic material (DNA and RNA)
Protective Protein Coat (called a Capsid)

Question 29

What virus infects bacteria

Answer 29

Bacteriophages

Question 30

What are the names of the 2 virus reproduction cycles

Answer 30

Lysogenic, and Lytic

Question 31

What does the lysogenic cycle do (simple)

Answer 31

Virus injects DNA into host cells chromosomes and becomes inactive. Then when the virus DNA joins the host DNA it is now referred to as a provirus

Question 32

What does the Lytic cycle do (simple)

Answer 32

Virus injects DNA into host DNA. Then viral DNA hijacks the host and uses it to replicate new viruses

Question 33

What are the 5 steps of the Lytic cycle

Answer 33

1. Attaches to receptor
2. penetrates
3. Multiplies
4. Assembles
5. Lysis (releases and kills host)

Question 34

What are the 4 steps of Lysogenic cycle

Answer 34

1. Viral DNA combines with host DNA
2. Viral DNA replicates along with the hosts
3. Virus reactivated
4. Enters the Lytic cycle

Question 35

Why are viruses good

Answer 35

Some Viruses protect us and without them we would not be alive

Question 36

How do vaccines work

Answer 36

They have a weaken part of the virus and your body knows to look out for bad guys now

Question 37

What is s Bacteria’s favorite environment

Answer 37

Warm, dark, and moist

Question 38

What are the 3 main Phyla of Archaea

Answer 38

Anaerobic, Halophiles, Thermoacidophiles

Question 39

What are the 4 ways to classify bacteria

Answer 39

Cell shape, cell wall structure, motility, metabolism

Question 40

What are the 3 cell shapes for bacteria

Answer 40

Cocci (sphere), Bacilli (rod shaped), Spirochetes (spiral)

Question 41

What is bacteria cell wall made of

Answer 41

Peptidoglycan

Question 42

What are the 4 ways bacteria reproduce

Answer 42

Binary fission - parent cell divides to form 2 cells and happens quick so mutations
Conjugation - passes a copy of a plasmid to a nearby cell through a pilus
Transformation - pick up pieces of DNA from the environment or dead bacteria
Transduction - some receive new genetic material through viruses

Question 43

Where is Penicillin from and what does it do

Answer 43

It is from Fungi and is an antibiotic and doesn’t work on viruses

Question 44

What do helpful bacteria do

Answer 44

Natural recycling, Health and medicine, clean-up

Question 45

What is the problem with anti biotic overuse

Answer 45

Since bacteria reproduce so quickly, there is a high rate of mutation in the plasmid to create antibiotic-resistance. Since we keep overusing it it builds immunity faster.
