Answer 9

Check the diagram. The following should be included in the labelling and correctly placed :

1- Capsid ( protein coat)
2- Genetic material DNA
3- Shreth
3- Collar
5- Base plate
6- Tail fibre

Check the diagram. The following should be included in the labelling and correctly placed :

1- Capsid ( protein coat)
2- Genetic material RNA
3- Envelop
4- Envelop protein
5- Enzymes

Question 11

Name the 8 features of a virus

Answer 11

1- Non- living : Needs a host to survive
2- Much smaller than bacteria

3- Genetic material: DNA, RNA

4-Vary in shape: Bacteriophage, Human immunodeficiency virus

5- Capsid : Protein coat: Protection

6- Sometimes an outer envelop

7- No ribosomes or cytoplasm

8- They are infections, non living microbes that need a host to survive

Question 12

The 2C’s of virus and bacteria

Answer 12

Virus: Capsid
Bacteria: Capsule

Question 13

Difference between RNA and DNA

Answer 13

RNA: One strand
DNA: 2 strands

Question 14

Draw a diagram of a bacteria and label

Answer 14

Check the diagram. The following should be included in the labelling and correctly placed :

1- Flagellum
2- Pilus,Cellia
3- Nucleoid ( Containing circular DNA)
4- Ribosomes
5- Plasmid
6- Cytoplasm
7- Capsule
8-Cell membrane/plasma
9- Cell wall

Question 15

Name the 9 features of bacteria

Answer 15

1- Free living cells that can live inside or outside the body.

2- They can live and replicate on it’s own, no need for a host

3- They are found everywhere.

4- They contain 2 DNA materials : Plasmid, Nucleoid

5- Plasmid: Self defense

6- Circular Dna found in the Nucleoid providing bateria with advantages like antibiotic resistance

7- Flagellum, cellia - outer

8- Plasmid, Ribosomes, cytoplasm , nucleoid

9- Cell membrane, cell wall, capsule

Question 16

What happens if you are not consistant with your antibiotic

Answer 16

It becomes ineffective because the plasmid would’e built immunity against it.

Question 17

Compare and contrast viruses and bacteria

Answer 17

Similarities:
1- Genetic material DNA

Differences:

2- Virus: Protein coat
Bacteria : Cell wall

Question 18

Why don’t antibiotic work on viruses

Answer 18

Viruses have no cell membrane, no cell wall, no ribosomes ( antibiotics usually targets them and kills/destroys them) so they don’t synthesis protein, they do not respire since they are not living
