B) A non-living infectious particle that requires a host cell to replicate.
C) A complex cell with organelles and a nucleus.
D) An infectious particle that can reproduce without a host.

Answer 1

D) An infectious particle that can reproduce without a host.

Question 2

Are viruses alive?

Answer 2

Not truly alive so not a kingdom of its own

Question 3

Do viruses have a cell wall?

Answer 3

No and no cell membrane either

Question 4

Body=protein coat around……

Answer 4

dna/rna

Question 5

PT 2 VIRUS REPLICATION
Viruses make copies of themselves using a host cell’s materials and DNA. Which of the following describes the two primary methods by which viruses replicate?

A) Binary fission and budding
B) Conjugation and transformation
C) Lytic cycle and lysogenic cycle
D) Meiosis and mitosis

Answer 5

C) Lytic cycle and lysogenic cycle

Question 6

WHAT IS THE LYTIC CYCLE?

Answer 6

THE VIRUS IMMEDIATELY FORCES THE HOST CELL TO MAKE MORE VIRUSES

Question 7

WHAT ARE THE STEPS IN A LYSOGENIC CYCLE?

Answer 7

(a)The virus merges its DNA with the host
cells’ (b) The host divides many times (c) Lytic cycle takes over and
many viruses are made from many hosts

Question 21

PART 6 VIRAL DISEASES what are viral diseases

Answer 21

influenza (flu) ebola herpes hpv hika hiv covid 19

Question 22

What are HIV effects

Answer 22

HIV attacks and controls T cells and makes them unable to protect the body (this causes AIDS)
This causes people to die from diseases that would normally not kill a person (Example= pneumonia)
