Viruses Characteristics
3 ways to control a virus?
What is vaccine, interferon, and antibodies?
(T/F) Viruses are much smaller than cells and bacteria.
What is TRUE
The genetic code found in every cell
What is DNA?
This is where nucleic acid is stored within a bacteriaphage virus.
What is in its capsid?
Provide 2 reasons that would classify viruses as nonliving.
Not made of cells or organelles, Can’t reproduce on own, Don’t metabolize energy, Don’t perform cellular processes
This is the type of medicine that is a weakened version of the virus and most effective way in preventing the spread of a virus
What is a vaccine/vaccination?
the process of keeping the internal environment stable/balance/constant
What is HOMEOSTASIS?
What ways do viruses vary?
What is size, shape, and specificity?
Provide 2 reasons why viruses are considered living
Reproduce, Have nucleic acid, Adapt to surroundings, Have organization
Traits giving an organism an advantage in a certain environment.
What is ADAPTATIONS?
(T/F) A virus is not a bacteria, fungus, protist, plant or animal.
What is TRUE?
During the lysogentic cycle, the virus does this.
What is inserts viral DNA into cell & viral DNA is replicated.
Examples of Viruses
Influenza, colds, chicken pox, measles, polio, HIV, Covid-19
Responding to internal factors like hunger, thirst, pain
What is INTERNAL STIMULI
What are ways organisms reproduce?
What is ASEXUAL and SEXUAL?
A virus enters a cell, makes copies of itself and causes the cell to burst
What is lytic cycle?
(T/F) Viruses only target animals and humans.
A virus integrates its DNA into the DNA of the host cell. It may remain inactive for a period of time.
What is Lysogenic cycle?
The process of using raw materials for energy.
What is METABOLISM?
What are two biomolecules that all viruses have?
What is PROTEIN AND NUCLEIC ACID?
