Virus
What is located inside the capsid?
Nucleic acids (DNA/RNA)
What does "Characteristics of Life" mean?
The characteristics needed for something to be alive.
What is the first level of organization
atom
What is the function of a macrophage?
consume bacteria, viruses, invaders/antigen.
What is the inflammation response? (think of a time you got a booboo, what happens?)
swelling, redness, heat, scab, WBC (macrophage) come in for attack
What are the two particles viruses always have?
Capsid (protein coat) and Nucleic acid core (DNA/RNA)
True or False: There only needs to be 5 out of 8 characteristics for something to be considered alive.
False, Needs all 8
what is the 5th level of organization
tissue
What is an antigen
invador
What is a vaccine and why are they important?
a shot that contains a weakened/dead virus that provides immunity for defense. (creates antibodies)
How are Viruses classified?
shape, size, host type, type of genetic material
What are the 8 Characteristics of life
Cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, adaptation
Put this in order from smallest to largest: organelle, tissue, atom, cell, biome
atom, organelle, cell, tissue, biome
what does the term "lock and key" mean?
"lock and key" means that a specific antibody fits to a specific antigen.
How is the lysogenic cycle different from the lytic
lysogenic cycle has a longer onset and becomes part of the new DNA
1. attach to host cell
2. genetic material enters the cell
3. host cell copies viral DNA
4. transcribed and translated
5. host cell lysis
Lytic Cycle
Is a sunflower alive? Why or why not?
Put this in order from largest to smallest
organ system, cell, atom, molecule, organism, tissue
organism, organ system, tissue, cell, molecule, atom
what are the 5 barriers of defense?
Skin, mucous membrane, saliva, tears and urine, stomach acid
Using the 8 characteristics of life, are bacteria alive? why/why not
yes, has all 8
How are viruses transmitted? (must have all 5)
airborne, contaminated food/water, infectious animals, sexual contact, contaminated blood
Is a virus alive? Why or why not?
by it's self, it is missing some characteristics (cellular organization, reproduction, metabolism, growth and development), ; attached to host cell it has all 8 characteristics.
What are the levels of organization from smallest to largest? (starting with atom and ending with biosphere)
atom, molecule, organelle, cell, tissue, organs, organ system, organism, population, community, ecosystem, biome, biosphere
What cells produce specific antibodies for the antigen?
B cells
What does the helper t cell do?
'teaches' b cells to make specific antibodies
