Immunity with 100% correct
answers 2025
When a B cell is activated by a T cell, the B cell proliferates into two types
of cells: ________ cells, which secrete antibodies, and memory cells, which
are involved in the secondary immune response - answer plasma


Interferons and interleukins are types of - answer cytokines


Identify the modes of action of complement proteins. - answer - They
dismantle viruses
- They puncture bacterial plasma membranes


Rank the steps that lead to the formation of plasma and memory cells in
the correct order. Start with the earliest on top. - answer - An antigen-
presenting macrophage activates a T cell
- The T cell contacts a B cell that has surface receptors that can bind the
type of foreign antigen the macrophage presents
- Once an activated T cell finds a B cell match, it releases cytokines that
stimulate the B cell to divide
- The B cell gives rise to two types of cells -- plasma and memory cells


What type of disease does interleukin-2 treat? - answer Kidney cancer
recurrence


What type of disease do colony-stimulating factors treat? - answer Boost
white blood cell levels in people with suppressed immune systems, such
as individuals with AIDS

cause disease from those that are harmless

humoral, cellular


Rank the different steps that occur during HIV infection in the correct
order. Start with the earliest on top. - answer - In macrophages and
helper T cells, the virus adheres with its surface protein, gp120, to two
coreceptors on the host cell surface, CD4 and CCR5
- Another glycoprotein, gp41, anchors gp120 molecules into the viral
envelope
- When the virus binds both coreceptors, virus and cell surface contort in a
way that enables viruses to enter the cell
- Once in the cell, reverse transcriptase copies the viral RNA into DNA
- The viral DNA then enters the nucleus and inserts into a chromosome,
and new viral particles are formed


The complement system triggers the release of histamine that ___________ -
answer dilates blood vessels, increasing fluid flow to the infected area


The viruses that causes AIDS is called ________ - answer HIV
