module 4 Flashcards
(19 cards)
what is in situ and ex situ
in situ = within natural habitat
ex situ = out natural habitat
what are consequences of in situ
cheaper
maintains genetic diversity
preserves interdependent relationships
name wildlife reservation techniques
controlled grazing
restrict human access
control poaching
reintroduction of species
cutting or removing invasive species
halting succession
what are some examples of ex situ conservation
botanical gardens
seed banks
captive breeding programmes
why can’t we release animals born in captivity to the wild
disease
behaviour
habitats
how does a pathogen cause harm
damage tissue directly
secrete toxins
what is natural active immunity
body itself has acted to produce antibodies
what is natural passive immunity
body is given antibodies
what is colostrum
the first milk a mother makes
what is artificial passive immunity
antibodies inserted into the bloodstream
what is artifical active immunity
vaccination, given dormant form of pathogen to stimulate production of antibodies
how can we deal with epidemic
mass vaccination
vaccine is changed regularly
what does mass vaccination offer
protection to those who don’t have immunity
(herd immunity)
how can we design drugs
computer programs
use molecular structures and tertiary structure
define personalised medicine
interweaving knowledge of drug actions with personal genetic material (pharmacogenomics)
define synthetic biology
develop populations of bacteria to produce drugs
define nanotechnology
strand of synthetic biology where non-natural particles are used for biological purposes
what do antiobiotics do
interfere with the metabolism of bacteria without interfering with the metabolism of human cells
selective toxicity
how do we deal with antibiotic resistence
minimise use of antibiotics
ensure every course is completed
good hygiene in hospitals + public spaces
