or
short term comepensatory changes
what process does adaptation describe
natural selection acting to adjust the frequency of fitness related genotypes
what are short term compensatory changes also known as
Phenotypic plasticity
what are the 3 physiological responses
adaptation
acclimitzation/acclimatation
acute response
What is adaptation
slow process over a long period of time rarely reversible
what is acclimitzation
more rapid physiological/biochemical changes
after exposure to new environmental conditions
what is an acute response
very short term change
what do animals do when presented with changes to conditions
homeostatis-maintenance of a constant internal environment
what is avoidance
spatial respone
get away from environmental problem
what is conformity
change interal state so it’s similar to the external environment
what is regulation
aim to maintain internal state irrespective of external environment
what do small soft bodied animals tend to be
they tend to be avoiders and conformers
what do medium sized animals tend to be
partial regulators or spatial avoiders
what do large sized animals tend to be
regulators in all environments
where does development of gametes take place in fucoids
In the receptacle
