occurs when birth rate and death rate are equal/stable
Endocrine Disruptors
Give this one a try later!
environmental disruptors of normal hormone function (reproductive
problems)
hydrophobic toxins
Give this one a try later!
fat soluble toxins, require carrier for movement, easily penetrate tissues
once transported. persistent.
, Factors that determine toxicity
Give this one a try later!
-length of exposure
-chemical concentration
-dosage
-target organism sensitivity
-route of exposure
Antibiotic resistance
Give this one a try later!
-certain strains of bacteria resistant to antibiotics
-occurs as a result of people not finishing full prescriptions of antibiotic
(evolution of survival)
-farm animals excrete antibiotics that make their way to surface water--
creates further resistance.
