Explanation: Toxicology is a branch of science that studies that adverse effects that occurs in living organisms when exposed to chemicals and physical agents.
Toxicology deals with risk assessment.
In toxicology, observation and reporting of the symptoms, mechanism of action, detection and treatment of toxic substances when exposed to living organisms especially humans are carried out.
The knowledge of toxicology aids in the advancement of environmental health.
This is a study that give details or accounts of events that occur after an exposure of organisms to certain doses or chemicals substances after a period of time, based on the extent of response of the organisms. The main objective is to determine the extent of effects(negative , rarely negative ) of the exposed chemicals, and the effects of levels of dosages on the organism. Thus it is a measure of how each level of exposure of to certain drugs or chemicals affects organism, through their responses after the exposure.
The effects and levels of exposure is usually represented with Dose-response Curve. This is a graphical representation of the potency of the exposed chemical substance e,g drug, and the effects on the functions of body systems of the organism.
The analysis from this is incorporated in public policy by the government, for safety of citizens.
Convection is the process of warm fluids rising and cooler fluids sinking. Inside the Earth, convection is powered by heat mostly from the core. The slow circulation of rock in the mantle moves the tectonic plates at the surface.
In terms of the giraffeexample, Darwin's theory of evolution through natural selection wouldsuggest that a giraffewas born with a longer neck by random chance. ... Having access to more food allowed the giraffe to live longer and reproduce more, ultimately leading to more long-neck giraffes.
Its b because Ocean acidification is occurring because excess carbon dioxide (CO2) in the atmosphere is being absorbed at the surface of the ocean at an increasing rate. This excess CO2 results in more hydrogen ions, which increases the acidity of the ocean.
