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.
Answer:This type of plate is Convergent plate boundary.
Explanation:from this figure we can see that two plates meet together and one of this plates go under the other plate and this represent the convergent plate boundary.
The neurotransmitter is Dopamine.
The following combinations of neurotransmitters seem to be at play in
those who suffer from ADHD is Serotonin, dopamine, and norepinephrine. Neurotransmitters,
also known as chemical messengers, are endogenous chemicals that enable
neurotransmission. They transmit signals across a chemical synapse, such as a
neuromuscular junction.
