Certain drugs will cause the pupils to dilate while other drugs cause constriction of the pupils. Certain drugs cause constriction of the pupils, such as alcohol. Other drugs, such as psychedelics, cause pupil dilation.Another term for the constriction of the pupil is miosis.Substances that cause miosis are described as miotic. The pupil opens wide when dark and small when light.est Answer: When bright light is shone on the eye, it will automatically constrict. This is the pupillary reflex, which is an important test of brainstem function. Furthermore, the pupil will dilate if a person sees an object of interest Looking at a personâs eyes is one of the first telltale signs of drug use.
a mole is the amount of pure substance containing the same number of chemical units as there are atoms in exactly 12 grams of carbon 12 i e 6 023 x 10 23 this involves the acceptance of two dictates the scale of atomic masses and the magnitude of the gram mole is the amount of pure substance containing the same number of chemical units as there are atoms in exactly 12 grams of carbon 12 i e 6 023 x 10 23 this involves the acceptance of two dictates the scale of atomic masses and the magnitude of the gram
As of 2011, the mole is defined by BIPM to be the amount of substance of a system which contains the same number of elementary entities (e.g. atoms, molecules, ions, electrons) as atoms in 0.012 kilograms of carbon-12 (12 C), the isotope of carbon with relative atomic mass 12.he mole may also be used to express the number of atoms, ions, or other elementary entities in a given sample of any substance. The concentration of a solution is commonly expressed by its molarity, defined as the number of moles of the dissolved substance per litre of solution.
