A drug treatment that is expected to have no pharmaceutical effect on humans/animals - answer ✔✔-
Placebo
positively charged ions - answer ✔✔-Cations
two or more forms of the same element that contain equal numbers of protons but different numbers
of neutrons in their nuclei. differ in relative atomic mass but not in chemical properties. - answer ✔✔-
Isotopes
is the movement of molecules across a membrane from a region of their lower concentration to a region
of their higher concentration—against the concentration gradient. Requires cellular energy. - answer
