Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).
The answer is; donation of a proton to water
Acids are proton donors. As viewed in the equation, the lactic acid partially dissociates in the water to form a conjugate base and hydronium ions. This is a property of an acid. The water acts as a base is donated a hydrogen ion be the lactic acid to form a conjugate acid H3O+.
Cocaine induces a sense of exhilaration by increasing the availability of dopamine and serotonin in synapses. Cocaine is among the powerful stimulants which increase the release of neurotransmitters such as nor-epinephrine, dopamine and serotonin, that affect CNS and PNS activity. Cocaine administration constricts blood vessels that are absorbing it, son snorting it is a slow way to deliver it to blood stream and eventually the brain.
