How can scientists use a simulation to perform experiments

Simulation, in industry, science, and education, a research or teaching technique that reproduces actual events and processes under test conditions. ... The interaction of these phenomena create new situations, even new rules, which further evolve as the simulation proceeds.

A simulation is a way of imitating a process or change in the real world to predict what will happen or explain what did happen and why. Scientists use simulations to answer questions, see how complex systems work, test ideas, and make predictions.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
