Explanation:
An electrolyte is a solution which is able to conduct electricity. An electrolyte conducts electricity because of the presence of ions which move around in the solution.
Ba(OH)2 and H2SO4 are composed of ions; these ions are the charge carriers in solution and are responsible for the conductivity of the solution and the glow of the bulb.
When Ba(OH)2 and H2SO4 are mixed, the following reaction occurs;
Ba(OH)2(aq) + H2SO4(aq) -------->BaSO4(s) + 2H2O(l)
The formation of the BaSO4(s) precipitate removes the ions that are responsible for the conductivity of the solution hence the light bulb of the conductivity apparatus dims and eventually fades completely.
Well, you just have to look for the one that does not have any positive/benefit.
1. is not the answer, since vaccines prevent countless people from disease and death.
2. is not the answer since animal abuse is not okay and the statement shows that science has become more efficient, therefore helping society become more efficient
3. is definitely not a positive effect that biotech has had on society. antibiotic-resistant bacteria endangers everyone. Therefore, this is the answer :)
4. is not the answer because helping people with diabetes be able to afford their medication is very helpful.
