In a research there are two variables independent and dependent variable. independent variable is defined as the variable which is controlled and changed in a scientific experiment and evaluate the effects on the dependent variable while the variable which are tested and measured in experiment are called dependent variable.
When antibiotic is sprayed at one side of the petri dish, the bacterial growth on that side will eventually decrease in comparison to other side.
So, the independent variable in this experiment will be antibiotic because it is used to understand the growth of bacteria by decreasing their numbers and the dependent variable in this experiment will be bacteria as they vary according to the change in independent variable that is antibiotic.
Waste management would be the most difficult to reproduce once it runs out. Thus, option "C" is the answer.
<h3>What is waste management?</h3>
Waste management~ includes the activities and actions required to manage waste from its inception to its final disposal. This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process.
For example, Incineration is the process of burning of solid wastes. It is one of the processes of solid waste management. In this process, combustion of organic and inorganic wastes takes place that leads to the formation of ash, heat and flue gases. Ash is composed of inorganic constituents.
The heat generated during this process can be used to generate electricity. The process is carried out by Incinerators. Incinerators does not completely replace landfilling but it reduces the volume of disposal of wastes.
Thus, option "C" is the answer.
