Answer: The most appropriate subject for a student to conduct an experiment on mosquito repellent would be: b) Biology.
Step-by-step explanation:
Biology is the study of living organisms, including insects like mosquitoes. Conducting an experiment on mosquito repellent falls under the realm of biology because it involves understanding the behavior, physiology, and interactions of mosquitoes and the effects of repellents on them.
In this experiment, the student could explore different types of mosquito repellents and test their effectiveness. They could set up controlled experiments to compare the repellency of various substances or products on mosquitoes. For example, they could design experiments to investigate the effectiveness of natural repellents like citronella oil or chemical repellents like DEET. They may observe and record factors such as the duration of repellency, the number of mosquitoes attracted, or the percentage of mosquitoes repelled by each type of repellent.
By conducting experiments in a controlled environment and collecting data, the student can gain insights into the effectiveness of different mosquito repellents. This knowledge can be valuable for personal use, public health, or even for developing new repellent products.
In summary, the subject that best aligns with the student's interest in running an experiment on mosquito repellent is biology. This subject allows for an understanding of mosquito behavior, the effects of repellents, and the design and execution of experiments to test and evaluate different repellent products.
