Answer:
C: Take infected amphibians and assign them to two populations. Leave one population alone; inoculate the other with Jl. Measure the rate at which infection proceeds in both populations.
Explanation:
In scientific investigations, the best way to determine the effect of certain experimental factor on the population of study is to have a baseline for comparison. This is usually referred to as controlled experiment.
<em>In the case of the observation that chytrid infection in amphibians seems to be inhibited by Janthinobacterium lividum, the best way experimental design is to get a population of amphibians suffering from the disease, divide them into two groups and subject them to the same conditions except the introduction of Janthinobacterium lividum to the skin of one of the groups.</em>
<em>A suitable method can thereafter be employed to measure the rate at which infection proceeds in both population. If indeed, the bacterium has the capacity to inhibit the infection, the rate of infection in the group with the bacterium will be significantly less than that of the group without the bacterium. </em>
The correct option is C.

<h3 /><h3>What is urinalysis?</h3>
Urinalysis is a chemical, physical and microscopical examination carried out on a urine sample. This can be used to detect a wide range of disorders such as:
- urinary tract infections,
The dipstick method of urinalysis uses a stick that is made up of chemicals which are capable of detecting the following through a colour change:
- Ketones,
- sugar,
- proteins,
- acidity, and
- blood.
The presence of fruity odor in the urine sample signifies that there is excess ketone in the body due to ketoacidosis.
