Answer:
The correct answer is 7.5 ml
Explanation:
The medicine contains 100 mg in 5 ml, that means that the concentration of the active ingredient is 100 mg/5 ml= 20 mg/ml
If we divide a concentration (in mg/ml) into a mass (in mg) we obtaine a volume (in mL). Thus, in order to calculate the mililiters of medicine which contain 150 mg of the active, we have to only divide mass (150 mg) into the concentration of active ingredient as follows:
mL = 
= 7.5 mL
The correct answer is: first level.

interleukin-2 (IL-2) is an interleukin, a type of cytokine signaling molecule in the immune system. It is a 15.5–16 kDa protein[5] that regulates the activities of white blood cells (leukocytes, often lymphocytes) that are responsible for immunity. IL-2 is part of the body's natural response to microbial infection, and in discriminating between foreign ("non-self") and "self". IL-2 mediates its effects by binding to IL-2 receptors, which are expressed by lymphocytes. The major sources of IL-2 are activated CD4+ T cells and activated CD8+ T cells
