Question

which most likely uses biology and chemistry to develop new ways to control weeds? agronomist floral delivery driver butcher agricultural engineer

Explanation:

An agronomist studies plants and soil, which involves biology (plant life) and chemistry (soil composition, fertilizers, pesticides). They develop methods like herbicides (using chemistry) to control weeds that affect crop growth (biology - plant competition). A floral delivery driver just transports flowers. A butcher deals with meat (animal products post - slaughter, not focused on plant/weed control). An agricultural engineer focuses more on machinery and structures in agriculture, not as directly on the biological and chemical aspects of weed control as an agronomist.

Answer:

Agronomist
