How do the physical characteristics of 1-hump and 2-hump camels differ from each other?

One-hump camels, also known as dromedaries, have a single hump on their back, while two-hump camels, known as Bactrian camels, have two humps. The humps store fat, which provides energy for the camels in harsh desert environments. Additionally, dromedaries have longer legs and a sleeker body shape compared to Bactrian camels.
