Characterize hemolymph, as found in a spider
What will be an ideal response?
Hemolymph lacks cells to carry oxygen, but contains hemocyanin dissolved in the fluid hemolymph. Hemocyanin is composed of 48 protein subunits and each is larger than the subunits of hemoglobin, so this increases the amount of oxygen contained per unit of blood/hemolymph.
