The sodium-glucose is a transmembrane protein and it occurs on the apical membrane epithelial cells of the small intestines. Sodium and glucose bind to this protein and are simultaneously moved into the epithelial cells using a sodium electrochemical gradient as its source of energy, and therefore this is a type of transport.

correct answer is symporter and  active

Explanation:

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.

they are known to reach a speed of 21 miles per hour
