Which is false about osmosis and electrolyte balance in the body? when potassium enters cells, then water follows it. water travels from high to low concentration of the solute. if sodium leaves the inside of the cell, then water follows it?

water travels from high to low concentration of the solute

Electrolytes are known to be major components pf body fluid and these electrolytes enter the body through foods. Thus, major regulation of body fluid and electrolyte balance in the body is through the process of osmosis. However, osmosis can be defined as the movement of water through the semipermeable membrane from lower concentration of solute to higher concentration of solute.

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.
