Textbook Question
Chapter 48, Problem 15TYU
EVOLUTION LINK The number of protonephridia in a planarian is related to the salinity of its environment. Planaria inhabiting slightly salty water develop fewer protonephridia than those inhabiting less salty water, but the number of protonephridia quickly increases when the concentration of salt in the environment is lower. How is this increase adaptive? Explain.

- The Amoeba cell exhibits specialized abilities that enable it to react to a stimulus by producing a response or a behavior. It can do this because it has adapted properties exhibited by simpler more primitive cells. These cellular properties include a) Separation of the fluid environments inside and outside the cell. b) Active transport of Na+ out of and K+ into the cell, c) diffusion of Na+ in to and K+ out of a cell in reaction to a stimulus, d) the stimulus interacting with a receptor site in a membrane embedded protein, e) All of these are true.arrow_forwardWhich of the following describes a mutualistic relationship between insects and multicellular plants?
