Question

a) a researcher has observed that the concentration of solutes is different in the intracellular and extracellular regions of a particular type of tissue. pose a scientific question that would guide your investigation to explain this observation. (1 point)
b) the researcher has discovered that the membrane contains embedded proteins along with the phospholipid bilayer. how does this new information revise your initial question? (1 point)

Explanation:

a) A scientific question could be: "What mechanisms are responsible for the difference in solute concentration between the intracellular and extracellular regions of this tissue?" This question is focused on understanding the processes that lead to the observed concentration gradient.
b) With the new information about embedded proteins in the membrane, the initial question can be revised to: "How do the embedded proteins in the membrane contribute to the difference in solute concentration between the intracellular and extracellular regions of this tissue?" This revision takes into account the role of membrane proteins, which could be involved in active transport, facilitated diffusion, or other transport mechanisms.

Answer:

a) What mechanisms are responsible for the difference in solute concentration between the intracellular and extracellular regions of this tissue?
b) How do the embedded proteins in the membrane contribute to the difference in solute concentration between the intracellular and extracellular regions of this tissue?
