Question
Exercise 3B why was there little or no weight change for the model "eell" conta PO solution A? Po st B. This system is said to be at eaquilibrium. Explain what equilibrium means in te the movement of water across the plasma membra ne of a cell? 2) The model “cell" containing solution B gained weight. Therefore, the water moved the "cell". Explain why the water moved as it did in this model system. 3) Model "cells" C and D both lost weight. Therefore, the water moved "cell". Explain why the water moved as it did in these systems. the 4) A. "Cell" C lost more weight than "cell" D over the same amount of time (60 min) Therefore, "cell" C lost water at a slower or faster rate than "cell" D. (circle one) B. Explain the cause of the difference in the rate of water loss for "cell" C andExplanation / Answer
Answer:
1. (A) Solution A is isotonic.
An isotonic solution exists when an equal solute concentration is present inside and outside a cell. Compared to the things around it, an isotonic solution has an equal amount of dissolved solute in it – which in simple terms, it means that it is a solution that is of equal tension.
(B) Equilibrium is the state when there is a uniform distribution of solvent particles on each side of a membrane, and the rate of flow of the solvent molecules is same across the membrane.
