Question
Water moves via osmosis a) throughout the cytoplasm b) from an area with concentration concentration of water to one of lower concentration concentration of water to one of higher concentration a high concentration of other solutes to a lower one d) from with a high an area with a low The principal force driving movement in diffusion is the a) temperature b) particle size c) concentration gradient d) membrane surface area What problem is faced by organisms that live in fresh water? a) Their bodies tend to take in too much water b) They have no way of controlling their tonicity. c) Only salt water poses problems for animals that live in it. d) Their bodies tend to lose too much water to their environment Short Answers: cuss why the following affect the rate of diffusion: molecular size, temperature, solution density, and the distance that must be traveled Molecular size: Temperature Solution Density Distance: Q: Why does water move through a membrane? Wthe rhla m ered n medcine, lsine andI cated Ringer's solution,are isotonic. Why is this important 10Explanation / Answer
1) The correct option is c. from an area with a high concentration of water to one of lower concentration.
Osmosis is a process as diffusion, which involves water molecules. Water molecules move from areas of high water concentration to areas of low water concentration with the help of a selectively permeable membrane.
2) The correct option is c. Concentration gradient.
Molecules diffuse from areas of high concentration to areas of low concentration down a concentration gradient. During the process of diffusion molecules move down the concentration gradient.
3) The correct option is a. Their bodies tend to take in too much water.
Their bodies have well developed systems, which regulate the osmotic balance, or else they would all die. Water has a tendency to move from an area of lower to area of higher concentration. As fresh water is hypotonic to the body of organisms living in it, so, their bodies do not lose water to the surroundings.
