Question

question 16 (1 point)
why did the childs cells struggle to move nutrients up and down the body in the cold?
o a water becomes more dense when frozen making it harder to transport.
o b water is a universal solvent that carries nutrients in blood.
o c adhesion pulls water into tissues and the cold makes it more difficult.
o d the colder temperature limits cohesion, preventing water from circulating.

question 17 (1 point)
if ice sank instead of floated, what would most likely happen to lakes in winter?
o a plants would no longer be able to pull water upward
o b lakes would stay liquid all winter
o c lakes would freeze solid, killing aquatic life
o d cohesion would stop, and water would not stick together

Explanation:

For Question 16: Water is a universal solvent that carries nutrients in blood. In cold conditions, the properties of water - related to its role as a nutrient - carrier are not directly affected by density changes (water actually expands and is less dense when frozen), adhesion is not the main factor here, and cohesion is not the limiting factor for nutrient - transport in this context.
For Question 17: Ice floating insulates the water below, preventing lakes from freezing solid. If ice sank, the entire lake would eventually freeze solid, which would be detrimental to aquatic life.

Answer:

Question 16: b. Water is a universal solvent that carries nutrients in blood.
Question 17: c. Lakes would freeze solid, killing aquatic life.
