A)It is considered to be a type of passive transport.
B)It moves substances from higher to lower concentration.
C)It occurs due to random molecular motion.
D)It requires the energy of ATP.

D)To make the shell turn a pinkish color
E)To separate the egg shell from the rest of the egg

Answer 3

A

Question 4

In the molasses experiment, after 30 minutes, the molasses level in the stem of the thistle tube had gone up.

Question 5

In this lab exercise, potassium permanganate was used to illustrate the process of ________.

A)facilitated diffusion
B)active transport
C)pinocytosis
D)diffusion
E)filtration

Question 6

A 7% solution of glucose would be considered hypertonic to human cells.

Question 7

In the carrot experiment to demonstrate osmosis, we would expect the string around the carrot placed in salt water to be tighter than the one placed in tap water, because both the salt and the water diffuse into the carrot.

Question 8

Which of the following is NOT an active process by which substances cross the plasma membrane?

A)Pinocytosis
B)Filtration
C)Active transport
D)Phagocytosis
E)All of these are active processes.

Question 9

In the lab experiment on filtration, iodine potassium iodide (IKI)is used to test for the presence of glucose.

Question 10

In the filtration experiment, which substances passed through the filter paper because of their small molecular size?

A)Water, glucose, starch, and charcoal
B)Water, glucose, and starch
C)Water and glucose
D)Starch and charcoal
E)Water, starch, and charcoal

Question 11

Which of the following transport processes requires the energy of ATP to move substances across the plasma membrane?

A)Diffusion
B)Osmosis
C)Facilitated diffusion
D)Active transport
E)Filtration

Question 12

Which of the passive transport processes requires hydrostatic pressure to transport molecules across membranes in the body?

A)Osmosis
B)Filtration
C)Facilitated diffusion
D)Pinocytosis
E)Diffusion

Question 13

If a person were to hypothetically drink a very large volume of plain tap water, his/her cells would ________.

A)undergo rapid mitosis
B)crenate
C)not change
D)shrink
E)swell, and perhaps burst

Question 14

An example of filtration in the body is the movement of water and small solutes through the walls of capillaries.

Question 15

Passive transport processes, such as diffusion, are also called physiological processes.
