potassium
B
glucose
C
sodium
D
water
2) The diffusion of water through a selectively permeable membrane, such as the plasma membrane
A
active transport
B
mitosis
C
cytokinesis
D
osmosis
3) Facilitated diffusion move substances across the membrane with the aid of:

Vesicles
B
Nothing
C
Membrane proteins
D
Cholesterol
4) Which substances may pass through a cell membrane by simple diffusion?
A
protein and fat
B
carbon dioxide and water
C
starch and protein
D
carbon dioxide and starch
5) What direction do solutions always move across a semi-permeable membrane during diffusion?
A
High concentration to low concentration
B
Low concentration to high concentration
C
Inside the cell to outside the cell
D
Outside the cell to inside the cell
6) The movement of particles through proteins in the cell membrane against the normal direction of diffusion is called ___.
A
active transport
B
osmosis
C
diffusion
D
passive transport
7) During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will ___.
A
move across the membrane to the inside of the cell
B
continue to move across the membrane in both directions
C
move across the membrane to the outside of the cell.
D
stop moving across the membrane

A
active transport
B
diffusion
C
osmosis
D
passive transport
9) What materials does diffusion, osmosis, and facilitated diffusion move?
A
diffusion and osmosis move water; facilitated diffusion- large and charge
B
diffusion-water, osmosis- carbon dioxide, facilitated diffusion-small and nonpolar
C
diffusion-oxygen/CO2; osmosis-water, facilitated- large and charge (glucose/ions)

an environmental stimulus
11) Some Galapagos finches have heavy, strong beaks, while others have small pointed beaks. Which best explains the differences in their beaks?
A
There are different predators where the birds live
B
The beak allows them to attract a suitable mate
C
There are different foods available where the birds live.
D
The climate is different for these birds
12) Charles Darwin observed the finches on the Galapagos island and noticed that each species was well suited to the life it led due to the size and shapes of its beaks. Beak shape and size in these finches is an example of —
A
Environmentalism

Adaptation
C
Competition
D
Simulation
13) The finches that Darwin studied differed in the shape of their beaks. According to Darwin, the finches probably

had been created by design that way.
B
were descended from birds in Africa.
C
ate the same diet.
D
all had a common ancestor.
14) The different beaks Darwin observed in the finches were probably NOT caused by...
A
asexual reproduction

Long
D
Pointed
16) Which part of the Beaks of Finches lab activity was changed in order to simulate the different conditions on various islands?
A
type of seeds present
B
size of stomach container

type of beak

size of beak

Finches with smaller beaks were able to change their diet to eat soft fruits.
B
Finches with less colorful beaks were able to easily hide from predators.
C
Finches with more colorful beaks had a greater chance to mate and produce offspring.
D
Finches with beaks that were able to eat the types of seeds that survived, were more likely able to survive and reproduce.

cracking open seeds
C
finding and eating insects
