What direction do solutions always move across a semi-permeable membrane during diffusion?
a) Low concentration to high concentration
b) High concentration to low concentration
c) Inside the cell to outside the cell
d) Outside the cell to inside the cell
The movement of particles through proteins in the cell membrane against the normal direction of diffusion is called ___.
a) passive transport
b) active transport
c) osmosis
d) diffusion
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 outside of the cell.
b) stop moving across the membrane
c) continue to move across the membrane in both directions

a) passive transport
b) active transport
c) osmosis
d) diffusion
What materials does diffusion, osmosis, and facilitated diffusion move?

a) an organ system
b) an environmental stimulus
c) a biological adaptation
d) a feedback system
Some Galapagos finches have heavy, strong beaks, while others have small pointed beaks. Which best explains the differences in their beaks?
a) The climate is different for these birds
b) There are different predators where the birds live
c) There are different foods available where the birds live.
d) The beak allows them to attract a suitable mate
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) Simulation
b) Adaptation
c) Competition
d) Environmentalism
The finches that Darwin studied differed in the shape of their beaks. According to Darwin, the finches probably
a) all had a common ancestor.
b) had been created by design that way.
c) were descended from birds in Africa.
d) ate the same diet.
The different beaks Darwin observed in the finches were probably NOT caused by...
a) the finches' adaptations to the environment
b) asexual reproduction
c) variations in the genetic code
d) genetic mutations
Finches with__________ beaks are adapted to eat seeds off the ground
a) Long
b) Short
c) Medium
d) Pointed
Which part of the Beaks of Finches lab activity was changed in order to simulate the different conditions on various islands?
a) type of beak
b) size of beak
c) type of seeds present
d) size of stomach container
_____________ traveled to the Galapagos islands during his voyage on the HMS Beagle and found several variations of finches with uniquely shaped beaks.
a) Darwin
b) Mendel
c) Einstein
d) Coach Stewart
There are 13 species of Galapagos finches with 13 varieties of beaks. When a drought affected the Galapagos Islands in 1977, seeds became scarce. Some finch species survived while other finch populations decreased. Which is the most likely explanatio

b) Finches with smaller beaks were able to change their diet to eat soft fruits.
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.
Warblers and swallows have thin and pointed beaks. These types of beaks are useful for...
a) cracking open seeds
b) tearing and ripping meat
c) finding and eating insects
d) spearing fish

a) Both birds have the same offspring.
b) Both birds have the same type of nests.
c) Both birds eat the same types of food.
d) Both birds live in the highest point of a tree.
