Draw a Euglena and label the nucleus, chloroplasts and flagella. What is the purpose of the flagella?
Flagella is used for movement
The cell membrane lets some molecules in and keeps others out. Because of this it is called a semipermeable membrane.
If the dark squares are salt particles and the light circles are water molecules, what will happen in the above diagram?
What is this process called? If the cell is semipermeable the water will move into the cell causing the cell to expand. This
is the process of diffusion and the solution is said to be hypotonic.
Draw a picture of phagocytosis occurring.
Endocytosis, exocytosis, phagocytosis and pinocytosis are all types of ______Active transport, which requires energy.
What are channel proteins? Proteins embedded in the cell membrane that allows charged or large molecules through
membrane
What is bioaccumulation? Biomagnification when the concentration of a substance, such as DDT or other pesticides, in an
organism exceeds the background concentration of the substance in its diet. Usually passed through food chain and can
result in death.
Give an example of bioaccumulation: grasshoppers eating crops sprayed by pesticides and passing it the the birds eating
them
Why can there only be three or four trophic levels? As you move up the food pyramid that percent of energy gets less and
less. Therefore, you would not be able to survive past the fourth trophic level.
Draw a food web containing grasshoppers, rabbits, deer, grass, hawks, humans and potatoes.
Grasshopper
Grass
rabbit
Potatoes
Deer
Hawk
Human
In the food web above identify the organisms that fill the following niches:
Producer : Potatoe, grass
Primary consumer grasshopper, rabbit, Deer
Secondary consumer Hawk and Human

USING SCIENCE SKILLS
A student put together the experimental setup shown below. The selectively permeable membrane is permeable to both
types of solute molecules shown.
1. Interpreting Graphics Describe the experimental setup shown in Figure 7–4. Do you expect the distribution of the
solutes on each side of the membrane to change over time?The molecules will evenly distribute between the substances
until equal on both sides.
2. Predicting Describe the movement of the C molecules on side A of the apparatus shown in Figure 7–4. What will happen
to these molecules over time?
The C molecules will move to the right, so From side A to side B.
3. Predicting Look at Figure 7–4. Describe the movement of the D molecules on side A. What will happen to these
molecules over time?
The D molecules from side B will move to side A until evenly distributed.
4. Predicting What will the apparatus shown in Figure 7–4 look like when equilibrium is reached?
Once at equilibrium molecules will still move, but they will move from one side to the other at an equal rate.
5. Predicting Once equilibrium is reached in the apparatus shown in Figure 7–4, will the molecules continue to move?
Explain your answer. Yes but at the same rate.
Figure 7–5
6. Interpreting Graphics Which drawing in Figure 7–5 contains a structure that carries out photosynthesis? What is this
structure labeled in the diagram?
Drawing II does photosynthesis the structure labeled N (chloroplast)/
7. Comparing and Contrasting Look at Figure 7–5. Which structure in drawing I corresponds to structure M in drawing II?
What is the name of this structure? G which is the golgi apparatus
8. Comparing and Contrasting Which structure in drawing I of Figure 7–5 corresponds to structure L in drawing II? What
is the name of this structure? I cell membrane
9. Interpreting Graphics Which organelle is labeled K in Figure 7–5? What is the function of this organelle?
Nucleus control center of the cell.
Interpreting Graphics Do the drawings in Figure 7–5 represent prokaryotes or eukaryotes? How do you know?
Eukaryotes because they have a nucleus and membrane bound organelles.

11. Applying Concepts Charles Darwin would say that sharks like the one in Figure 15-4 exhibit fitness. Explain what that
means, and discuss two specific adaptations as part of your explanation.
Fitness is an adaptation that an organism possesses that gives it an advantage over another animal. For sharks their large
number of teeth makes them a fierce predator to help them survive. Cartilage could be seen as a benefit due to the less
likely of breaking.
12. Applying Concepts Evidence indicates that dolphins evolved from ancestors that walked on land. How can the concept of
natural selection be used to explain the evolution of the present-day dolphin body?
Coevolution- two different animals evolve to look similar to each other due to the environments they live in are similar.
13. Comparing and Contrasting Sharks and dolphins, which belong to different vertebrate groups, are not closely related.
How can Darwin’s ideas about evolution help explain such a similar appearance? They look similar and live in same
environment. Survival of the fittest.
14. Inferring If you wanted to find out whether sharks and dolphins share homologous structures, what structures would you
examine? Explain.
Their bone structures. Not their functions.
15. Predicting Suppose a dolphin population becomes trapped in a harbor that is growing smaller and more shallow because
of climate changes. Is it likely that the dolphins would evolve into a land-dwelling species in a few thousand years?
Explain your answer.
Which of the following organisms are most closely related? (there are two pairs) The genus names are the same
Common name
bobcat
Mountain lion
Tiger
Domestic cat
African lion
Scientific name
Lynx rufus
Felis concolor
Panthera tigris
Felis silvestris
