A. Sedimentary rocks are made of layers of sediment, dirt, silt, etc., that are deposited down over time and cemented by minerals.
B. Igneous rocks are formed from the cooling of magma.
C. Metamorphic rocks are formed when other rocks are subjected to intense heat and pressure.

1. This type of rock is most likely to contain the fossil remains of ancient organisms: (A) sedimentary (B) igneous (C) metamorphic (D) all of the above


A. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration, without using energy.
B. Osmosis is the diffusion of water across a membrane.
C. Active transport uses energy to move molecule from an area of low concentration to an area of high concentration.
D. Facilitated Diffusion is when an opening in a cell allows materials to diffuse more quickly.

2. Nerve cells maintain a high concentration of Na+ ions outside the cell they do this through: (A) diffusion (B) osmosis (C) active transport (D) facilitated diffusion
3. When the nerve cells send a message for muscle cells to contract, a chemical message attaches to a receptor on the muscle cell membrane, and a channel is opened by the receptor allowing the Na+ ions to enter the cell through: (A) diffusion (B) osmosis (C) active transport (D) facilitated diffusion
4. When people breathe in oxygen and breathe out carbon dioxide, these gases are exchanged across the cell membrane automatically, without the cell doing anything, through: (A) diffusion (B) osmosis (C) active transport (D) facilitated diffusion
5. If a cell has a higher concentration of salt outside the cell than inside, then the water will: (A) move into the cell and the cell will shrink (B) move out of the cell and the cell will shrink (C) move into the cell and the cell will swell (D) move out of the cell and the cell will swell


A. Producers are organisms that make their own food, as a plant would.
B. Consumers are organisms that eat food made from other sources, as an animal would.
C. Decomposers are organism that break down dead organisms and return their nutrients to the environment, as certain bacteria do when they cause decay.

6. These first creatures on the planet probably lived off of molecules released from volcanic activity; they were: (A) producers (B) consumers (C) decomposers (D) both producers and consumers
7. These creatures are responsible for recycling nutrients in the environment and returning them to the soil: (A) producers (B) consumers (C) decomposers (D) both consumers and decomposers

9. According to the diagram above, in order to always have the maximum number of chicks survive, another adaptation the Blue-Footed Booby has developed is: (A) the larger chick pushes the smaller one out of the nest only when food is scarce (B) the larger chick always pushes the smaller one out of the nest (C) the weaker sibling crawls back into the nest only when food is scarce (D) the weaker sibling crawls back into the nest regardless of food supply


The five steps of Darwin's theory of evolution by means of natural selection.
A. There is variation in every population.
B. Organisms must compete for limited resources.
C. Organisms have more offspring than can survive.
D. Natural Selection: organisms with the most beneficial traits are more likely to survive and reproduce
E. Organisms pass traits on to their offspring.

10. The use of antibiotics is a very effective way of destroying pathogenic bacteria (disease causing), but sometimes people do not finish all of their pills. This can result in: (A) fewer bacteria (B) more bacteria (C) bacteria sensitive to the antibiotics (D) bacteria resistant to the antibiotics
11. This step can result in an increase in the population if there is an abundance of food available: (A) there is variation in every population (B) organisms must compete for limited resources (C) organisms have more offspring than can survive (D) organisms with the most beneficial traits are more likely to survive and reproduce
