What is an explanation for a question or a problem that can be experimentally tested? a. Conclusion b. Hypothesis c. Control d. Observation Scientific Method
Scientific Method
What is the independent variable in the data table? a. There is no independent variable b. Number of Tadpoles c. Amount of water d. p. H Scientific Method
The independent variable is what you change. It is also called the manipulated variable. Scientific Method
How is the relationship between distance and time different in Car #1 and Car #2? a. Car #1 has a direct relationship and Car #2 has an inverse. b. Car #1 has a linear relationship and Car #2 has an exponential. c. Both a and b d. Neither a nor b Scientific Method
Increasing graphs show direct relationships. Scientific Method
In the experiment, what type of variable is the amount of light? a. Independent variable c. Control b. Dependent variable d. Constant Scientific Method
Constant and Control are not the same. Constants are things kept the same for each condition. Controls are comparisons. Scientific Method
A student designed an experiment to determine what influences the rate of water loss from the leaves of plants. Does the experimental set-up below reflect a good experiment? a. Yes plants are easy to monitor. b. No, too many variables being tested. c. Not enough information to determine Scientific Method
A controlled experiment is one in which only one variable is allowed to change from one test to another. Scientific Method
What would a herd of wild horses would be considered? a. biosphere b. biome c. population d. organism Ecology
Herd is a group of the same organism in the same area. Ecology
What are animals that consume only plants? a. producers c. carnivores b. herbivores d. omnivores Ecology
Ecology
Which trophic level contains the most biomass? a. Tertiary consumer b. Secondary consumer c. Primary consumer d. producer Ecology
As you go up trophic levels, numbers of organisms, mass and energy from the sun decrease. Ecology
Which direction does energy flow? a. Tree to deer to cougar c. Bird to skunk to insects b. Sun to bear to cougar d. Rodent to bird to bear Ecology
Energy, food and nutrients follow the arrows into the mouths. Ecology
What is the role of a detritivore in an ecosystem? a. They are food for consumers. b. They return nutrients back to the soil. c. Through photosynthesis they can make their own food. d. They eat plants. Ecology
Detritivore = Decomposer Ecology
Which pond shows the most species biodiversity? a. Pond A c. Pond C b. Pond B d. Pond D Biodiversity & Populations
Species Biodiversity is the degree of variation of life forms within a given ecosystem, biome, or entire planet. Biodiversity is a measure of the health of ecosystems. Biodiversity & Populations
The dramatic rise in the rate of extinction of species is thought to be due to _. a. the reduction of the ozone layer b. the difference between the needs of the human population and available resources c. intentional introduction of foreign species into new environments d. acid rain Biodiversity & Populations
Rapid environmental changes typically cause mass extinctions. One estimate is that <1% of the species that have existed on Earth have become extinct. Biodiversity & Populations
What can be concluded from the graph? a. The deer population is at or below the carrying capacity of the environment. b. No limiting factors are working on the deer population. c. The deer is in exponential growth. d. The deer population is stable. Biodiversity & Populations
Average population stayed near the dotted line. Biodiversity & Populations
What type of relationship exists between the lynx and the hare? a. Mutualism b. Predator and Prey c. Parasitism d. There is no relationship Biodiversity & Populations
Lynx eats Hare so the populations are linked Biodiversity & Populations
An even distribution of ages among the population is a feature of ___. a. rapid population growth b. slow population growth c. Negative growth d. No growth Biodiversity & Populations
Biodiversity & Populations
What marcomolecule contains an organism’s genetic material? a. Proteins c. DNA b. Lipids d. carbohydrate Chemistry of Life
All living things have DNA. It is a molecules that provides instructions for making proteins. Chemistry of Life
What are the basic building blocks of proteins? a. Nucleic acids b. Peptide bonds c. Amino acids d. Fatty acids Chemistry of Life
Amino acids are the repeating units in protein polymers. Chemistry of Life
Which compound is considered an organic molecule? a. Salt b. Protons c. Water d. Nucleic acid Chemistry of Life
Chemistry of Life
The various enzymes in our bodies are _____. a. lipids b. carbohydrades c. Nucleic acids d. proteins Chemistry of Life
Enzymes are proteins that catalyze or speed up reactions. Chemistry of Life
Which biomolecule stores energy? a. lipids b. proteins c. carbohydrates d. Both a and c Chemistry of Life
Chemistry of Life
Which of the following do not have cell walls? a. animals c. all eukaryotes b. plants d. all prokaryotes Cell Structure
Cell wall is not the same and plasma membrane. The cell wall helps provide structure for a cell. Plants and Prokaryotes have a cell wall. Cell Structure
If a cell contains a nucleus, it must be a(n) a. Plant b. animal c. prokaryote d. eukaryote Cell Structure
Both plants and animals have a nucleus and other membrane bound organelles. Cell Structure
What other cell structure that is not found in all eukaryotic cells is likely to be found in a cell that contains the following organelle? a. ribosome b. mitochondria c. lysosomes d. central vacuole Cell Structure
Chloroplasts are needed for photosynthesis and are found in plant cells. Cell Structure
What is the purpose of ribosomes? a. To make DNA c. To transport materials throughout the cell b. To package materials d. To make proteins Cell Structure
ØRibosomes make proteins by arranging amino acids according to instructions from RNA. Ø Ribosomes are found in all cells. ØIn eukaryotes they float free in the cytoplasm and attach to the outside of the endoplasmic reticulum. Cell Structure
A plasma membrane is made up of a(n) _____. a. Lipid bilayer b. Enzyme bilayer c. Carbohydrate bilayer d. Protein layer Cell Structure
The plasma membrane has 2 layers of phosolipids that allow very small molecules to pass right through, but stops larger ones. Cell Structure
The nonliving factors of an ecosystem are called a. Population b. homeostasis c. Abiotic factors d. Biotic factors Hodge Podge
A = without; Bio =life Hodge Podge
Based on the following table, What time period will provide the most flowering plants? a. 3 -4 b. 5 -6 c. 7 -8 d. 9 -10 Hodge Podge
Although odd numbers do not appear in the table, after 8 days, the plants decrease. 7 -8 is the best option. Hodge Podge
