Term | Definition |
Describe in detail the difference between an open and a closed circulatory system. | An Open Circulatory System pumps blood into a hemocoel & A Closed Circulatory System pumps blood into vessels. |
Name 2 organisms that use an Open Circulatory System. | Lobsters, crabs, clams, insects, ect. |
Describe one difference between lungs and gills. | Gills filter water so they can take only the oxygen, while lungs just take in oxygen. |
Name group of organisms that use a tracheal system. | Insects. |
Describe 2 differences between vascular and non-vascular plants. | |
Identify the starting materials required for photosynthesis. | Sunlight/energy, water, and carbon dioxide. |
Identify the products of photosynthesis. | Oxygen and Glucose. |
What is the connection between the products of photosynthesis and the reactants required for cellular respiration. | The starting materials cellular respiration are the products of photosynthesis. |
Describe 2 factors that can limit the efficiency of photosynthesis. | Water and sunlight availability. |
Describe 2 functions for the glucose molecules plants create during photosynthesis. | Food and energy. |
Describe 2 functions for lipids in the human body. | Brain structures and cell membranes. |
Which type of organic molecule constitutes the backbone of DNA molecules? | Nucleic Acid. |
Define the process of decomposition. | Breakdown of dead organic materials. |
What happens to the organic products of decomposition (in other words, what type of organisms use those products and how do they use them)? | Plants use the carbon dioxide that is released for photosynthesis. |
Explain how changes in balance of the nitrogen cycle can have negative effects on the environment. | Nitrogen pollution into waterways can cause dead zones. |
A predator/prey relationship exist between 2 mammals in a relatively isolated environment. Describe the short term effect of an increase in reproductive rate of the predator. | Decrease in prey population. |
Scientist reintroduce grey wolves into a national part in the western United States. After 20 Years, the population of elk, a prey of the wolves, has increased, as has the wolf population.Give one possible explanation for this finding. | There are no longer any starvation events in the Elk population. |
Identify 2 differences between air pollution caused by greenhouse gases and air pollution caused by smog. | Greenhouse gases exist higher in the atmosphere and don't directly affect human health. |
Identify one negative effect of pollution caused by runoff from fertilizer use. | Algae blooms cause dead zones. |
What do nearly all scientist agree is the cause of the 1.4 degree increase in global temperatures over the past century. | Production of greenhouse gases due to human activities. |
Define the potential ecological problem ocean acidification(mention CO) | Excess CO dissolves in oceans causing a drop in pH. |
Describe 2 ways individuals can limit their contribution to greenhouse gas pollution. | Use public transportation and energy efficient light bulbs. |
Describe the competition that might occur between 2 garter snakes. | Size and coloration. |
What adaptation(s) might give one snake a survival and reproduction advantage over a competitor/ | Larger Size |
Define natural selection, and give one example of natural selection discussed in class. | Giraffes with longer necks have a survival advantage. |
