| What are the four types of "diversities"? |
|
Definition
1.Biodiversity: biological diversity
2.Genetic Diversity
3.Species diversity
4.Ecosystem diversity: Species richness at level of gene contribution |
|
|
Term
| Species Richness and Species Evenness |
|
Definition
-Number of species
-how species are found (numerically) in an environment |
|
|
Term
| Where is Biodiversity highest? Lowest? |
|
Definition
| Highest in Tropics, lowest in Arctics |
|
|
Term
| What are examples of biodiversity hot spots? |
|
Definition
1.Area with many endemic species
2.Islands
3.Isolated areas (oases, mountaintops, etc.) |
|
|
Term
| What are two reasons why Biodiversity is important? |
|
Definition
1.All species provide function to an ecosystem
2.Removal causes depletion of ecosystem function |
|
|
Term
| List some results of removal. |
|
Definition
1.Nutrients aren’t cycled
2.Water is not cycled
3.Soil health declines
4.Erosion increases
5.Climate begins to vary |
|
|
Term
| What does a highly biodiversitized environment have over others? |
|
Definition
| It is easily adaptable. Much like a factory, it is less susceptible to stress |
|
|
Term
|
Definition
| 2 organisms share characteristics because of decent from a common ancestor |
|
|
Term
|
Definition
Characteristics that serve similar functions but are derived from different origins
i.e. spider legs and human legs |
|
|
Term
| Describe the function of PROTEINS. |
|
Definition
-Composed of Amino Acids
-Provides structure for cells, tissues, and organs
-Enzymes and hormones |
|
|
Term
| How is DNA used to make proteins? |
|
Definition
| DNA>>(transcription)>>RNA>>(translation)>>PROTEIN! |
|
|
Term
| Where does transcription take place? |
|
Definition
|
|
Term
| Where does translation take place? |
|
Definition
|
|
Term
|
Definition
| polypeptide chains composed of amino acids (proteins) |
|
|
Term
|
Definition
| single strand of RNA synthesized from a double stranded DNA |
|
|
Term
| What happens during translation? |
|
Definition
| Using mRNA, tRNA attaches amino acids, facilitated by a ribosome |
|
