Organisms, Environment, and Climate Factors
Agencies and Environment
Organisms are categorized into domains:
- Bacteria: Unicellular and prokaryotic, most are surrounded by a cell wall. Some perform photosynthesis, primarily absorbing their food from the environment.
- Archaea: Prokaryotic and unicellular, many can survive in extreme conditions. Their method of feeding is by absorption.
- Eukarya:
- Protista: Eukaryotic, unicellular, may perform photosynthesis, ingest, or absorb their food. They often move using cilia or flagella.
- Fungi: Generally absorb
Statistics Essentials: Stem Plots, Quartiles, Correlation
Stem Plots
To make a stem plot:
- Separate each observation into a stem (all but the final digit) and a leaf (the final digit). Stems may have as many digits as needed, but each leaf contains only a single digit.
- Write the stems in a vertical column with the smallest at the top, and draw a vertical line to the right of this column. Include all stems needed to span the data, even with no leaves.
- Write each leaf in the row to the right of its stem, in increasing order out from the stem.
Quartiles and Interquartile
