|---|---|---|---|---|---|
| Archaebacteria | In this kingdom the organisms are unicellular and are more ancient than bacteria, but are closely related to Eukaryotes. They can live in extreme environments like hot spring.
🗑
|
||||
| Protista | This kingdom can be multicellular and unicellular. It is both heterotroph and autotroph and they are all Eukaryotes.
🗑
|
||||
| Natural Selection | Process that results in the adaptation of an organism to its environment by means of selectively reproducing changes in its genotype.
🗑
|
||||
| Stabilizing Selection | Most common form of natural selections in which organisms with organisms with extreme expressions of a trait are removed. Can be expressed on a graph.
🗑
|
||||
| Direction Selection | Shift of population toward an extreme version of a beneficial trait. Can be expressed on a graph.
🗑
|
||||
| Disruptive Selection | Process by which individuals with average traits are removed, creating two populations with extreme traits. Can be expressed on graph.
🗑
|
||||
| Evolution | The process through which species change over time.
🗑
|
||||
| Speciation | The formation of new and distinct species in the course of evolution.
🗑
|
||||
| Species | Groups of actually or potentially interbreeding populations, which are reproductively isolated from other such groups.
🗑
|
||||
| Endosymbiotic Theory | The term means to "cooperate inside", two small cells (Mitochondria and Chloroplast) were engulfed by a much larger cell, which became beneficial to the cells.
🗑
|
||||
| Gene Flow | The transfer of alleles or genes from one population to another.
🗑
|
||||
| Mutations | permanent change in a cell's DNA, ranging from changes in a single base pair to deletions of large sections of chromosomes.
🗑
|
||||
| Founder Effect | Occurs when a new colony is started by a few members of the original population.
🗑
|
||||
| Common Ancestor | The most recent ancestral form or species from which two different species evolved.
🗑
|
||||
| Adaptation | Process by which an animal or plant species becomes fitted to its environment; it is the result of natural selection's acting upon heritable variation.
🗑
|
||||
| Genetic Recombination | the process or act of exchange of genes between chromosomes, resulting in a different genetic combination.
🗑
|
||||
| Random Mating | mating between individuals of a species where the choice of partner is not influenced by the genotypes.
🗑
|
||||
| Taxonomy | A hierarchical system for classifying and identifying organism.
🗑
|
||||
| Plantae | This kingdom is a autotrophic eukaryote, have cell walls, and are not motile.
🗑
|
||||
| Fungi | In this kingdom the organisms are unicellular or Multicellular organisms. They absorb nutrients from other organisms; an example is a mushroom.
🗑
|
||||
| Reproductive Isolation | Occurs when members of a population no longer interbreed.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
