Dichotomous means divided into two parts which is why dichotomous keys always give two choices in each step. 
Example:
This dichotomous key is identifying whether or not the picture is a plant or animal. After looking at the picture, we can agree that it doesn’t have a woody trunk or a soft stem. But we can agree that it lives on land based off of the tree it is sitting on. We can also agree that it has feathers and not hair which brings us down to a bird. ]]> 2017-02-02 12:19:16 UTC https://padlet.com/paula_riley2/8hfwvbbpto77/wish/151105372 Group 5 period 1 nicholas ,jared ,Avery https://padlet.com/paula_riley2/8hfwvbbpto77/wish/151105529
As the name indicates ,deals with describing and naming organisms with systematics  deals with grouping and arranging the described taxa into a hierarchical classification . 

Benefits of Biology classification 

  • It makes the study of living organisms convenient.
  • It helps in the specific identifications of any given organism.
  • The study of a few representatives from each distinct group helps us to integrate the idea of life as a whole.
  • It reveals the relationships among various groups of organisms.
  • It provides information about plants and animals, which occur in specific geographical regions.
  • It indicates the evolutionary

Biologists used taxonomy to organize every animal by making groups and as you progress them farther you get more and more specific thus every animal can fit.]]> 2017-02-02 12:20:58 UTC https://padlet.com/paula_riley2/8hfwvbbpto77/wish/151105618 Group 7, Period 1 - Ryan Murphy, Glenn Santoro https://padlet.com/paula_riley2/8hfwvbbpto77/wish/151105633 'Taxon' is a category into which related organisms are placed. There is a hierarchy of groups from broadest to most specific. Some names for the classification groups would be Domain, Kingdom, Phylum, Class, Order, Family, and Genus.
'Domain' would be the broadest while 'Species' would be the most specific.]]> 2017-02-02 12:21:05 UTC https://padlet.com/paula_riley2/8hfwvbbpto77/wish/151105633 Group 2, Period 1 https://padlet.com/paula_riley2/8hfwvbbpto77/wish/151105840 Terryana, Gonzalo, Jordan, & Jenna.

Classification of many species, old and new, continues to be hotly disputed as scientists find new information or interpret facts in new ways. Arguments are fierce and species do change names, but only after a wealth of information has been gathered to support such a big step. One of the new reasons why species are being re-evaluated is because of DNA analysis. Basic genetic analysis information can change our ideas of how closely two species are related and so their classification can change. Now, DNA technology has allowed scientists to re-examine the relationships between organisms to refine the classification system.

(Using the common names of certain organisms) a mushroom can be placed in the kingdom Fungi visually. A cheetah is easily recognized to belong to the kingdom Animalia. Plants, Animals, Fungi, Eubacteria, and Archaebacteria. All but two of these kingdoms are easily recognizable to the average person. ]]> 2017-02-02 12:23:47 UTC https://padlet.com/paula_riley2/8hfwvbbpto77/wish/151106032 group 4. https://padlet.com/paula_riley2/8hfwvbbpto77/wish/151107018 laquantae , laquintae , Lidianna
One Species. Wolves and dogs belong to the same genus (Canis), although they are different species (Canis lupus for the wolf and Canis domesticus for the dog). DNA evidence has shown that domestic dogs trace their ancestry to wolves, although some breeds are many more generations removed than others.
