Linnaeus introduced the rank-based system of nomenclature into biology‚ the highest rank was given the name "kingdom" and was followed by four other main or principal ranks.[1] Later two further main ranks were introduced‚ making the sequence kingdom‚ phylum or division‚ class‚ order‚ family‚ genus and species.[2] In the 1960s a rank was introduced above kingdom‚ namely domain (or empire)‚ so that kingdom is no longer the highest rank. Prefixes can be added so subkingdom and

Purpose: The purpose of doing this lab was to observe the regenerative patterns of planaria cells after a portion of their bodies was cut off. Background: 1. A blastema is a group of cells that forms at the site of a wound that eventually turns into the missing parts of a planaria. 2. Planaria fission occurs when a planaria is missing body parts. The organism attaches its tail-end to the ground and pulls itself forward using its head-end in order to tear itself into two parts. Then‚ each of these

Carl Linnæus Carl Linnaeus was a great scientist who made breakthroughs in botany‚ zoology‚ medicine and‚ most importantly‚ biology. He was one of the greatest scientists of his time. Even to this day‚ his system of naming organisms is used all over the world‚ and his theory in classification is still the most significant. Linnaeus was born on May the 23rd 1707 and he died on January the 10th 1778‚ at seventy years old. He lived in Sweden and studied in three different Swedish universities

Dissection Megan Williamson period: 3 4/29/13 Objectives: The purpose of this lab was to study and observe the organs in a crayfish and be able to name them. Introduction: Crayfish belong to the kingdom animilia‚ phylum arthropod and class crustaceans. The body is divided into three parts‚ the body‚ the head‚ thorax‚ and abdomen. The head and thorax are apart of a segment called cephalothoraxes‚ which is covered by the carapace made of chitin. The exoskeleton covers

Homo Sapiens Neanderthalensis Kingdom: Animalia Phylum: Chordata Class: Mamalia Order: Primates Family: Homildae Genus: Homo Brain Size: Neanderthal people had a brain volume of about 1200 to 1800 cubic centimeters‚ equal to and even larger than modern human brains. Neanderthal skull reconstructions provide further evidence that they were a separate species to modern humans. Distinctive Neanderthal skull features were established in early infancy. Physical features in skull development

Abstract Planaria belong to the class Turbella of the phylum Platyhelminthes. This paper depicts the behavioral reaction of Planarians to a variety of settings and compounds to better understand this particular Platyhelminthes. With a plastic syringe‚ it is possible to extract a sample of planaria‚ place into a Petri dish with enough freshwater and observe under a laboratory provided microscope. While on the microscope platform‚ expose your sample to light and darkness to notice the patterns of

Size: Architeuthidae can grow up to 60 feet in total length‚ and weigh between 1000 lbs and a tone. The Genus Architeuthidae are the largest known cephalopods‚ the largest known mollusks and the largest invertebrates ever known to exist in the ocean. Habitat: A giant squid lives between 200 and 1000 meters in depth‚ close to the bottom of the sea‚ around large underground canyons. They must live in deep water because the blood of squids does not carry oxygen very well at higher temperatures. If

Starfish or sea stars are marine invertebrates belonging to the phylum Echinodermata; class Asteroidea. Crown of Thorns Starfish (Acanthaster planci) are found on coral reefs in the tropics ranging from the Red Sea‚ the Indian and Pacific Oceans‚ and all the way to the Pacific coast of Panama. It plays a major role in the destruction of fast growing coral species. Scientists believe that this starfish has lived on the reefs for tens of thousands of years and when the populations of this echinoderm
