Dissection lab In the past 3 weeks we have been dissecting animals of all different sorts. We dissected a worm‚ crayfish‚ grasshopper‚ and a perch (fish). In my conclusion I will explain the diet‚ habitat‚ and how these relate to the structure of these animals. First I am going to be talking about the worm. The Earthworms have setae in groups around or under their body. The setae‚ paired in groups on each segment‚ can be moved in and out to grip the ground or the walls of a burrow. Worms travel

Woodward he reconstructed the fossils to produce an unlikely result (Dawson and Woodward 1913). If it were to be more critically scrutinised‚ they may have reached the more accurate conclusion that many contemporaries reached – that the skull and mandible belonged to two different species (Feder 1990). It may be argued that it was Dawson’s inexperience that was at fault‚ however‚ the same cannot be said about Woodward

Neandertals are often criticized in modern society‚ and were thought of to be less intelligent than humans‚ however it has been proven that Neandertals‚ were in fact very intelligent. The debate on whether Neandertals are considered a separates species from humans has been controversial in the anthropological world. Homo sapiens‚ or humans‚ first popped up around 500‚000 years ago‚ were found globally‚ and showed tendencies of modern human culture (04/19 lecture). Neandertal remains have been dated

unknown etiology which is asymptomatic in nature. When multiple‚ small nodular protuberances appear on the alveolar bone‚ they are called exostosis. When a bony protuberance occurs it is called a torus and when it occurs on the lingual surface of mandible opposite to mental foramen it is called torus mandibularis.These bony growths enlarge slowly usually above the mylohyoid line at the premolar and canine area and has a tendency for recurrence.1‚2Tori are usually removed when they interfere with speech

Defining the Insect’s mouthparts‚ its modification and its association in aiding pest control management Nina Arra DJ. Rivera Biology Student‚ Department of Biology‚ College of Science‚ Polytechnic University of the Philippines ABSTRACT Classifications of insect mouthparts are based on the manner insects feed on plants. Insect mouthparts are of two main types: chewing and piercing-sucking. Some insects have modifications of these two basic types. A study in the modifications of mouthparts
