Early Beginnings In the beginning of time humans believed that illness and disease was caused by super natural forces. Tribal doctors performed ceremonies to rid their patents of evil spirits. One of the ceremonies was trephining‚ trephining is where the doctor would remove a part of the brain with a primitive tool. They also used herbs and plants as medicines. Digitalis comes from the foxglove plant‚ it is used to strengthen and slow the heart rate. It was originally given where the patient

The story of the phylogentic tree of the animal phyla Animals never just started out as being classified among 9 different phyla. It started off with a single group known as the Ancestral colonial protists or Ancestral stock. From this stock‚ multicellular organisms developed. These multicellular organisms then later branched off into two separate directions. One branch turned into organisms which were asymmetrical‚ with no true tissue layers and no gut although it has two cell layers – the

Cladograms are a way for us to observe and analyze characteristics and evolutionary change between two phylums. Starting out with a character matrix allows us to determine synapomorphies and apomorphies between theses two group‚ allowing us to construct the cladogram (Reece). My cladogram consisted of various phylums from the Animal Kingdom. The outgroup for my cladogram was the Choanoflagellates due to the fact that “they are the closest‚ living‚ unicellular relatives of animals” (Leadbeater).

Raudah P. Mangbisa Grade VIII-Nilo VIRUS A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms‚ from animals and plants to bacteria and archaea. Characteristics: Like living organisms‚ viruses contain nucleic acids and proteins. Inside living cells‚ viruses can reproduce‚ but not by the process of mitosis like most living cells. Viruses lack some characteristics of living organisms. Outside of living cells‚ viruses are

The CELL THEORY‚ or cell doctrine‚ states that all organisms are composed of similar units of organization‚ called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859)‚ Mendel’s laws of inheritance (1865)‚ and the establishment of comparative biochemistry (1940). Ultrastructural research and modern molecular biology have

that can be seen as a white spot where the planarian was bisected (4). The planarian then regenerate a head from the cut of tail portion or a tail from the cut portion (4). It then takes about two weeks for the planarian to fully regenerate (4). A flatworm once survived being cut into 279 pieces and grew new bodies for every single one (el-Showk 1). Planaria do not have anatomical marks on their bodies‚ therefore it is harder to track their regeneration (Levin
