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

The classification of animals The Classification of animals : Animal Kingdom can be split up into main groups‚ vertebrates (with a backbone) and invertebrates (without a backbone). When you think of an animal‚ you usually think of something like a cat‚ a dog‚ a mouse‚ or a tiger. All told‚ around 800‚000 species have been identified in the Animal Kingdom -- most of them in the Arthropod phylum. In fact‚ some scientists believe that if we were to identify all species in the tropical rain forests

1. Anatomi dan Fisiologi Sistem Pencernaan Sistem pencernaan adalah sistem organ yang menerima makanan‚ mencerna‚ dan mengeluarkan sisa makanan dari proses pencernaan tersebut. Fungsi utama sistem pencernaan ini adalah untuk mengabsorpsi makanan‚ menyediakan zat nutrien yang sudah dicerna secara kompleks menjadi molekul sederhana‚ untuk di distribusikan ke dalam sel melalui sirkulasi dengan unsur-unsur (air‚ elektrolit‚ dan zat gizi) dan menyekresi sisa makanan. Sistem pencernaan manusia diawali

32.2.2 Segmentation allowed for redundant systems and improved locomotion Hox genes cause segmentation development 2 advantage of Hox genes Highly segmented animals‚ usually have nearly complete set of organs in theirs each segment of body. This result to less damage in their body‚ since other segment duplicate the damage segment functions Locomotion is more efficient‚ since partitions isolate the segment can contract and expand autonomously. 32.3.

James Sutton Excelsior Student Cynthia Jackson THE KINGDOMS OF LIFE Introduction: On our planet earth we have what are called kingdoms‚ 5 to be exact‚ consisting of a very diverse group of living things. Using these five kingdoms we classify our species and organize information on what we are and what resides with us. When we place every living creature into one of the five kingdoms it better helps us understand the world around us and it ’s habitants. The five kingdoms include:

Biology: Unit 1: Diversity Of Life Fungi Fungi: are multi-cellular heterotrophs that use external digestion‚ and often grow out of sight‚ underground → fungi have nothing in common with plants other then the fact that they are stationary‚ and grow in the ground. They are not photosynthetic‚ and they do not produce their own food. Characteristics/ Cell Structure: * Mesh like bodies‚ composed of branching networks of filaments called mycelium * Mycelium: a branched mass of hyphae
