  • Echinoderm Connective Tissue

    Analysis of “Energy Expenditure Associated With Softening and Stiffening of Echinoderm Connective Tissue.” Echinoderms have a distinguishing feature that appears to be supernatural. They have the ability to rapidly adjust the connective tissue in their body wall from a stiff state to a tensile state within seconds. This seemingly heroic characteristic is called mutable connective tissue and it supposedly functions without much energy loss compared to muscle-mediated systems. Tatsuo Motokawa, Eriko

    Eric Ha Biology D 5/11/16 Comparison of Circulatory System between Human and Echinoderm I am going to show the similarities and differences of circulatory system of human and echinoderm. To begin with, I am going to write about the circulatory system of human. There are two types of circulation in circulatory system. First of all, pulmonary circulation is the part of the circulation, which carries oxygen depleted blood away from the heart, to lungs, and back to the heart. At first, in process

    Paleozoic Era The Houston Museum of Natural Science features Trilobites from the Middle Devonian, which were found in Silica Shale in Lucas County of Ohio. This particular genus of trilobites, “Eldredgeops milleri,” have large eyes containing a separately set lenses without a common cornea. Its thorax has 11 segments. Trilobites are some of the earliest known arthropods. Since these particular trilobites had good vision, I imagine that they were one of the few genus of trilobites that were either

  • The Evolution of Animals Essay

    4395 Words  | 18 Pages

    The Evolution of Animals Eukaryotes come in two grades of organization: single-celled (protists) and multicellular (plants, animals, and fungi). The world today is full of complex multicellular plants and animals: how, why, and when did they evolve from protists? Proterozoic Protists A single-celled eukaryote or protist can carry chlorophyll (it can be an autotrophic, photosynthetic, "alga"), it can eat other organisms (it can be an organotrophic, "protozoan" "animal"), or it may do both

  • Sensory System Analysis

    574 Words  | 3 Pages

    The sensory system plays a crucial role for organisms to survive by detecting environmental cues. In animals, the sensory signaling is largely mediated by chemoreceptors belonging to the GPCR superfamily [21], as well as by ion channels that mediate mechanosensation, thermosensation and others [89]. Chemosensory GPCRs in vertebrates are encoded by several gene families, which includes the olfactory receptors (ORs), vomeronasal receptor type 1 and 2 (VRs 1 and 2), taste receptor type 1 and 2 (TRs
