A Tour of the Cell Chapter 6 Concept 6.2: Eukaryotic cells have internal membranes that compartmentalize their functions The basic structural and functional unit of every organism is one of two types of cells: prokaryotic or eukaryotic Only organisms of the domains Bacteria and Archaea consist of prokaryotic cells Protists, fungi, animals, and plants all consist of eukaryotic cells ? 2011 Pearson Education, Inc. Comparing Prokaryotic and Eukaryotic Cells Basic features of all cells Plasma membrane Semifluid substance called cytosol Chromosomes (carry genes) Ribosomes (make proteins) ? 2011 Pearson Education, Inc. Prokaryotic cells are characterized by having No nucleus DNA in an unbound region called the nucleoid No membrane-bound organelles

Myology - study of muscles Kinesiology- study of movement of human body Types of muscle tissue - differ from one another by microscopic anatomy, location, and control by the nervous systemMyology skeletal muscle - (striated) attached to bone, multi-nucleated, voluntary\ cardiac muscle - only in heart, striated, 1-2 nuclei, involuntary smooth muscle - (visceral) walls of hollow internal structures, non-striated, one nucleus, involuntary Functions of Muscle Tissue locomotion - movement of the body motion - movement of substances within the body maintenance of posture thermogenesis - muscle contractions produce 85% of all body heat Organization of Skeletal Muscle all skeletal muscle is protected by deep fascia, which surrounds the muscle and holds muscle tissue together

3/22/16 Cytoskeleton - a system of protein filaments that extend through cytosol The cytoskeleton helps support the large volume of cytosol inside a cell Most prominent in eukaryotic cells However, unlike our static skeleton, the cytoskeleton is dynamic Cytoskeletal filaments are made of noncovalently-linked subunits *allows for rapid assembly and disassembly* Filaments can disassemble and reassemble in different locations in cell Cytoskeleton Functions maintains cell SHAPE & RIGIDITY A framework connecting the plasma membrane to the organelles CELLULAR MOVEMENT MOTILITY: whole cell i.e. amoeba or sperm ? cilia/flagella intracellular structures - chromosomes, vesicles CONTRACTILITY - movement involving contraction of a cell muscle - tissue, cleavage furrow.

Forensics chapter 1

Welcome to Forensics Mr. Rizzo What is forensics Science? Use of the scientific method in the legal arena. The transfer of scientific techniques to aid the legal process. The use of science and technology to provide evidence. When is forensics Science used? ? To solve any problem whether criminal or historical in nature. What is Evidence? Must be relevant to the case at hand. Must be more probative than prejudicial on the issue. ?Probative evidence: tending to prove a particular proposition or to persuade you of the truth of an allegation Forensic Evidence? IT IS NOT CSI?. Is used to establish whether a particular person or thing COULD be at a particular place at a specific time. Hieronymus Bosch 1450-1516
