BIOL 2460 Chapter 9: Microbial Growth Graded A+ Most common form of bacterial reproduction Binary fission 4 Basic Steps of Binary Fission 1. Growth of cell size and increase in cell components 2. Replication of DNA/chromosomes 3. Division of cytoplasm (cytokinesis) 4. Septum formation and division of daughter cells Cytokinesis is directed by the ___________ protein. FtsZ Where is the Z ring assembled during binary fission? On the cytoplasmic membrane Divisome activates the...

Signs objective and measurable. Can be measured by a clinician. -body temp. (98.6 F) -heart rate (60-100 beats per minute) -breathing rate (12-18 breaths per minute) -blood pressure (between 90/60 and 120/80 mm Hg) Symptoms Subjective. Felt by the patient but cannot be clinically confirmed or objectively measured. -nausea -loss of appetite -pain Wong-Baker FACES Pain Rating Scale Rate pain on a scale from 0-10 Syndrome A specific group of signs and symptoms characteristic of a particular dise...
