BIO- FINAL EXAM REVEW SHEET This is a comprehensive review of material from exams 1-3. Please study your class notes/powerpoint slides and read the chapters listed in your syllabus to study for all new material. What are the characteristics of living organisms? Acquire and use energy Made up of other cells Process information Can replicate itself (can reproduce) Population evolves (they evolve) What are the characteristics of cells?

change in pH. Also‚ presumably the buffer will have the right concentrations of salt or electrolyte’s (ion such as Na‚ K‚ Ca‚ etc.)- that is‚ the solution and the beetroot cells must be isotonic‚ so the buffer must be used for each trial-to ensure that the beetroot cell doesn’t lyse due to being placed in hypotonic solution Additional controls Time: Amount of time beetroot sample remains in a test tube must remain the same for each trial Cutting Beetroot: Results could be affected by pigment released

PATHOPHYSIOLOGY FOR THE HEALTH PROFESSIONS CHAPTER 6: FLUID‚ ELECTROLYTE‚ AND ACID-BASE IMBALANCES Fluid Imbalance Review of Fluid Imbalance -Water carries nutrients into cells and removes wastes‚ transports enzymes in digestive secretions‚ and moves blood cells around the body. Fluid Compartments -Approximatley 60% of an adult’s body weight consists of water -Infant’s body weight is about 70% -Fluid is distributed between the intracellular compartment (ICF)‚ or fluid inside the

Bio 93 Review Sheet: 1. Understand all the THEMES presented in the introductory lecture (lec 1). 2. What is an open system? Energy in and out‚ comes in and leaves as heat 3. What are the 4 most important elements in the human body? C‚ O‚ N‚ H 4. Draw the periodic square for Helium. How many valence electrons does it have? How do you figure this out using the periodic table? Two valence e-‚ 23He‚ all the way right full shell only holds two electrons 5. What is an isotope? How are they used

Lab One – Diffusion and Osmosis SECTION ONE: Methods Lab 1 – Diffusion and Osmosis can be broken down into four parts (A‚ B‚ C‚ and D). Lab 1A – Diffusion In this exercise‚ we tested diffusion through dialysis tubing. This was done through a demo with the teacher‚ rather than individually in groups. First‚ a piece of 2.5cm dialysis tubing was obtained. Then one end was folded and clipped securely so that a solution poured into the bag would not leak out. Next‚ the other side of the bag was

* A reactant in an enzyme-catalyzed reaction is called a substrate. The area of the enzyme that binds to the substrate is called the active site - where the action takes place. * Cofactors and coenzymes are small molecules or ions that help enzymes to act. HSC Biology Notes – Hugh Phillips Maintaining a Balance 1.Most organisms are active in a limited temperature range: Identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their

greater outside the cell compared to the inside of the cell‚ therefore water will diffuse into the cell by a process of osmosis. The opposite however will occur when the water potential outside the cell is lower than that inside the cell (i.e. with hypotonic solutions‚ such as a solution with a sucrose concentration of 1m and 0.75m). This is due to the water potential outside the cell being less than that inside the cell and therefore water moves out of the cell by osmosis. With a larger water potential

EXPERIMENT 1 COLLIGATIVE PROPERTIES OF SOLUTIONS Date: December 03‚ 2013 Locker 21 Members: Vanessa Olga Dagondon Christine Anne Jomocan Janica Mae Laviste Nablo Ken Menez A. TYPES OF DISPERSED SYSTEMS Results and Discussion The first part of the experiment aims to differentiate the different dispersion systems. In this experment‚ three systems are introduced: true solution‚ colloidal dispersion and coarse mixture. The said three systems are classified through a property of colloids known as the
