Review Sheet Exercise 1 Cell Transport Mechanisms and Permeability Activity 1: Simulating Dialysis (Simple Diffusion) • Describe two variables that affect the rate of diffusion: Two variables that affect the rate of diffusion are size and concentration gradient. The molecular size vs the MWCO size of the membrane can either increase‚ decrease‚ or prevent diffusion. The greater the concentration gradient the greater the diffusion rate due to molecules moving from areas of higher concentration

Defense mechanisms‚ in psychoanalysis‚ are any of a variety of unconscious personality reactions which the ego uses to protect the conscious mind from threatening feelings and perceptions. Defense mechanisms can be psychologically healthy or maladaptive‚ but tension reduction is the overall goal in both cases(About). Primary defense mechanisms include repression and denial‚ which serve to prevent unacceptable ideas or impulses from entering the conscience. Secondary defense mechanisms-generally appearing

Transport Across The Plasma Membrane Intracellular Fluid (ICF) – The two thirds of your body fluid contained inside body cells. (Intra = within). The cytosol of the cell. Extracellular Fluid (ECF) – Fluid outside the body cells. (extra = outside). Interstitial Fluid – The ECF in tiny spaces between cells (inter = between). Plasma- the ECF in blood vessels. Lymph- The ECF in lymphatic vessels. Solute – Any material dissolved in fluid. Solvent- The fluid a Solute is dissolved in. Concentration

Mechanism description of Electric Iron introduction: An electric iron is a small appliance‚a handheld piece of equipment with a flat‚ roughly triangular metal surface that‚ when heated‚ is used to press clothes to remove creases. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are stretched and the fabric maintains its new shape when cool. description: The electric

Hematocrit Determination 1. Hematocrit values are usually ( *higher / lower ) in healthy males‚ compared to healthy females. Give one possible explanation for this. 2. Living at high elevations will cause a person’s hematocrit to ( *increase / decrease ). Explain your answer. 3. Long-term athletic training will cause a person’s hematocrit to ( *increase / decrease ). 4. What is anemia? Condition where inadequate oxygen is delivered to the body’s cells. 5. Anemia will cause a person’s

Team A will also identified four control mechanisms that are used‚ compare and contrast these control mechanisms‚ determine the effectiveness of the control mechanism‚ examine the positive and negative reactions and explain how these controls affect the four functions of management. The for control mechanisms are identified as setting performance standards’‚ internal audits‚ profit and loss statements‚ and feedback control

Glomerular Filtration Activity 1: Effect of Arteriole Diameter on Glomerular Filtration 1. Compare this data with your baseline data. How did increasing the afferent arteriole radius affect glomerular filtration rate? >>Increasing the afferent arteriole radius pushed the glomerular pressure‚ the glomerular filtration rate‚ and the volume of urine to be higher than the baseline data. Increasing the afferent arteriole radius increased the glomerular filtration rate. 2. Under

There are three main Anti-Clotting Mechanisms. 1. Non-Specific Mechanisms - Endothelial Factors a) Smoothness of Endothelial Lining prevents Platelet‚ adhesion and Extension of clot into the Blood Vessels. b) Negatively Charged Particles present over the lining of the endothelial repels the clotting factors ( Protein Anions ) i.e Prevents Clotting - Velocity of Circulation - If Decreased - Leads to clotting 2. Anti-Coagulant System - Has Enzymetic Pathways (natural anti

DESCRIBE THE STRUCTURAL COMPARTMENTATION OF MAMMALIAN CELLS AND THE DIFFERING FUNCTIONS OF THESE COMPARTMENTS? Mammalian cells are eukaryotic this means that all of their cells have common components‚ membrane bound organelles which prokaryotic cells do not this is shown in figure 1. Organelles are purpose made to carry out a specific function that is necessary within a cell. Due to the specificity of both conditions and concentrations with in these organelles these are compartmentalized. Encasing
