chemical stimulation. I would want to see what different chemicals would cause an action potential versus chemicals that would not cause an action potential. And‚ whether different amounts of a particular chemical would affect the action potential. 7. Why does the addition of sodium chloride elicit an action potential? Hint: Think about the sodium permeability of the neuron (Figure 3.2e). The addition of sodium chloride will increase the sodium ion concentration outside the cell membrane. The sodium

Respiratory Rate and Tidal Volume [pic] The total amount of air moved in and out of the lungs each minute (pulmonary ventilation) depends upon 2 factors: size of each breath (tidal volume) and number of breaths/minute (respiratory rate). For example‚ suppose your tidal volume is 500 mL (0.5 liters) and you breathe 15 times/minute. Your pulmonary ventilation = 15 breaths/min x 0.5 L/breath = 7.5 L/min. Pulmonary Ventilation = (Respiratory rate; breaths per minute) x Pulmonary Ventilation

RESPIRATORY PIGMENTS Colored‚ metal-containing proteins that combine reversibly with oxygen‚ found in the body fluids or tissues of multi-cellular invertebrate animals and microorganisms. The role of these pigments is primarily to aid in the transport of molecular oxygen. Thus they are distinguished from respiratory enzymes‚ which are concerned with the metabolic consumption of oxygen. Four distinctly colored groups of respiratory pigments exist among invertebrates: hemoglobins (purple‚ become orange-red

Week 7 Analysis of Electronic Payment Systems We have four electronic commerce (e-commerce) categories. The first category is Business-to-consumer (B2C) electronic commerce involves businesses selling goods or services to consumers. Walmart.com‚ Sears.com and Barnesandnoble.com are example of B2C e-commerce. The second category is Business-to-business (B2B). B2B e-commerce sells goods and services from one business to another business. Here is where businesses negotiate over prices for goods and
