Respiratory Acidosis and Alkalosis Activity 1: Normal Breathing 1. At 20 seconds‚ pH = 7.41 2. At 40 seconds‚ pH = 7.38 3. At 60 seconds‚ pH = 7.39 4. Did the pH level of the blood change at all during normal breathing? If so‚ how? Yes it did. It went down and then back up a little bit. 5. Was the pH level always within the “normal” range for the human body? yes 6. Did the PCO2 level change during the course of normal breathing? If so‚ how? No it did not Activity 2a: Hyperventilation

the Cobalt Used in Lithium-ion Batteries? In our modern world today‚ mankind’s surge in technological advances has made batteries a ubiquitous necessity in our daily lifestyles. The most popular form of battery is the lithium-ion (Li-ion) battery (Brain)‚ which is used an array of devices ranging from laptops and cellphones (Brain) to electric cars (Puiu). However‚ there is a need at the moment to develop a more sustainable and environmentally friendly lithium-ion battery. This is because the

A patient is admitted for electroconvulsive treatment (ECT). The physician orders the neuromuscular blocking agent metocurine iodide (Metubine) to reduce trauma by relaxing skeletal muscles. Explain the process of muscle contraction and how a neuromuscular blocking agent‚ such as Metubine‚ would interfere with muscle contraction. In order to understand how a neuromuscular blocking agent works one must first understand the process of muscle contraction and what has to take place in order for us

An investigation to find out what factors affect the rate of electrolysis of a solution containing copper (II) ions. Plan It is known that by passing a constant electric current through a copper sulphate solution the passage of ions through this solution results in copper atoms being dissolved into the solution from the anode‚ which has a positive charge while positive copper‚ ions (cations) are also being discharged at the cathode which has a negative charge. Normally anions‚ which have a negative
