Then there is iodine‚ which is needed for the synthesis of the thyroid hormones. The other sources of minerals are zinc‚ which is needed for many enzymes and the activity of the numbers of vitamins and hormones. Others are sodium‚ chloride and potassium‚ which are electrolytes‚ which are good for regulating blood pressure. Water is considered a macronutrient. This macronutrient maintains our fluid balance and also the water that goes out of us is needs to be replaced by a certain intake taken back

Background In the Flame test lab we took a simple wire‚ looped it‚ and rinsed it in HCL (Hydrochloric Acid ). Then we dipped the wire in the different samples provided. The samples provided were Sodium‚Potassium‚Calcium‚ Barium‚ Strontium‚ Lithium ‚ and Copper II. Finally we put the wire loop into the flame of the bunsen burner. The flame erupted into many different colors for each specific sample. We then used the colors we recorded to find the two unknown samples given to us. But the question

muscle is made up of hundreds of motor units that are handled by different motor neurons that react at different levels of stimulation. The electric shock acts as an action potential by changing the membrane permeability allowing the sodium and potassium ions to pass through. At different levels of stimulation the motor neurons stimulate a motor unit and the more stimulation the more motor units become active. When the voltage was set at 0 or .1 there was no reaction because the shock wasn’t able

Question #5 Unlike their friend Jemima‚ the other patients have all experienced a drop in blood pressure (Hypotension) and have an elevated heart rate (125-135 bpm) Hypertension occurs when blood pressure drops below 90 mm Hg systolic or 60 mm Hg diastolic number. Due to the girls all consuming substances that affect their bodies to normally retain water‚ they have all suffered similar symptoms but to different degrees. Dehydration causes the volume of blood circulating through the body to decrease

acid and base-forming ions. The acid forming cations are positively charged ions they commonly include hydrogen ions‚ aluminium ions ‚and iron(II and III ions). Base forming cations commonly comprise of calcium ions‚ magnesium ions‚ sodium ions and potassium ions. It is also known that the CEC is positively correlated with soil pH. As the dilution of the soil solution increases‚ the pH is also seen to increase. The effect of adding water and occasional mixing during the 30 minute period is to allow

Robert Lawrence and Edmund Stephens‚ two graduate students of geology from Columbia University‚ organized the Saline Salt Company in 1974. Keeping in mind the fact that every 1‚000 grams of seawater contains approximately 35 grams of various salts‚ the two men pictured limitless wealth for themselves by extracting these salts. Common table salt comprises 27 grams out of each 35 grams and is easy to extract; so‚ the men decided to begin producing it. They picked New Iberia‚ Louisiana as the ideal
