Ion

(Ions). At this time upper and lower Egypt were united under one ruler. Contrary to Heliopolitan cosmogony, Memphite cosmogony believes the supreme creator is Ptah. All the info archaeologist obtained was from the Shabaka Stone. The great god Ptah also goes…

help us see, hear, taste, and feel sensation. This is all do to a critical phenomenon known as action potential. Action potential is caused by a change in various ions, specifically sodium and potassium. When the neuron is in a resting state with -70mV, there is a great amount of potassium ions inside the cell, and a plethora of sodium ions outside the cell. For something to initiate an action potential, there must be a certain stimulus or impulse. This stimulus would cause voltage-gated sodium…

additives, descaling, and leather processing. About 20 million tonnes of hydrochloric acid are produced worldwide annually. Chemical properties and reactions: Hydrogen chloride (HCl) is a monoprotic acid, which means it can dissociate to give up one H+ ion. In aqueous hydrochloric acid, the H+ joins a water…

Which metals produce similar flame colors (according to your naked eye)? NaCl and NaNo3 both turned the color orange. 2. What metal ions are in the unknown solutions A and B from the barrels on the vacant lot? Clearly, and in detail, explain your reasoning. The metal ions BsCl and LiCl are in the unknown solutions A and B from the barrels on the vacant lot. 3. A student performed flame tests on several unknown substances and observed that all of the flame colors were shades of red.…

is a flow of electrons from the positive to the negative electrodes. From the anode to the cathode. From the graphite to the copper. The cations in this experiment which is the sulphate and hydroxide will migrate to the negatively ions or cathode copper . Positive ions are attracted to the negative electrode, gain electrons so are reduced. This is…

hydrogels Hydrogel swells in response to an electrical stimulus with a mechanism very similar to pH, experiences shrinkage, and bending. The major difference between electrical and pH stimulations is that the electric field moves mobile ions in order to regulate an ion concentration gradient through the hydrogel and the solution [54,55]. Polymeric networks containing ionizable groups can have important electrical behavior under an electric field. The electrosensitive hydrogels experience…

Lead is a toxic metal that can enter the body by inhalation of lead dust or ingestion when touching the mouth with lead-contaminated hands. If leaked onto the ground, acid and lead particles contaminate the soil and become airborne when dry. Children and fetuses of pregnant women are most vulnerable to lead exposure because their bodies are developing. Excessive levels of lead can affect a child’s growth, cause brain damage, harm kidneys, impair hearing and induce behavioral problems. In adults,…

This paper will discuss the management practices that can be implicated to help control the severity of Hyperkalemic Periodic Paralysis in affected horses. Because of the debilitating effects that this condition has, it is important to examine the ways that this disorder can be controlled. Low potassium diets, regular turnout, and a constant schedule have been shown to effectively manage the condition of Hyperkalemic Periodic Paralysis. The role of potassium in action potentials, as well as in…

Introduction Part I: The first lab experiment used ion-exchange chromatography to purify a protein mix. Ion-exchange chromatography is the process of separating charged molecules based on their attraction to the charge of the beads in the column. The experiment used DEAE beads, diethylaminoethyl, which are used for anion exchange. Basically the beads are positive. Once the protein mix is added to the chromatography column the negative ions (anions) will stick to the DEAE beads and the rest will…

players that help mediate necrosis include ROS, Calcium ions, poly-ADP-ribose-polymerase (PARP), and lysosomal proteases (888). PARP is an enzyme that is responsible for repairing DNA damage, such as strand breaks. Cells that have undergone a traumatic cellular insult typically have damaged DNA. PARP will deplete cellular ATP in an attempt to repair the massive damage to DNA. Several proteases are activated by increased cellular calcium ion concentration that degraded important cellular proteins…
