crystal carefully you will see it looks like a cube because salt crystals are cubic but not all crystals are cubic‚ some can be triangular. Salt crystals are cubic because salt is made of equal amounts of Na and Cl ions which are bound together by electrostatic forces‚ or opposites attract. The crystals wants as few nearest links possible broken so the best way for a salt crystal to be broken is one link per atom compared to the worst which is three links per atom. When a salt crystal is broken along

Week Five Textbook Exercises Geoffrey Anderson PHY/101 December 9‚ 2014 Mr. Craig Spencer Week Five Textbook Exercises Chapter 22: Electrostatics 8) When combing your hair‚ you scuff electrons from your hair onto the comb. Is your hair then positively or negatively charged? How about the comb? -The hair becomes positively charged and the comb becomes negatively charged; since‚ the electrons went from your hair to the comb and the more electrons there is makes an object more negative. 18)

force‚ with a rope/ string * Normal force: only when in contact with something ie. The ground. Points away from surface * Friction: opposes the sliding of two surfaces cross one another. Act opposite to the motion/ attempt at motion (electrostatic forces) * Force diagram-show all forces acting on object Newtons first Law: * Inertia: proportional to mass of the object‚ every object wants to maintain their state of motion‚ resists change in motion (stay in constant motion)

“Denaturation of Proteins” Denaturation is a process in which proteins or nucleic acids lose the tertiary structure and secondary structure which is present in their native state‚ by application of some external stress or compound such as a strong acid or base‚ a concentrated inorganic salt‚ an organic solvent (e.g.‚ alcohol or chloroform)‚ or heat. If proteins in a living cell are denatured‚ this results in disruption of cell activity and possibly cell death. Denatured proteins

An ionic bond is an electrostatic attraction between oppositely charged ions. Dot-cross diagrams show outer electrons only e.g. NaCl [pic][pic] ▪ Covalent bonding – A covalent bond is a shared pair of electrons. Only non-metals can get a full shell by sharing electrons

salts have a multivalent anions like sulphate or phosphate with cations like sodium or ammonium."(Scopes‚ 1994) Ion Exchanges The Ion exchanges exploit the different net charges on proteins at a given pH and interact with the proteins on electrostatic attraction (Scopes‚ 1994). The carboxymethycellulose (CMC) is a cation exchange that is chemical weak. It has a negative charged carboxyl groups‚ they are active above the pH of 4.5.

Research has determined that ageing is important to consider when looking at neurodegenerative diseases and there cause‚ such as Alzheimer’s disease. It is thought that neuronal loss is primarily involved in neurodegeneration when in fact it seems that synaptic strength‚ or plasticity‚ is more vulnerable to the process of ageing (1). Biochemical and structural alterations of the synapse such as changes in lipid composition in certain areas of the brain are also thought to be associated with this
