potential. 3. 4. 5. K+ is more permeable than Na+ in a resting neuron. This is because there are few sodium leakage channels. 6. Since the resting membrane potential is the potential difference between the inside and outside of the cell across the membrane‚ a change would depend on the resting permeability of the membrane to ions. Activity #2 1. 2. Graded potentials can be said to be momentary‚ localized changes in the membrane potential that can be either depolarizing or hyperpolarizing. 3. In the

IMP 2 POW 3: Divisor Counting. I. Problem statement: This POW is all about finding information and patterns about the way divisors of certain numbers are found and expressed. In this POW when we talk about divisors we usually are counting the number of divisors that a number has. The divisor is a number that a number can be divided by‚ of course every number is divisible by every other number but in these problems we are only talking about whole‚ positive numbers. Every number is divisible evenly

Dry Wallum The dry wallum is a harsh environment that is battered by the sun and wind every day and with a base of porous sand; water availability is very scarce and must be conserved. The abiotic factors in the dry wallum are that the area is exposed to high amounts of sunlight which causes a loss of water in the leaves through transpiration. Since the wallum is so dry and hot; bush fires play a major cycle in the dry wallum which the trees have adapted to cope with. The roots of the plant and

Survival of the Sickest chapter two concentrates mainly on the disease named diabetes. The full scientific name is actually diabetes mellitus‚ or “passing through honey sweet” Diabetes is an extremely common and well known disease that becomes more and more common every day. The disease is based on sugar is the body‚ or glucose. When your body breaks down carbohydrates‚ it produces glucose‚ and essential sugar for the human body. There is a bodily function in which insulin helps the body use glucose

Mechanism 4 shows the debromination of 2α-bromocholestan-3-one to give 4. This mechanism which is similar to a Favoskii rearrangement‚ is likely to go via this path as other research has shown that there is often a by-product with this reaction. The by-product is cholest-4-en-3-one which requires the intermediate seen in the third molecule in the above mechanism. The intermediate is highly strained and with the presence of base a proton will be extracted which aids the collapse of the three membered

AP Chemistry Dr. Istone Lab 3: Gravimetric Analysis of a Metal Carbonate Lab Objective: In this lab we will determine the identity of a group 1 metal carbonate compound by gravimetric analysis. The unknown is weighed and dissolved in water and the precipitate is filtered‚ dried‚ and weighed. From the data the formula weight and identity of the unknown metal carbonate is determined. Lab Procedure: 1. Set up the Bunsen burner and ring clamp‚ light the burner and heat the crucible
