Question 3-10 points One of the most important functions of the membrane in living cells is its ability to selectively pass either sodium ions (Na) or potassium ions (K) through channels in the membrane. These ions have the same charge +le). The electric force exerted on them by the membrane will be similar. In addition, they are about the same size (RNa~0.12 nm, RK 0.15 nm). So how can channels in the membrane distinguish between them? One mechanism that has...

1.Define what a linear program/linear programing model is including its three key characteristics. Be sure to state those characteristics fully. 2.Some models are deterministic while others are stochastic. Discuss two key differences between deterministic models and stochastic models. Then further demonstrate your understanding of these two different kinds of models by providing an example of a stochastic model including at least two input variables and an example of a deterministic model including at least two input variables. 3.Every linear program/linear...

1. "Quackism" is a recently discovered element with the symbol Q. It is located in group 7A of the periodic table, in the same group as bromine, chlorine and iodine. How many valence electrons are associated with QO3- ? (I call this e- math in the lecture videos.) Apart from one atom of quackism, the ion also contains 3 oxygen atoms. Also, please take note of the very small negative sign on the formula of the compound. 2. "Quackism" is...
