0/1 point earned What is one similarity between membrane carriers and pumps? Their regions that interact with the interior of the phospholipid bilayer are rich in hydrophilic R-groups. Their primary structure is made of nucleotides. They change shape as they pass molecules across a membrane. They are shaped to allow molecules of many sizes to pass through them.
Question 1 (12.5 points) A certain physical quantity, R, is calculated using the formula: $R = 4a^2(b-c)$ where a, b, and c are distances. What is the SI unit for R? m $m^2$ cm $m^3$ $cm^2$

10.56* Light from a laboratory sodium lamp has two strong yellow components at 589.5923 nm and 588.9953 nm. How far apart in the first-order spectrum will these two lines be on a screen 1.00 m from a grating having 10000 lines per centimeter?
Consider the equation $\frac{\partial u}{\partial t} + c \frac{\partial u}{\partial x} = \mu \frac{\partial^2 u}{\partial x^2}$ where $u = u(x, t)$ and $c$ and $\mu$ are positive constants. Would you expect hyperbolic (wavelike) or parabolic (diffusion-like) behavior of the solution?
1- For an adiabatic compression show that $a - PV^\gamma = const.$, where \\ $\gamma = \frac{t + 2}{t}$ and $b - \frac{dT}{dP} = \frac{2}{t + 2} \frac{T}{P}$. (2 pts)
Given the system function of a discrete-time filter at rest: 1 + z^(-1) The difference equation is: y[n] = x[n] + x[n-1] - 0.81y[n-1] y[n] = x[n] + x[n-1] - 0.81y[n-2] y[n] = x[n] + x[n-1] + 0.81y[n-2] y[n] = x[n] + x[n-1] + 0.81y[n-1]
