as we discussed during the lecture at the genetics cause changes and how we express our genes based on that discussion as a surrogate mother who carries an embryo created from an egg of another woman have a direct effect on the gene expression of that child. Why no because genetic effects are silenced by the father sperm no because mitochondrial DNA is only provided by the genetic mother. Yes because genetic effects of the genetic mother are suppressed by the father sperm yes because lifestyle choices make the surrogate mother may affect chromatin structure no because the surrogate mother cannot pass down any gene to the baby.

9. Bicycle Sales The probability that a bicycle shop sells 0, 1, 2, or 3 bicycles in a week is 3/8, 1/4, 1/4, and 1/8, respectively. Find the mean, variance, and standard deviation for the distribution. $\mu = E(X) = \sum [X \* P(X)]$ $\sigma^2 = E(X^2) - \mu^2 = \sum [X^2 \* P(X)] - \mu^2$ $\sigma = \sqrt{\sigma^2}$ X P(X) X * P(X) X$^2$ * P(X) Mean or expected value: 0 1 2 3 $\mu = E(X) = \sum[ X \* P(X)] = $ Variance: $E(X^2) = \sum[ X^2 \* P(X)] = $ $\sigma^2 = E(X^2) - \mu^2 = $ Standard deviation: $\sigma = $
You have probably seen little packets of silica gel particles to absorb water in all kinds of food and consumer products. Imagine that a 2mm diameter particle is in a rapidly flowing air stream at a velocity of 50c(m)/(s) containing 1.0 mole% of H2O vapor. The pressure of 1.0atm and temperature of 25deg C. At equilibrium, water vapor has a linear solubility in silica gel, c_(W)^(**)=SP_(w), where S=2.0(mol)/(cm^(3)(atm)). At 25deg C, the diffusion coefficient of H2O in the silica gel is 1.0 imes 10^(-6)cm(2)/(s). Initally, the silica contains no H2O. Assume that the partial pressure of H2O vapor in the gas stream remains constant. a. What is the mass transfer coefficient for water vapor in air? b. Use your answer to a to find the Biot number for system. Is this system limited by external convection or internal diffusion? c. Use charts to find the concentration of H2O in the center of the silica gel bead after 1hr. 4. You have probably seen little packets of silica gel particles to absorb water in all kinds of food and consumer products. Imagine that a 2mm diameter particle is in a rapidly flowing air stream at a velocity of 50 cm/s containing 1.0 mole% of H20 vapor. The pressure of 1.0 atm and temperature of 25'C. At equilibrium, water vapor has a mol linear solubility in silica gel, cw = SPw, where S = 2.0- At 25C, the diffusion coefficient of H2O in the cm3atm silica gel is 1.0x10- cm2/s. Initally, the silica contains no H20. Assume that the partial pressure of H20 vapor in the gas stream remains constant. a. What is the mass transfer coefficient for water vapor in air? b. Use your answer to a to find the Biot number for system. Is this system limited by external convection or internal diffusion? c. Use charts to find the concentration of H20 in the center of the silica gel bead after 1 hr.
Find the maximum value of -x + 2y + 5z as (x, y, z) varies among points in {(x, y, z) in R^3: ||(x, y, z)|| = 1}. 1. Find the maximum value of x + 2y + 5z as (x, y, z) varies among points in {(x, y, z) in R^3: ||(x, y, z)|| = 1}.
