In the fruit fly salt tolerance experiment, which of the following is true? Inbred Stock: Creates almost genetically identical flies: propagated by by single pair sibling matings [control] Unstressed line: founded by the inbred stock and kept at large population for 30 generations. [mutation] Salt-stressed line: founded by the inbred stock, kept at large population, and stressed with salted food (<4%) for 30 generations. [mutation + selection] Group of answer choices Mutation rate for salt tolerance is the same in the salt-stressed and unstressed lines Salt stress induced the mutation for salt tolerance Mutation rate for salt tolerance is higher in the salt-stressed lines Evolution happen only in the salt-stressed lines

You want to establish an account from which you can withdraw $200 weekly for 4 years. The account will invest at 8.1% per year compounded weekly. How large must the account be? Part 1 of 2 Which formula should be used to find how large the account must be? O A. $I = Prt$ O B. $A = P(1+rt)$ O C. $A = P(1+i)^n$, $i = \frac{r}{m}$, $n = mt$ O D. $r_{eff} = (1 + \frac{r}{m})^m - 1$ O E. $r_{eff} = (\frac{A}{P})^{1/t} - 1$ O F. $S = R[\frac{(1+i)^n - 1}{i}]$ O G. $P = R[\frac{1 - (1+i)^{-n}}{i}]$
A planar stress element has the stress state: $\sigma_x = 25$ MPa, $\sigma_y = 42$ MPa and $\tau_{xy} = 49$ MPa. The stress element is cut at an angle of $\theta = 40$ deg. The cut surface has an area of 1 mm$^2$. What is the value of the normal force applied to the bottom of the stress element? Units for your solution will be N. Area of sliced face = 1mm$^2$ Answer: 80.28 \times (27.00)
