Question 4 1.2/2 pts 1-2 98 Details Score on last try: 1.2 of 2 pts. See Details for more. You can retry this question below. Consider the vector field F = (10xy, 5x^2 + 18y^2). The vector field is not conservative. The vector field is conservative, and the potential function such that f(0,0) = 0 for F is f(x,y) = 5x^2y + 6y^3 + K. If F is conservative, use f(x,y) to evaluate ∫_C F · dr along a piecewise smooth curve (C) from (-1,-1) to (4,4). ∫_C F · dr = 0^(8)

1.A. Heterozygotes possessing one brca1 loss-of-function mutant allele exhibit the cancer phenotype; the homozygous condition is lethal. The heterozygous genotype is incompletely penetrant with many not being afflicted with breast or ovarian cancer. Given what we know about cancer, why might the brca1 heterozygotes be incompletely penetrant? B. On Mars, the BRCA1 gene is paternally imprinted but is otherwise similar to BRCA1 on Earth. A male of unknown genotype mates with a female of unknown genotype. Among the progeny that are alive, what proportion will have cancer (assuming 100% penetrance)? Show your work.

12. To solve the following you will need to identify the reference angle and then identify the solutions. All solutions need to be in radians and between 0 and $2\pi$. Round any value to three decimal places if you can't give an exact answer. (6 points each) a. $sin(\theta) = 0.427$ $\theta = 0.441$ $sin^{-1}(0.427) \approx 0.441$ $\theta \approx 2.701$ $\theta \approx 0.441$ $\theta \approx 2.701$ b. $3.1csc(\theta) + 47 = 0$ $3.1csc(\theta) = -47$ $csc(\theta) = -\frac{47}{3.1}$ $sin(\theta) = -\frac{3.1}{47}$ $sin^{-1}(-\frac{3.1}{47}) \approx -0.066$ $\theta \approx -0.066$ $\theta \approx -0.066 + 2\pi \approx 6.217$ c. $2(x) - \sqrt{3}cos(x) = 0$ $2x = \sqrt{3}cos(x)$ $\frac{2x}{\sqrt{3}} = cos(x)$ Extra Credit: Solve the following equation.

When you have finished looking at all of the fossils from the Miocene: 1) Draw a circle around the hominoid clade, and Proconsul, 2) After completing stations 4-6, mark where you think the fossil primates Sivapithecus, and Gigantopithecus best fit. Note: because they are fossils, they do not need to be listed at the top with the other primates, but can be drawn onto any lineage or as a side branch. Aegyptopithecus is drawn in as an example.
