One rabbit has the dominant allele for brown fur and the recessive allele for black fur. Another rabbit has two recessive alleles. If the two rabbits have offspring, what are the odds of one of the offspring having brown fur? A. 25% B. 50% C. 75% D. 100%

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
