Dr Mifflin has been studying the species Nerviosa complera. She has found that while members of this species have plenty of food and are not resource limited, they get extremely agitated when they are crowded, and their reproduction falls off rapidly. She has studied the growth rate of the population as a function of population size, n), and has observed that it changes according to the function Rn a, b > 0. 1+bn' a) Formulate a model that describes the...
You are studying two SNPs each with two alleles (A and C; G and T). You cross an AA GG individual with an CC TT individual to generate a doubly heterozygous pool of offspring (the F1). You cross these doubly heterozygous individuals with each other. Imagine it is possible to sample the gametes of these double heterozygotes. If the SNPs are fully unlinked what haplotypes should you observe in the gametes, and in what frequency? 1. What is D in...

B. Dr. Bennett's dunk tank with a 12 ft2 cross-sectional area has a drain hole at the bottom of the tank with an area of 0.09 ft. If the water has an initial height of 3.8 ft, how long will it take to completely drain the tank? (include units with answer) Format Check C. A spherical object falls through a fluid with a viscosity of 240 mPa-s. As the object moves at 4.9 m/s, it experiences a drag force of...
