Question 60 (Mandatory) What would be the growth rate of an island population of 1,000 that has 30 births per 100 population, 20 death per 100 population, 5 immigrants per 100 population, and 10 emigrants per 100 population? (you can write on your exam) a) 50 b) -5 c) +5 d) + 100 e) +50

Question 19

Question 3: I introduced 2 species of super-mutant ant species into my terrarium. These are the only species competing for resources.  Species 1's common name is the TEN-headed ZINGer ant and they have a population size of N1 and a carrying capacity of K1. The blue line shows the isocline for species 1. Species 2's common name is the Evil Ant. The population size of species 2 is N2 and the carrying capacity is K2. The green line shows the isocline for species 2 The red dot is the present combination of N1 and N2.  Part a) Given the data how will the population of both species (N1 and N2) change- pick the correct colored arrow (pink, brown, black, or red) to show the direction that the combination of N1 and N2 will change

Question 2

Question 5 What element of PICO is missing from the following quantitative question: Do rehabilitation units result in long term increased quality of life compared to medical units? Question 5 options: Population Intervention Control Outcome

22500A what changes have happened technologically, medically, Culturally and nutritionally that results in major population changes over time?

Question 1. Is the population in H-W equilibrium? Observed genotype frequencies ● ■ ● f[A₁A₁] =0.16 f[A₁A₂] =0.48 f[A₂A₂] =0.36 O Question 2. Is the population in H-W equilibrium? Observed genotype frequencies f[A₁A₁] =0.04 f[A₁A₂] =0.12 ● f[A₂A₂] =0.84 ● Question 3. Is the population in H-W equilibrium? Observed genotype numbers A₁A₁ =40 A1A2 =20 ● A₂A2 =40 O Question 4: Is the population in H-W equilibrium? Observed number of each genotype A1A1=36 ● ● A1A2=28 A2A2=36 Note that raw numbers are given. The question is whether observed frequencies = expected frequencies. You must first compute the genotype frequencies.

QUESTION 2: Population size One weekend in early July, a total of 154 Marbled White butterflies were captured and marked before being released. The following weekend, the butterfly traps captured another 87 butterflies, but only one was marked. a) Based on these data, estimate the butterfly population size (show your workings in full). b) Estimate the population size if, instead of one, the number of marked butterflies was: i) 2 ii) 10 iii) 25 You do not need to show your workings for this part. c) Would all of these results give equally accurate estimates of population size? Explain your reasoning. d) The following year, the researcher returned to the same spot, on the same July weekend in order to evaluate whether the butterfly population size was similar year-on-year. This time, however, the recapture phase occurred only three days after marking. Do you think this would affect the accuracy? Explain your answer fully.
