Explain how our population can still be growing when the birth rate has been about 1.6 children per woman since the 1980s. b. List two factors that likely contribute to Canada's relatively low birth rate of about 1.6 children per woman and describe how each factor can affect the birth rate. c. If Canada's population were to start declining in the next few years, would this automatically translate into a lower ecological footprint for the average Canadian? Explain your answer. 10

Use the simulation to test your prediction before committing to one of the four options. a.The overall size of the curve will increase in the same proportion at every age. b.The overall size of the curve will decrease in the same proportion at every age. c.The size of the curve will increase at every age, but with the greatest change at the older ages. d.The size of the curve will primarily in the range of ages from 20 to 40.
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.
S2) Below are two tables showing the population size and deaths by age for one year in the states of Louisiana (LA) and Florida (FL). Use the data to answer the following questions. You may use the blank cells in the tables for calculations and to show answers Age group 0-15 16-70 71+ Louisiana Deaths 30 215 585 Florida Age group Deaths 0-15 16-70 71+ 25 400 725 Population 165,000 300,000 75,000 Population 90,000 435,000 225,000 a. Calculate the overall crude mortality rates for LA and FL expressed as per 100,000 population. LA: FL: b. Calculate the age-adjusted mortality rates using the combined population as the standard. c. Explain what accounts for this difference in crude rates and adjusted rates between LA and FL.
The moose population in Northern Alberta is estimated to be around 11, 800. During the year, there were 5330 births, 4809 deaths, 12 immigrations and 45 emigrations. Calculate the per capita growth rate. Express your answer as a value between 0 and 1 rounded to two decimal places. If the population is decreasing indicate this with a negative sign.
Determine which of the following passages are arguments. For those that are, identify the conclusion. For those that are not, determine the kind of nonargument.★1. The turkey vulture is called by that name because its red featherless head resembles the head of a wild turkey. 2. If public education fails to improve the quality of instruction in both primary and secondary schools, then it is likely that it will lose additional students to the private sector in the years ahead. 3. Freedom of the press is the most important of our constitutionally guaranteed freedoms. Without it, our other freedoms would be immediately threatened. Furthermore, it provides the fulcrum for the advancement of new freedoms.

How would you describe human population growth for the past 200 years. When determining Earth’s carrying capacity for humans, why is it not enough to just consider human numbers? What will happen if there is a rapid growth in human population? What solutions do you have in mind to limit the human population growth?
