The population in a country with a total fertility rate of 4, a low death rate and a immigration rate that equals the emigration rate is
unpredictable
increasing
stable
decreasing
ans: increasing
Basically, the population growth = births - deaths + immigration - emigration
as immigration rate that equals the emigration rate and death rate low then increasing the population.

1. During stage 2 of the demographic transition model death rates and birth rates remain high death rates decline, while birth rates remain high the population is typically decreasing in size death and birth rates are increasing birth rates decline rapidly 2. The population in a country with a total fertility rate of 4, a low death rate and a immigration rate that equals the emigration rate is unpredictable increasing stable decreasing

Which of the following is not involved in determining population growth? birth death emigration immigration E. organism size
3.TFR and Birth Rates: a.Define the crude birth-rate and the total fertility rate Suppose country A and B have are identical in their population size and structure, and rate of mortality, but A has a higher average TFR than B. b.What could be some of the reasons why A has a higher fertility rate than B? c.What will be true about the size and age structure of the population in A relative to B in 25 years? Will the proportion...

Question 2 (1 point) It is estimated that the replacement rate of a country is 2.11. Which of the following total fertility rate will cause a declining population growth? Fertility rate equals to 3.24. Fertility rate equals to 1.52. Fertility rate equals to 2.11 Question 3 (1 point) Saved Tianwei needs to decide whether to install solar panel in her new house Installation costs her $200 now but the solar panels can save her $50 every year.

that is all the information that is given on the worksheet
More Calculating Population Size Populations of any organism can be analyzed mathematically. Population biologists are interested in characteristics such as doubling time, growth rate, carrying capacity, and total population at the end of a given amount of time. These calculations depend on such variables as birth and death rate, immigration and emigration, and initial population size. Use the following formulas to find the population size for each of the...
What is carrying capacity? A) the minimum population size that s particular environment can handle B) the maximum population size that a particular environment can handle C) when the population growth rate is increasing exponentially Logistical growth is density dependent. What would be the best explanation for the leveling off of the curve as you approach carry capacity? A) decrease in birth rates only B) increase in death rates only C) both a decrease in birth rates and increase in...
