1: List the symptoms and vectors (how spread) of the following disease:
* H1N1 (Swine Flu): Spread from mexico to the southern hemisphere it's a mild disease
* West Nile Virus: It is spread by mosquitoes and spreaded to the west hemisphere rarely caused severe symptoms
* SARS (Severe Acute Respiratory Syndrome): Started in China and spread to two dozen countries
2: Why are diseases that affect humans expected to increase in the future?
The more people on earth constitute a great resource for other species and other species will take advantage to infect us since it is easier with more people
3: Define the following:
* Population Dynamics: general study of population changes
* A Population: group of individuals of the same species living in the same area
* Species: all individuals capable of interbreeding
* Demography: study of human population
4: What are the 5 key properties of any population?
They are abundance, birth rates, death rates, growth rates, and age structure
5: What are the 4 phases of the human population?
Hunters and gathers, Early preindustrial agriculture, the machine game, the Modern era
6: Define the following terms:
*Crude Birth Rate: number of births per 1,000 individuals per year
*Crude Death Rate: number of deaths per 1,000 per year
*Crude Growth Rate: net number added per 1,000 per year or crude birth rate -crude death rate
* TFR (Total Fertility Rate): average number of children expected to be born to a woman
* Doubling Time: (define and calculate?) time for population to double
* Life Expectancy Rate: average time a person is expected to live
* GNP Per Capita: gross national product which includes the value of all domestic and foreign output
7: What is the S-shaped or Logistic Growth Curve?
It is the estimate of the population of animals
8: Explain this equation: P2 = P1 + (B - D) + (I - E)
It represents the population change in terms of actual numbers in population
9: Explain this equation: g = (B -D)/N or g = G/N
To know how rapidly tho population is growing using the birth rate and the death rate
10: What does an age-structure pyramid show?
It shows how many people of an age group live in an area
11: Summarize (one paragraph) The Prophecy of Thomas Malthus:
Thomas Malthus was a writer who was thought to be old fashioned until 2008 when he released an article that was in the front pages. He said the it is impossible to maintain a rapidly growing population. He pointed out that even in a perfect world nothing can expand forever not even the smartest species on earth. Our technology says that we can live with alot more people. We have options stop finding medicine that helps people live longer, reduce birth rate or do neither and see if Malthus's projection are true.
12: What is the demographic transition?
It is a three stage pattern of change in birth rates and death rates
13: What is the difference between a maximum lifetime and life expectancy?
Maximum lifetime is the maximum age that is possible to live and life expectancy is the average age someone is expected to live
14: Which country has the highest life expectancy? Who is 2nd?
The highest is the nation of Macau and the second is Japan
15: What is the life expectancy of the United States?
It is 78 years
16: Which country has the shortest life expectancy?
It is Swaziland
17: When discussing the carrying capacity of the Earth- What are the:
* Short-Term Factors: Solid erosion, a decline in groundwater and climate change
* Intermediate-Term Factors: desertification dispersal of certain pollutants, such as toxic metals
18: Explain how the carrying capacity of the Earth is a combination of science and of values.
Because it has the values of long term and intermediate factors and science such as medicine
19: What is the simplest and most effective means of slowing population growth?
The simplest and most effective way is age of first childbearing
20: Three characteristics of a population are the birth rate, growth rate, and death rate. How has each been affected by (a) modern medicine, (b) modern agriculture, and (c) modern industry?
a)Medicine has affected birth rate with birth control reducing it the death rate by letting people live longer and the growth rate by making the population size bigger
b)Modern agriculture has affected the birth rate by letting babies be born healthier, the death rate by letting people live longer and the growth rate increases
c) Industry increases the birth rate, increase death rate, and increases the growth rate
21: What is meant by the statement “What is good for an individual is not always good for a population”?
It means that something can make you healthier and live longer can increase the population in the world
22: What environmental factors are likely to increase the chances of an outbreak of an epidemic disease?
Contamination can make an epidemic and kill people
23:What is the demographic transition? When would one expect replacement-level fertility to be achieved—before, during, or after the demographic transition?
Pattern of change in birth and death rates, Before the demographic transition
24: Based on the history of human populations in various countries, how would you expect the following to change as per capita income increased: (a) birth rates, (b) death rates, (c) average family size, and (d) age structure of the population? Explain.
a) I'd expect it the birth rate to increase since they have more money they can provide more medicine to beat diseases
b) I'd expect the death rate to decrease since they have more money to have medicine
c) I'd expect it to decrease since more families will be able to afford birth control
d) I'd expect it to increase since the medicine they have will let them live longer
