Future prediction of Brazil's population

By viewing the current state of Brazil, I predict that Brazil's population will grow in the next coming up years from 20 to 50 years. But there is low fertility rate and in the long-run, this will have a negative effect on Brazil's population because population will decrease gradually over a period of time and this may put the nation's future into danger as there will be lack of development which only humans are capable of doing. Brazil's approximate life expectancy is about 75.5 years. A male's life expectancy at birth is about 68 years while a female's is 76 which is more. An average male person's life is shorter and this may affect the future population.

Brazil's fertility rate is 2.18 children born/woman (2011). It has declined from previous data and years. This means that there will be more existence of old people and the young generation will start to disappear just like the old people. There will be fewer people to run the economy and the population will keep decreasing year by year.

Breeding Bunnies

Breeding Bunnies: Gene Frequency Data

• My predicting hypothesis for this lab was that the genes which contain F alleles are more likely to die. 
• Based on the lab data, no changes are needed because the prediction was correct.
• The dominant alleles are rabbits with characteristics such as thick fur and on the other hand, the recessive alleles are rabbits who sparse fur. The recessive alleles(f) will survive while the dominant alleles (F) will become extinct according to my hypothesis and experiment. The FF organisms have 1 organism while the ff organisms have 14 organisms (in the 3rd generation). Throughout these generations, the FF organisms decrease in number while on the other hand the ff organisms increase in number. 
• In the following generations, the bunnies with thick fur would survive and dominate which is also shown in the data collected. In the 3rd generation, f alleles have a frequency of .94 and the F alleles have a frequency of .06. 
• If there is high immigration, population will increase. If there is high emigration, population will decrease. If the weather changes; i.e it becomes warmer, then there will be a decrease in the population of rabbits with thick hair as they will emigrate to another cold area and there will be an increase of rabbits with scarce hair. Therefore, this situation will affect the gene pool. If the gene pool is high, then the population is most likely to survive. But if the gene pool is low, this may result in low population and possibly result in extinction.
•  My results may differ depending on the other group if they chose the upper or medium location on the mountain. 
• This stimulation is an example of evolution since it shows how bunnies with thick hair will adapt to the new environment when it gets warmer and how this will result as a change in the population. This shows a competition between two different groups of bunnies which are fighting to survive.
