Outline the four stages of the demographic transition as it occurred in Europe and North America.
Ivanshal [37]

Answer:

Stage 1—High birth and death rates lead to slow population growth.

Stage 2—The death rate falls but the birth rate remains high, leading to faster population growth.

Stage 3—The birth rate starts to fall, so population growth starts to slow.

Stage 4—The birth rate reaches the same low level as the death rate, so population growth slows to zero.

Describe how an organism has 2 sets of dna and the importance of homologous chromosomes
LenKa [72]
Most organisms are Diploid, and as a result, they will have received 2 copies of the chromosomes, or sets of chromosomes, from both their parents. This they will have 2 sets of Genes that will perform almost exact same process, except with different phenotypes.

These chromosomes need to be homologous, in order for new alleles and other genetic combinations to be made.

Answer

#1. A reduction in habitat for arctic seals will reduce the population of arctic seals. This will reduce the capture efficiency for killer whales preying on arctic seals because there will be fewer to capture. A reduction in habitat for arctic seals will lower the carrying capacity for arctic seals because there is less habitat. A reduction in arctic seals, the food for killer whales, will reduce the carrying capacity for killer whales, unless there is a substitute source of food.

#2. If there is another source of food for killer whales, the population of killer whales will probably remain the same, if they were at their carrying capacity and their habitat remains the same. If there is another source of food for killer whales, the population of arctic seals will still decrease, because the habitat for arctic seals has decreased, and habitat is independent of predator population.

#3. There are many limitations on any simulation. The computer only uses the parameters in the program, so changes in ocean temperature, weather patterns, salinity changes, food supply, habitat, interaction with other species and presence of plants and zooplankton are not considered. All of those can change and change the results.
