Ответ:
a) If you measured the total lifetime Darwinian fitnesses of all the snakes in the Swedish population, how would the mean fitness of the snakes in the Swedish population differ before and after the introduction of the snakes from the outside population?
b) This type of experiment, where members of an outbred populations are introduced to an inbred population as mating partners, is sometimes called a “genetic rescue”. How might measuring the average heterozygosity at a number of loci in the Swedish snake population allow you to test whether the introduced snakes had actually bred successfully with the inbred Swedish snakes?
c) Is there evidence that random genetic drift in the inbred Swedish population had led to a decline in mean fitness that was sufficient to cause the extinction of the population? Here, I am asking about the Swedish population before the outbred snakes were introduced. What is the evidence for a decline in mean fitness, if you believe this happened?
Ответ:
Correct B). Carbon dioxide and methane
Greenhouse gases are those gas which traps the heat of the atmosphere, it absorbs the heat energy and allows the less heat to escape back to space.
The greenhouse gases found naturally in the earth's atmosphere are carbon dioxide, water vapor, methane, and nitrous oxide, while the man made greenhouse gases are Chlorofluorocarbons, hydrofluorocarbons etc.
The concentration of these both the greenhouse gases are increasing rapidly due to industrialization and overuse of fossil fuel such as coal, petroleum etc which ultimately leads to global warming.
