Answer:Increase in ambient global temperatures.
Recyling energy to be used again
Regulation of oxygen and carbon dioxide levels
An increase of erosion and siltation along waterways
Explanation:
Conservational biologists think about the preservation of ecosystem by maintaining the environment in a human control way.
Increase in ambient global temperatures.: The humans must prevent the increase in global temperature worldwide by preventing the rise of greenhouse gases which can lead to global warming worldwide.
Recyling energy to be used again: The sources of energy like wood, waste water can be recycled again for reutilization.
Regulation of oxygen and carbon dioxide levels.: The oxygen and carbon dioxide levels must be regulated. As oxygen is the basic requirement for respiration. The increase in carbon dioxide levels due to human activities is likely to cause respiratory diseases and health hazards in living beings.
An increase of erosion and siltation along waterways.: The erosion and siltation will likely to deposit nutrients and debris which may either contaminate the waterway or may cause eutrophication.
The classic signs of the cushing syndrome include fat accumulation behind the shoulders, known as a buffalo hump, and a round "moon-shaped" face. Cushing's syndrome is a hormonal disorder caused by prolonged exposure of the body's tissue to high levels of the hormone cortisol. The symptoms of this disorder includes; weight gain, obesity, fatty deposits especially in the midsection, the face, and between the shoulders and the upper back.
I think it’s B.heating and cooling it is used over 40%
Because we know that 15% of the population does not have the allele we can assume that at least 85% of the population has at least on copy of the dominant allele.
