Which of the following is an impact of increased ocean acidification as caused by global climate change?
Which of the following is an impact of increased ocean acidification as caused by global climate change? (Points : 1)
1. Question :
Which of the following is an impact of increased ocean acidification as caused by global climate change?
Student Answer: CORRECT Low pH seawater alters calcium carbonate concentrations which reduce the ability of many animals to build shells.
Increased acidification leads to expansion of coral reef populations.
Low pH seawater results in greater whale populations, which in turn skew biological ocean communities.
Increased acidification leads to lower water temperatures
thanks big help
Which statement is true regarding nuclear energy?
1. Nuclear power produces no greenhouse gasses and thus poses no environmental threats.
2. Nuclear plants rely on a massive industrial infrastructure using fossil fuels.
3. Due to strict safety regulations, nuclear power does not increase the threat of genetic mutation to nearby citizens.
4. Nuclear energy produces little to no waste and is thus preferable to other sources of energy.
5. None of the above statements are true regarding nuclear energy.
ANSWER: Nuclear plants rely on a massive industrial infrastructure using fossil fuels.
