B. One
because an independent variable is something you change. So in a scientific experiment you only change one thing. If you happen to change more than one thing then the test becomes unfair therefore you should repeat and make sure that only one thing is changed this time.
Answer: Carbon dioxide
Explanation:
The chemolithophs are the prokaryotes which uses inorganic matter in order to make organic materials for the other processes.
These organism get energy by the oxidation of the inorganic compounds. The organism such as human beings breaks down the organic compounds in order to get energy and nutritional building block.
The macro molecule used by the organism is carbon dioxide.
Answer:
Global warming is caused by the greenhouse effect caused by greenhouse gases, such as carbon dioxide, in the earth's lower atmosphere. A release of carbon dioxide into the atmosphere by carbon sources such as fossil fuel burning increases the greenhouse effect hence increased global warming. Another effect of higher carbon dioxide levels in the atmosphere is oceans acidification. The oceans will absorb more carbon dioxide and form more carbon acid hence lowering the pH of the waters. To alleviate this phenomenon, carbon sinks need to be protected such as forest because they sequester carbon dioxide from the atmosphere and store it as carbohydrates in their biomass.
