I am: A) DNA
DNA is double-stranded molecule which is often also it's most known feature. Perhaps less known (depends on who you ask) are facts that it also has thymine and not uracil (uracil is found in RNA). It has four nitrogen bases and it contains deoxyribose sugar (another hint that it's DNA and not RNA).
According to climate change scientists, the burning of fossil fuels (coal, oil, and the like) results in the releasing of carbon dioxide atoms into the atmosphere, which can cloud the atmosphere, obscuring sunlight, as well as deplete the ozone layer, resulting in an increase in global temperature. This change could potentially cause some cooler temperature-loving species to either migrate in search of cooler locations or possibly die out if they are unable to move (biosphere). It could also cause water levels in some areas to decrease due to evaporation, or increase due to the releasing of water into the oceans resulting from the melting of our polar ice caps (hydrosphere).
Hope that helped! =)
Answer:
the questionnaire is incomplete, the options are attached to the graph
correct answer c
Paine's experiment was performed when exrtaer the starfish that was considered a negative predator by feeding on a local mussel, what was expected is that by eliminating the starfish it proliferates but its consequence was that it began to displace other species When the mussels became a predator due to the alteration of the ecosystem, the balance was removed and now the species cannot coexist.
The products are all chemical compounds on the right side of the chemical equation.
