Answer:
Anomalous expansion
Explanation:
Anomalous expansion of water is the abnormal way water expands when exposed to low temperature.
At 4 degree Celsius , the density at the top layer is usually at the Maximum which makes the water sinks down and then the water in the lower layer rises up.
When the temperature drops below 4 degree Celsius, the water molecules at the top then freezes leaving the denser molecules at the bottom which doesn’t freeze as a result of their high density.
This way, organisms can survive in the water due to the lower layer not freezing.
Explanation:
Animals and plants need to get rid of carbon dioxide (c02), this process is called respiration. Respiration happens when the plant/animal breaths in air and releases it as carbon, carbon then moves from fossil fuels to the atmosphere where they are burned. When humans burn fossil fuels to power cities, power plants, cars, and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.
Answer: a.The study is funded by a group with a financial interest in the outcome.
Explanation:
Junk science is a term that is used to describe scientific research or data that is false and fraudulent and is usually presented in order for the people behind it to be able to push an agenda or assertion.
If a study is funded by a group with a financial interest in the outcome, the research could end up being junk science as the backs might persuade the researchers to manipulate the data in such a way that it would favor them.
For instance, a Big Tobacco funded research into lung cancer finding that smoking does not contribute as much as previously thought to lung cancer
