Answer:
A whale bleeding from a cut.
Explanation:
Shivering in the cold, breathing hard during exercise, and sweating because it's hot are ways the body is working to maintain good functioning and to keep the body alive. Bleeding from a cut is not an example of this.
Answer:
This is phenylacetic acid, also known as phenylethanoic acid.
Explanation:
It is a carboxylic acid so it ends in the suffix -oic. The carboxylic acid has two carbons so it is called ethanoic acid. It is attached to a phenyl group so it that makes it phenylethanoic acid. Ethanoic acid is also known as acetic acid, hence another name is phenylacetic acid. Carboxylic acids have the highest priority in IUPAC naming after cations so the parent chain is the carboxylic acid part.
The _HIGHER__ vapor pressure at high altitudes causes a liquid to boil at a _LOWER___ temperature.
Explanation:
Vapor pressure is the pressure applied by the molecule of a liquid at the surface of the liquid as it transitions into a gaseous phase. When the vapor pressure exceeds the atmospheric pressure, this is when the liquid begins to boil. Therefore when the atmospheric pressure is low, then the liquid will boil at lower temperatures, because the vapor pressure of the liquid will overcome the atmospheric pressure at lower temperatures.
Answer:
Nitrogen emissions such as ammonia, nitrogen oxide and nitrous oxides contribute to particulate matter and acid rain. Nitrous oxide is a particularly potent greenhouse gas as it is over 300 times more effective at trapping heat in the atmosphere than carbon dioxide.
