It is false that as <span>you watch an airplane fly above you, the angle of elevation to the airplane gets closer to 0° as the airplane approaches the point directly overhead.
As a matter of fact, it gets closer to 90</span>°. When the plane is far away, then it is closer to 0. But since it is overhead, it is almost exactly 90°.
The decarboxylation reaction involves the removal and replacement of a carboxyl group with hydrogen.
<h3>What is a decarboxylation reaction?</h3>
A decarboxylation reaction is one in which the carboxyl group in a carboxylic acid is replaced with hydrogen.
In living organisms, decarboxylation reactions are catalyzed by enzymes called decarboxylases or carboxy-lyases.
The decarboxylation of beta-carbonyl esters proceeds through a cyclic transition state giving an enol intermediate which then tautomerises to the carbonyl.
Therefore, a decarboxylation reaction involves the removal and replacement of a carboxyl group with hydrogen.

The answer is C since the higher up you go the colder it gets which is why Linda will experience colder climates.
Answer:
If it points the other way, the fields subtract, for a lower energy, and so the magnet prefers to turn to point in this way. Magnets in uniform fields feel torques which make them turn around if they are not pointing in the right direction, but there is no net force making the magnet want to levitate.
Explanation:
Fire extinguishers are typically red. Goes along with the red fire trucks and red being a color of emergency. While there isn't any standard, if we decided to change the colors of the fire extinguisher, people would be very confused and given the context, it could cost people's lives, so I'm thinking red will be the color of fire extinguishers for a while to come.
