The Correct answer is A.
As snow becomes compressed , air between the flakes gets trapped. The process involving trapping of air occurs during burial of snow layers and is generally not complete until the bubbles are about 60 meters or more below the surface.
Once the bubbles have formed, they act as the time capsules of the atmosphere when they were trapped. By extracting the air from the bubble in ice cores, changes in the past can be studied .
Studies of these changes show the dramatic increase of what are called greenhouse gases such as carbon dioxide, caused by human use of fossil fuels, as well as natural changes that accompany glacial climate
C. The number of protons and neutrons.
Answer:
Explanation:
Cyanoacrylate or super glue fuming is used to develop latent fingerprints and make them visible.Fingerprint powders, however, adhere to the sweat and therefore the powders have a difficult time adhering to only the amino acids, proteins and fatty acids.

Answer:
The correct description of the relation is reaction velocity always increases with an increase in temperature (option B).
Explanation:
A chemical reaction can be affected by a variety of factors, including the concentration of reactants, pressure and temperature. In the case of temperature, <u>the reaction rate increases depending on the temperature increase</u>.
In a chemical reaction, a temperature -or heat - elevation results in an increase in the speed of motion of each component's particles, while increasing energy and effective shock between them.
<em>
Reaction → heat → increased energy → greater effective shocks of particles</em>.
As a result of this, the relationship between reaction velocity and temperature is that at a higher temperature makes a reaction faster.
