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
Answer:
Temperature
Explanation:
An experiment has an independent variable which is a factor changed during the experiment. Effect of changes in the independent variable on the dependent variable is seen during the experiment.
According to the question, the experiment was set to observe the effect of temperature on bacterial growth. The bacterial population was exposed to different temperatures. Since the temperature was changed to observe its effect on bacteria growth, the temperature is the independent variable here.

I'm not sure about number 1 or number 6, but I know that 3 is nucleic acid and 5 is solution.
The type of noncoding dna that comprises the largest portion of multicellular eukaryotic genomes would be transposons. It <span>is a small piece of DNA that inserts itself into another place in the genome. Hope this answers the question. Have a nice day.</span>
