Answer:
They accurately compare the current atmosphere with the previous one, by assessing the amount of atmospheric gases present today, with the amount of atmospheric gases trapped in ice cores that they believe are millennial, that is, they have existed for thousands of years ago.
Explanation:
As we know, it is difficult to compare current characteristics of the planet earth with characteristics that the planet had in the past, thousands of years ago. This is because the ancient characteristics on earth are not fully available to be analyzed, since most of them have been modified over time.
To do this, scientists need to find factors that may have existed thousands of years ago and assess whether these factors have any account of the characteristics of the earth. In the case of atmospheric characteristics, it is common for scientists to compare the current atmosphere with the atmosphere of thousands of years ago, with the assessment of the amount of atmospheric gases trapped in ancient ice cores, with the amount of atmospheric gases present in the atmosphere today.

The three chromosomal aberration:
1.) Inversion - breakage of chromosome in two places , the other piece of DNA is re- inserted into the chromosome.
2.) Translocation - the one piece breaks off and attaches to another chromosome.
3.) Deletion - the loss of segment of chromosome.

Answer:
Glycerol and fatty acids are the basic building blocks of fats (lipids).
Explanation:
Answer:Cellular Respiration
Explanation:
Cellular respiration is the process by which cells produce energy, and is broken down into three more steps: glycolysis, Kreb’s cycle, and electron transport chain. Glycolysis requires glucose, two ATP, and NAD+, and two ADP, and produces two pyruvate, four ATPs, two NADH, and two H2O. The Kreb’s Chcle and thus the downstream electron transport chain require acetyl-CoA, one ADP, three NAD+, and one FAD, but pyruvate oxidation needs to happen prior to the Kreb’s Cycle, thus this is where the Oxygen is used and produced into two CO2.
