Uracil is readily produced by the chemical degradation of cytosine so have thymine as the normal base makes detection and repair of appearing mutations more efficient
<u>Answer</u>:
The difference between systemic and pulmonary circulation is the Systemic circulation carries the blood between to the heart and body and the pulmonary circulation carries blood between the lungs and the heart.
<u>Explanation</u>:
Circulation of blood is of two types:
The systemic circulation and The pulmonary circulation.
The Systemic circulation carries the oxygenated blood from heart to the body through the arteries (aorta) and also carries back the deoxygenated blood from the body to the heart through veins (superior vena cava) and pulmonary circulation carries deoxygenated blood to the lungs from the heart and from the lungs to the heart.
In Pulmonary circulation the pulmonary artery is used to carry the deoxygenated blood to the lungs and the pulmonary vein is used to carry oxygenated blood to the heart from the lungs.
petrified fossils -> date sedimentary rocks, this will be more precise but Carbon 24 dating would probably a very reliable way of gathering information too
Answer:
Option (e).
Explanation:
Karl Woese was an biophysicist and microbiologist. He was known as the originator of rRNA sequences in 1967.
Karl determines the 16rRNA sequence by the technique pioneered by Woese. He breaks the prokaryotes into two groups and discovered the third domain of life.
Thus, the correct answer is option (e).
So the breakdown of lipids actually starts in the mouth. Your saliva has this little enzyme called lingual lipase, which breaks down these fats into something called diglycerides. These diglycyerides then make there way to the intestines, where they stimulate the pancreas to release lipase (another fat breaking enzyme!) and the pancreas to release bile. The bile and pancreatic juices both work together to break these diglycerides into fatty acids. It’s helpful to know some of the root words. Glycerol- the framework to which the fatty acids stick. Glyceride- think of this guy as several fatty acids stuck to a glycerol. Lipids- think fats, and their derivatives (our glyceride friends.) tri/di/mono- these are just number prefixes! Lipids are one glycerol molecule, and then either one, two, or three fatty acids attached, which is where you get mono(1)/di(2)/tri(3)glyceride from. I know this was long, but hopefully it helps!
