Answers
The explanations that provide support for continental drift theory are;
• Coal fields match up across continents
• Tropical plant fossils were found in Arctic areas
• Similar rock types are found across continents
• Evidence of glacier can be found in South Africa
Explanation
According to Alfred Lothar Wegener in his studies on the origin of continents and oceans, he outlines that the theory of continental drift can be supported by five evidences which are; the jigsaw fit of the continental alignment, geological fit, tectonic fit, glacial deposits and fossil evidence.
Answer:
<h2>Purity</h2><h2>Aromatic rings, peptide bonds, primary structure, secondary structure, and tertiary structure,</h2><h2>Nucleic acid,</h2><h2>260nm.</h2><h2 />
Explanation:
The A260/A280 ratio method estimates protein purity by measuring the absorbance maximum at 280nm caused by the amino acids aromatic rings, peptide bonds, primary structure, secondary structure, and tertiary structure. Since nucleic acid also absorbs in the UV range, we can correct for this contaminate by measuring the absorbance maximum at 260nm and using the following equation.
