Answer:
See the answer below
Explanation:
The light microscope is able to produce images in their natural color because photons of visible light are utilized as a light source and color is a function of light. Both transmission and scanning electron microscopes are not able to produce images in their natural colors because they utilize beams of electrons to image specimens. <em>They produce grayscale images instead because the regions of the specimen where electrons pass through are usually white while other regions remain black.</em>
Antibiotic resistance happens naturally due to genetic mutation through random selection, however, genetic drift occurs on purpose and tests which genes are stronger and should continue to be passed on to future generations. In most cases, genetic drift is needed and antibiotic resistance isn’t.
Answer:
I think #2 is a coastal marsh

#3 is either pond or ocean
Explanation:
To measure cross-linking amino acids in a collagen hydrolyzate using a conventional amino acid analyzer with ninhydrin detection, the bulk amino acids must be largely removed to avoid plugging the reaction coil. Tissue is thoroughly reacted with sodium borohydride to convert all intermediate cross-linking residues to their reduced, acid-stable forms. More vigorous reduction conditions may be used than when preparing profiles of tritium-labeled cross-links using NaB3H4<span> and direct amino acid analysis. </span>
Answer:
B. False
Explanation:
Orthologs are genes that find their origin in vertical descent,, paralogous on the other hand, are genes that are related via duplication events. <em>In the case of human hemoglobin, their genes originated by duplication from an common ancestral globin gen, therefore they are paralogous.</em>
