D) Moist
Answer:
In acid-fast staining, carbon fuchsin is used as a primary stain which dissolves the mycolic acid present in the cell wall of <em>Mycobacterium smegmatis </em>and penetrates through it which results in staining <em>Mycobacterium</em> red.
Staphylococcus aureus cell wall does not contain mycolic acid so carbon fuchsin does not penetrate its cell wall, therefore, it becomes colorless after destaining with acid alcohol.
After destaining step methylene blue is added to stain non-acid-fast bacteria blue. So if I mistakenly forgot to use methylene blue during the procedure <em>Mycobacterium smegmatis</em> will appear red due to carbon fuchsin present in their cell wall and S<em>taphylococcus aureus</em> will appear colorless because it is destained.
Answer:
The correct answer is b. All round seeds
Explanation:
If an RR plant is crossed with an rr plant than all the phenotype will produce round seed and the frequency of the Round seed plant to wrinkled seed plant would be 4:0.
R R
r Rr Rr
r Rr Rr
So all the phenotypes will be heterozygous dominant for the round seed which means that all phenotypes will have a single dominant allele for round seed which is enough to express round seeds in the phenotypes.
Tectonic plates are the result of the mantle cooling on the surface. At plate boundaries or "zones" occure, there are different reactions along the edges of them. Divergent is when two plates move away from one another allowing fresh molten rock to flow to the surface. This results in a volcano. Covergent boundaries are when plates come together, resulting in mountain ranges. Transforming boundaries are when they slide up against each other causing earthquakes. More examples of proof of plate tectonics is the changing of Pangea into the world as we know it and subduction zones that reveal fossils that were deeply buried under layers of earth.
