What would be seen if we stained endospore samples after one week of incubation, instead of staining before incubation? Would the cells be the same color and size or would that change? and why could it change? Also what is the appearance of stained endospores by light microscopy?
Homework Answers
after incubation some endospores would germinate into viable spores as endospores would get favourable condition. in these favourable condition, spores would convert into vegetative cells.
Appearance would change of endospores if we stain by Schaeffer-Fulton staining technique it will become pink/reddish in color. if there are remaining endospores would stained into green color.
size would also change of endospore as changing into viable spores and spores are changing into vegetative cells.

We have seen that (at least for the above example) that we can treat the image of one lens as the object for the next. Also, the overall magnification can be found by combining the individual magnifications. So let's investigate what happens when this first image falls at various positions relative to the second lens and what different types of lenses do to the final image. Begin by setting up the optical bench as follows Set...

In order to measure the rate of this reaction, we utilized the fact that starch - in the presence of iodine has a distinct dark blue color while the conversion of starch to its monomer leads to a more transparent/amber colored solution. While you used a simple visual analysis to verify the conversion, it is also possible to quantify the change in (starch) using a spectrophotometer. 1. Why/how was a spectrophotometer used for this purpose? EXPLAIN what this machine does...
