Hello students, in this question we have been asked about the results agreeing with the expected results and how can you distinguish between motility from brownian movement.
00:15
So firstly, when we compare the results, it depends on the specific experiment conducted and the expected results.
00:27
If the observed result match the expected results, then we can say that the experiment was successful.
00:43
Next, we have the distinguishing factor between motility and brownian movement.
00:49
Motile organisms show directional movement while brownian movement is random and non -directional.
01:07
By observing the pattern of movement, we can distinguish between the next, we have comparing a face contrast microscopy with brightfield.
01:23
So, face contrast, it provides better contrast and allows for visualization of transparent or colorless specimens without staining.
01:40
Whereas, brightfield microscopy requires staining.
01:47
Staining is an important step in brightfield microscope.
01:55
So, staining is required.
01:57
So, this is the comparison and it also has lower contrast as well.
02:05
So, this is the difference...
