Any method above works well contains only a single kind of organism, where as a culture contains more than one kind of organism. d. Mixed; pure 10. A a. Mixed; aseptic bAseptic; pure c. Pure;, mixedExplanation / Answer
1. option first is correct.
More X indicates more resolution and magnification.
Here 100X clear resolution then other available options.
2. option a is correct.
electron microscope use electrons for production of images which is more clear
as compared to light microscope.
the magnification and resolution of electron microscope is higher than light microscope.
3. option A is correct
the magnification is the power to increase the visualising size of an image.
resolution is a power to separate to purse with a good distance in image.
4.
option A is correct
light microscope have a condenser region on which light become converge and then transferred to the object.
