As part of their research on cell reproduction, ms. kelly's biology class designed various experiments to determine the best conditions for budding, or asexual reproduction, in common yeast cells. one group of students placed yeast in a test tube with warm water and table sugar as a source of food. to best observe and count the yeast cells budding, the students should use a

The correct answer would be - light microscope.

Explanation:

Yeast cells are microscopic organisms and can only be studied in microscope only. Any researcher or student has to use the microscope for the study of the yeast and its asexual reproduction condition.

The group of students can use the light microscope for counting the yeast cell budding. The light microscope is an instrument that helps in the study of the organism that is not visible to the naked eyes.  

Thus, the correct answer would be - light microscope.
