After performing an endospore stain of bacillus cereus, the cells all appear as pink rods with clear spaces inside them. what is the best explanation for this observation?

Pick color shows there was no endospore rather vegetative cells

Explanation:

Endospores are structures normally formed by gram positive to withstand harsh condition such as lack of nutrients.

Endospore staining used to test the presence of endospore in a bacterial sample.

Just like Gram staining, endospore staining uses two stains.

The primary stain being the Malachite green and Safranin is the counter stain.

Endospores will take up the primary color green and resist the counter stain whereas vegetative cells will stain pink

Therefore the pick color shows presence of vegetative forms of the Bacillus cereus and no endospore.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
