The photo shows a single-celled organism called a paramecium. How do single-celled organisms like this paramecium reproduce asexually?

Because a model would make the investigation easier to understand

The density of water is 1 g/cm cubed and in order for the pebble to sink its density has to be greater than the density of water and in order for the twig to float its density has to be less than the density of water

Man i dont know this answer
