Hello. You did not enter the text to which these questions refer, which makes it impossible for them to be answered. However, I will try to help you in the best possible way.
It is only possible to answer your questions in a specific way by reading the experiment, however, I can inform you that formites are objects that allow the colonization and growth of microorganisms that can be major causes of diseases. Among these microorganisms are bacteria, fungi and viruses of the most varied species. Among these microorganisms, both fungi and non-demanding bacteria can grow in a nutrient agar culture medium. This is because this is a very simple culture medium where bacteria that do not need specific nutrients can grow and where most fungi can grow too. However, it is impossible for viruses to grow in this type of culture medium or in any culture medium, since viruses only develop inside a host's organism. Bacteria known as fastidious would also not grow in this type of culture medium, since they only grow with the presence of very specific nutrients.
The SWELLING AND BURSTING of animal cells when water enters is called cytolysis. This happens when a cell is placed in a hypotonic<span> solution. pulls away from the cell wall is called plasmolysis. It happens when a plant cell is placed into</span>hypertonic<span> solution. i got this from google if it helps

Asexual reproduce will result in genetically identical offspring
Answer:
Planarian stem cells are known as neoblasts. The nature of the neoblasts and the processes that occur as regeneration is activated and carried out are still being investigated.
Explanation:
Humans also have stem cells, but to a more limited extent than planarians. The cells have a characteristic known as potency and are classified as follows:
Totipotent stem cells can produce every type of cell in the body plus the cells of the placenta.
Pluripotent cells can produce every type of cell in the body but not the cells of the placenta.
Multipotent cells can produce several types of specialized cells.
Unipotent cells can produce only one type of specialized cell.
The stem cells in planarians are pluripotent (or at least the ones that have been studied are). There are so many of them throughout the body that even a small piece of a planarian contains the cells.
