Answer:

Magnetic marbles will tend to attract each other.

Explanation:

Magnetic marbles are composed of ferromagnetic materials, which indicates that they function as a magnet and have the ability to attract other objects formed by ferromagnetic materials. In this case, we can say that the magnetic marbles attract each other and inside a jar containing magnetic marbles and common balls, the magnetic marbles will tend to attract and group together.

Megan observes four cells under a microscope and makes sketches of them as shown. Identify whether the cells are prokaryotic or
posledela
I cannot found the images of the microscopy anywhere. But I can explain how you can differentiate a procaryote from a eucaryote under a microscope.

The first difference between them is the size of the cell. eucaryotes are generally much bigger than procaryotes. Procaryotes are visible only at x100 objective, but eucaryotes are visible starting from the x10 zoom.

The second difference is the presence of a nucleus in eukaryotes and the absence of it in procaryotes.

The third difference is the presence of organelles in eukaryotes and the presence of a cell wall in procaryotes (only visible at electronic microscopy).
