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).

r-ruslan [8.4K]

The preferred prey item would be frogs.

What is optimal foraging theory?

It is a theory in ecology that proposes that predating animals that get the most energy from minimal efforts are favored by natural selection.

In order words, selection forces prefer investing minimum energy in order to extract maximally available energy.

In this case, the heron needs to use the lowest time to harvest the maximum energy possible. Since all the preys offer the same amount of energy, the one that requires the lowest time would be preferable for the heron.

In other words, frogs would be the most preferable prey.
