Agroup of scientists build a net along a section of the river to separate a group of foreign fish species from the rest of the river. they wish to determine
whether their experiment is a closed system by placing a colored dye in the fish's habitat and observing whether the dye escapes from the enclosure.
could this experiment determine whether the system is closed or not? justify your answer based on the definition of a closed system.

This experiment would be unable to determine whether the system is closed or not. This is because the scientists have used a net to separate the sections of a river. Nets have holes in them through which the dye would easily be able to pass. The net would not be able to hold water. Hence, this experiment is not appropriate.

This test will also not be able to determine whether energy flows between the two systems or not.

The experiment could not determine whether the system is closed or not.

Explanation:

The net doesn't hold water. But it is a good part of the experiment for testing whether the system is closed or not with the dye (matter). The problem is that the experiment doesn't test the flow of the energy. And that's an important part to see whether the system is closed or not.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest

i won't lie i don't know so go online and ask google thats what i do
