Students created note cards comparing characteristics of eukaryotic and prokaryotic cells. Which set of note cards most accurately compares these cells?

Given what we know about Eukaryotic and Prokaryotic cells, we can confirm that the note card labeled "F" is the one that best compares these two cell types.
Eukaryotic and Prokaryotic cells have many differences to discuss, the ones mentioned in note cards, however, are:
The presence of membranes surrounding organelle
The location of the DNA for each cell
Prokaryotic cells are cells that lack any organelle or nucleus. This is due to the absence of membranes, which are needed to maintain the structure of the organelle. Due to the lack of membranes and therefore of a nucleus, the DNA of these cells can be found floating in the cytoplasm. Table F is the only one that accurately represents these traits.
Eukaryotic cells, on the other hand, are those that do possess membranes. The presence of membranes allows the eukaryotic cells to have a nucleus that can contain their DNA. This cell type is that of most multicellular organisms, whist the prokaryotic are known most commonly as bacteria. Once again, table F is the one that best represents this data.

Which of the following is an example of an opposing signal? no examplthates given.   i would say, that traffic lights in a city at major intersections direct the flow of traffic in opposite directions so would be an example.also, stop signs on either side of the same street would be an example. at a train crossing, the light for allowing car traffic in opposite directions or not would be another example.
