Scientists need to learn to make arguments based on evidence. That means they back up their statements with facts that support them. Prokaryotes and eukaryotes look very different. Please make an argument based on evidence that they should both be considered cells anyways.

All complex life on Earth is eukaryotic. All eukaryotic cells share a common ancestor that arose just once in four billion years of evolution. Prokaryotes show no tendency to evolve greater morphological complexity, despite their metabolic virtuosity. Here I argue that the eukaryotic cell originated in a unique prokaryotic endosymbiosis, a singular event that transformed the selection pressures acting on both host and endosymbiont.

The combination of massive bioenergetic expansion, release from genome-size constraints, and high mutation rate favored a protosexual cell cycle and the accumulation of eukaryotic traits. These factors explain the unique origin of eukaryotes, the absence of true evolutionary intermediates, and the evolution of sex in eukaryotes but not prokaryotes.

a
Y is a gas because it has a definite volume.

b
X is a liquid because it has a definite volume.

c
Y is a liquid because it fills up the entire container.

Imagine that you have just made a fresh apple pie. When you take it out of the oven, it is so hot, you can't even hold it in your hand; so you place it on the kitchen table. Now, several minutes later, you are able to cut a slice and eat it. The apple pie has cooled, the question now is, where has the heat gone? Select which of the following below is most likely to have occurred and provide a well developed, written explanation for your response using scientific principles learned in class.
