If a scientist carried out a growth experiment on a prokaryote in media without a carbon source you would expect:

You place a cell without any osmotic homeostasis mechanisms into a solution of NaCl that is at a much higher concentration than that inside the cell. What is the likely effect on the cell structure?

Which of the following makeup of cellular membranes would be most likely best suited to COLD temperatures?

Consider the above data when filling in the blanks for the following questions.

A scientist measures the cell volume of S. aureus cells in various NaCl solutions. She measures three different cell types, shown by the black (1st), blue (2nd) and red bars (3rd). One cell type is “wild type” S. aureus. The other two cell types have each had a gene deleted. These genes each encode a different sodium transporter membrane protein.

Which data most likely represents the cell volume of the wild type S. aureus?

In those cells that have shrunk, the water has transferred from

Based on these data, the cell type represented by the blue bars (2^nd group)

Based on your knowledge about eukaryotic evolution, which these statements about the evolution and function of mitochondria is true?

Based on current evidence, one of the earliest events leading from the first eukaryotic common ancestor to the modern eukaryotic cell would be:

What aspect could you look at in a plant cell to determine if a chloroplast underwent secondary endosymbiosis?

Which of the following combinations is LEAST optimal for a prokaryotic cell with regards to the movement of molecules into, out of, and around the cell. 

One of the essential functions of the cell is transcription (RNA from DNA). Where is this carried out in eukaryotic cells and where is this carried out in prokaryotic cells?
