fraction, and the other tube contains the mitochondrial inner membrane fraction, but the tubes are not labeled. When you analyze the macromolecule composition of the samples, you are confident that the second tube contains the mitochondrial fraction, because the sample has
A) a higher ratio of cholesterol to phospholipids.B) a higher protein to lipid ratio.C) a lower protein to lipid ratio.D) more carbohydrate in glycoproteins.E) more GPI-anchored proteins.

Answer:

B) a higher protein to lipid ratio.

Explanation:

The cell membrane of eukaryotes is known to be a phospholipid bilayer with embedded proteins.  This implies that the first tube will contain a higher amount of lipids.

The membrane of the mitochondria is slightly different from the cell membrane in which its protein to lipid ratio is higher, containing a large number of integral proteins.

The correct answer is rapids and waterfalls.  

Rapids refers to the segments of streams with extensively vigorous currents, various obstacles, and steps in their streambeds. A waterfall refers to a vertical drop in a stream bed. Both are the locations of vigorous erosion.  

The rapids are generally produced where the resilient bedrock limits a stream to a narrow channel and forces an enhancement in the velocity of water.  

On the other hand, waterfalls are produced where the fast-flowing water negotiates a geologic contact amid the more resilient and less resistant layers of rock, or through a fault, which has analogized distinct kinds of rocks. Or it can be said that waterfalls usually produce at the end of a series of rapids.
