question 10 (2.5 points)
the plasma membrane
controls the contents of the cell
is composed mostly of cholesterol
is permeable to ions and polar molecules
is free of proteins
is rigid and impermeable
question 11 (2.5 points)
archaea were given their own separate domain because they are
considered a type of bacteria
- The plasma membrane is a selectively permeable barrier that controls what enters and exits the cell, thus controlling the contents of the cell. It is mainly composed of phospholipids (not mostly cholesterol), has proteins embedded in it (not free of proteins), and is semi - permeable (not impermeable to all ions and polar molecules, but has specific transport mechanisms).
- Archaea were given their own domain because they have distinct molecular characteristics (such as unique cell wall and membrane compositions, and different ribosomal RNA sequences) that set them apart from bacteria.

Question 10: controls the contents of the cell
Question 11: (No correct option provided in the given choices as the proper reason is about their distinct molecular features, but if we assume the options are wrong - formulated, perhaps the intended answer is that they are different from bacteria in fundamental ways, but the given options for Question 11 are incorrect as stated)
