EOC Biology Cell Test

Both euglena and cyanobacteria are photosynthetic unicellular organisms found in pond water. The feature that distinguishes euglena from cyanobacteria is the —

• ability to maintain homeostasis
• presence of ribosomes
• ability to reproduce
•  presence of a nuclear membrane

In the early 1980s scientists were able to produce two biomolecules by splicing a human gene into the bacterium E. coli to make recombinant human insulin and growth hormone. Which statement best explains why this experiment was successful?

• Human cells are eukaryotic, and E. coli cells are prokaryotic.

• All living organisms share the same genome.

• The genes for all organisms are composed of the same building blocks.

• The human body contains many types of bacteria, including E. coli.

What is the definition of  Selective Permeability?

• The movement of materials across the cell membrane that requires NO ENERGY from the cell.
  
• The movement of materials through (or across) the cell membrane
  
• The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.
• The movement of molecules from an area of high concentration to a area of low concentration
