EOC Review

The picture shows a 3-D model of a virus called a bateriophage. Bacteriophages can attacks bacteria such as E. coli.

How are the bacteria (E. coli) and virus (bacteriophage) alike?

• They have similar Genomes

• They reproduce with mitosis

• They produce or stimulate anitbodies

• Membrane-bound organelles are absent

Draw a unicellular Animal.

Label the membrane-bound organelle that contains DNA.

Some protein channels in a cell membrane can use energy to change their shape to allow certain molecules to pass through the membrane. This is an example of...
