4. Imagine an animal cell that does not have a cell membrane. One problem for this cell would be that its internal parts would no longer be separated from the external environment. What would another problem be?
a. The cell would live, but not a have a stable structure.
b. The cell would die because it would not be able to control what goes into and out of the cell
c. The cell would live, but would not be able to store water, nutrients, and waste

Answer 12

Ok....
1. A ribosome binds the mRNA and tRNA to synthesize polypeptides and proteins. So, a malfunctioning ribosome might cause...

2. prokaryotes are simple unicellular organisms, far less complex than eukaryotes. Additionally, they contain tails (there is a biological name for this tail that will help you answer this question).
