UNIT 7
CRITICAL THINKING QUESTIONS
REVIEW QUESTIONS
1. How is bioengineering different from biology?
Bioengineering is based around the study of life around the Earth and using your
knowledge in biology to engineer for it.
2. Explain the separation and purification process.
Separation is when you take a substance and separate it from another substance. The
purification process is when you bring a substance to its base constituents.
3. Why are bioengineers interested in viruses?
Bioengineers are interested in viruses because of the potential they sustain through
modification, and maybe they can take those qualities and mimic it into a cure for people's
sickness.
4. How do viruses reproduce?
The virus attaches to a host cell and then implants it with its genetic information. At that
point it takes over the cell and reproduces through the cell enzymes, then it releases and
breaks out of the host cell. The particles that come from it can also produce new virus
particles.
5. Why are viruses so difficult to combat?
Viruses are so difficult to fight because they can take over someone's body and reproduce
rapidly. There are also not many ways to treat some viruses.
