IBDP Biology Question Analysis Topic: Biology - Short Questions
Exam Questions:
1) Write the importance of MOET (multiple ovulation and embryo transfer).
2) Name two commonly used bioreactors. State the importance of using a bioreactor.
Answers:
For IBDP Biology, you should know:
1(a) In this process, a cow is given hormones with an FSH-like activity. Through this, follicular maturation and super-ovulation occurs, producing 6-8 eggs per cycle instead of one.
(b) Problems of normal mating is thus avoided, and crossing between mature males and females have a high success rate.
(c) The production of hybrids with desired qualities is ensured.
(d) Such a process is highly economical, since a small amount of male cow semen can inseminate several cattle.
2) Two commonly used bio-reactors:
- simple stirred tank bioreactor
- sparged stirred tank bioreactor
Importance:
- a large amount of cultures (100 - 1000 L) can be processed.
- optimal conditions for getting the desired product is provided, such as temperature, pH and substrates.
Work hard for your IBDP Biology examination!
