GCSE Biology Question Analysis Topic: Biology - Short Questions
Exam Questions:
1) Describe the mutual relationship between fig tree and wasp and comment on the phenomenon that operates in their relationship.
2) Explain the significant role of the gene nucleopolyhedrovirus in an ecological sensitive area.
3) Why is pedigree analysis done in the study of human genetics? State the conclusions that can be drawn from it.
Answers:
For GCSE Biology, you should know:
1) Mutualism is shown in the interaction between the fig tree and the wasp, which both deposits its eggs and pollinates the fig's infloresence. On the other hand, the fig allows the wasp's larva to feed on seeds in addition to shelter for oviposition.
2) Nucleopolyhedrovirus is used to kill insects like Heliothis and Spodoptera species in ESA to control their growth. Insects eat these viruses, which then enter the gut and subsequently destroy them.
3) Pedigree analysis is the study of a family's history about the inheritance of a specific trait over numerous generations. Because control crosses in people are impossible and because people have the capacity to live longer, pedigree analysis is used in the study of human genetics. A specific trait abnormality or disease can be traced using pedigree analysis.
