Question

which one of the culture medium is most suitable medium for culture of drosophila melanogaster and why.
1. moist bread
2.agar-agar
3.ripe banana
4.cow dung

Answer 1

3- ripe banana because other tropical fruits have not been tested as a suitable medium to complement banana medium. There are two main objectives of carrying out this study. The first aim was to test the effect of different culture media on the hatching and growth of Drosophila melanogaster. Secondly, the effect of different culture media on collecting and hatching wild-caught Drosophila species were examined. The combination of objectives of this study is to investigate and develop a more suitable culture medium for culturing D. melanogaster. In this study, five different types of single fruit culture media and another five different types of culture media with a mixture of fruits and/or other ingredients were formulated and prepared. Banana medium was prepared as standard medium (positive control), and plain agar was used as negative control medium. The different types of media comprised different nutritional values and sugar contents.

Answer 2

Answer: Ripe banana

Explanation:

Ripe banana can be the best suitable substrate for the growth of Dorsophila melanogaster. This is a very common type of fruit fly which is used for biological research system.

Moist bread can be used as a substrate for the growth of molds. It favors the growth of molds on it.

Agar-agar can be used for the growth of the bacterial culture. Cow dung can be used as a substrate for halomonas species.

Ripe banana can be the best for the growth of Drosphila melanogaster.
