Explanation:
The length of the sperm in a few species is much larger or giant than the size of the animal-like observed in the <em>Drosophila bifurca.
</em>
In this fruit-fly, the tails of the sperm are too long which could be accounted for many reasons:
1. The sexual selection prefers the long tails over the small tail.
2. The large sperms can displace the small sperms in the female reproductive organ.
3. The female reproductive organ increases the promiscuity of the large sperms that is favour the large sperms over the small sperms.
0.3 Because 5-2=3 so that should be correct let me know if that helps! :)
The inducer deactivates the repressor protein. This allows
the gene which the repressor protein suppresses, to be actively transcribed.
When the inducer fits in its allosteric site on the repressor protein, the repressor changes conformation and is not able
to bind the operator site of the operon.
