Answer: e.All of the above are plausible. It is impossible to predict.
Explanation:
The long tongue of moth Xanthopan morgani is able to derive the nectar from the orchid. If through many generations the nectaries become shorter the moth may not be able to derive the nectar this may facilitate the other insect species to derive the nectar and pollination.
If more insect species will able to use the orchid for nectar then obviously the orchid is more likely to reproduce due to pollination. The nectaries may get even shorter that the nectar will readily available to the other species of insects. This may also interrupt the pollination of other species of orchids as Madagascar orchid is a source of nectar which will attract many pollinators also those were specific to the other orchid species.
All conditions are plausible. But several generations of evolution of the Madagascar orchid is required to be observed to predict the association of insects with the orchid.
Answer:

24
Explanation:
<em><u>Musca</u></em> <u><em>domestica</em></u> is the scientific name of an animal popularly known as Housefly. From the question, it is known that this organism has a haploid chromosome number of 6.
In a diploid chromosomes, the number of chromatids that will be present will be twice of that in haploid.
Since haploid (n) = 6, diploid (2n) will be; 2 × 6 = 12
Somatic cells on the other hand also exhibit diploid number of chromosomes, again it means we will have (2n) = 2 × 6 = 12
In metaphase cell, cells do make sure they complete the S'phase of the cell cycle before cellular division.Therefore, the DNA present in the chromatids in the S'phase actively engage in chromatids doubling, as a result, 24 chromatids (i.e 12 × 2= 24) exists in the metaphase cell.
Answer:
it is to do with something called angular moment. Gravity is the central force in the Universe, because it is the only one which has a significant pull over large distances.
