Answer- A nocturnal pollinator
The comet orchid is most likely pollinated by a nocturnal
pollinator because of the nightly aromatic scent emitted by its nectar. This makes it possible for a nocturnal pollinator to
detect,visit and pollinate it at <span>night. The lack of scent during daylight hours makes it unlikely for a diurnal
pollinator to visit it.</span>
The answer is; C
This phenomenon is called bottleneck effect and drastically affects small populations in comparison to large ones. The mudslide wipes off most of the population B at the base of the hill base. Due to their small population, a large proportion of the population is lost and the pollution loses most of its alleles leaving a small proportion to continue the population succession. Its diversity is hence reduced as it repopulates. The larger population is not greatly affected because it covers much of the hillside.
Invasive aquatic species, like the zebra mussel, attach themselves to the hull of ships and are blasted off when the ships release their ballast after unloading cargo.
