A large assortment of plant dispersal mechanisms.
Explanation:
Pretty much everything can be explained about Australia, as to where it was in the past, with which other large landmasses it was connected, its flora, its isolation from the other continents... One thing that still needs explaining is the large assortment of plant dispersal mechanisms, which is not typical for well established islands.
The reason as to why this is weird and hard to explain is because the well established islands have flora that is well adapted to their living conditions, and also it lacks competition from outside. In other words, they rule the place. The plants in Australia though exhibit dispersal mechanisms that are typical for the plants of the continental masses that are connected, so it causes big problem in explaining it.
The correct answer of the given question above would be option A. The statement that is true of modern cell theory is that, a<span>s technology improves, so will our understanding of cells. More improvement in the technology would lead to more discoveries and also would correct other information that has been done in the past for improvement. Hope this answer helps.</span>
The impact of the meteorite marks what is known as the Cretaceous-Tertiary or K-T boundary. Geologists across the world have noted a thin layer of soil that marks this boundary. It is rich in Iridium, an element that is extremely rare on earth but very common in meteorites. The layer was formed as the vaporized material from the impact dispersed in the atmosphere and was eventually deposited across the globe. <span />
