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 limitations in designing and building an eco-friendly home in Illinois will be climate constraints and social limitations.
<h3>What are eco-friendly homes?</h3>
Eco-friendly homes are homes which are designed such that they do not pose any danger to the envrionment.
Eco-friendly homes are compatible with the environment and make use of available environmental resources to design an environmental-friendly home.
The limitations in designing an eco-friendly home in Illinois will be:
- Climate constraints - due to hot climatic conditions
- Social constraints - due to its dense population
Therefore, the limitations in designing an eco-friendly home in Illinois will be climate constraints and social limitations.

Answer: if there were no decomposers in an ecosystem then, wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem.

Magnetic Striping<span>
</span><span>The confirmation of the theory of plate tectonics relies on key insights and scientific experimentation. One of these is the knowledge of the magnetic properties of ocean crust.</span><span>Early in the 20th century, Bernard Brunhes in France and Motonari Matuyama in Japan recognized that rocks generally belong to two groups based on their magnetic properties. One group known as normal polarity has within its mineral composition a polarity similar to the Earth’s magnetic north. The magnetic properties of the other group, called reversed polarity, is the opposite of the Earth’s present day magnetic field. The reason, tiny grains of magnetite found within the volcanic basalt that make up the ocean floor behave like little magnets. These grains of magnetite can align themselves with orientation of the Earth’s magnetic field. How? As magma cools, it locks in a recording of the Earth’s magnetic orientation or polarity at the time of fooling. </span><span>The Earth’s magnetic field is similar to the field generated by a bar magnet with its north end nearly aligned with the geographic North Pole. Yet the Earth’s field is the result of a more complex, dynamic process: the rotation of the planet’s fluid iron rich core. Scientists have known for centuries that the Earth’s magnetic field is dynamic and evolving. The magnetic field drifts slowly westward at a rate of 0.2 degrees per year. </span><span>However, over tens of thousands of years, this field undergoes far more dramatic changes known as magnetic reversals. During this reversal, south becomes north and north south apparently in a geological blink of an eye – perhaps over a period of a few thousands years. What these reversals recorded were stripes on seafloor maps-- stripes of alternating normal and reversed polarities of ocean crust. These “stripes” formed the pattern known as magnetic striping.</span><span>The ocean floor had a story to tell. That story would unfold in the work of three scientists. In 1962, two British scientists, Frederick Vine and Drummond Mathews, and Canadian geologist Lawrence Morley working independently suspected that this pattern was no accident. They hypothesized that the magnetic striping was produced from the generation of magma at mid-ocean ridges during alternating periods of normal and reversed magnetism by the <span>magnetic reversals </span>of the Earth’s magnetic field. </span>
