Duckweed as a nutrient thief and bioremediator Hypothesis: This experiment will evaluate duckweed and its ability to remove nutrients and toxins from water sources. Thus‚ duckweed will kill the organisms that require similar nutrients‚ yet aid the organisms that would otherwise die to toxins. Specifically‚ if one was to place Elodea plants in a tank with duckweed‚ then the Elodea will die due to the lack of nutrients from the duckweed having used the nutrients for its own benefits.

There has been some debate when and whether Vaalbara existed. An Archaean-Palaeoproterozoic (2.8–2.1 Ga) link between South Africa and Western Australia was first proposed by Button 1976. He found a wide range of similarities between the Transvaal Basin in South Africa and the Hamersley Basin in Australia. Button‚ however‚ placed Madagascar between Africa and Australia and concluded that Gondwana must have had a long stable tectonic history.[2] Similarly‚ in the reconstruction of Rogers 1993‚ 1996
