Answer:
541 million years ago with the Cambrian explosion, an extraordinary diversification of marine animals, and ended about 252 million years ago with the end-Permian extinction, the greatest extinction event in Earth history.

Explanation:
The first famous natural scientist to determine how plants change with altitude on tall mountains was Alexander Von Humboldt and Aime Bonpland when climbing some very high volcanoes in South America like Chimborazo at well ove 20,000 feet high and they observed that different plants grow at different altitudes as altitude increases so that as the mountain was ascended the new environments of temperature, moisture,etc would become abiotic for the lower plants but acceptable for the higher elevation plants. In these cases in South America, the lower elevations had very warm temperatures and high humidity so would grow tropical plants with probably large leaves like palm trees etc. On the other hand at high elevations the temperature would be significantly decreased and probably humidity decreased too so only rugged plants like say lichens could grow. At intermediate elevations, most likely say pine trees could grow as I know they do at moderate elevations in Honduras for example.
Due to its short life cycle this fly can easily multiply if its population is not controlled. <span>The house fly is known to carry more than 100 diseases including tuberculosis and cholera</span>
<span>An amphibian that lacks lungs and breathes entirely through its skin would have to be smaller than an amphibian with lungs so that the small oxygen intake correlates with
the small surface area of the amphibian. This would then allow it to breath efficiently.</span>
<span>Reproduction (or procreation) is the biological process by which new "offspring" individual organisms are produced from their "parents". Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction. The known methods of reproduction are broadly grouped into two main types: sexual and asexual.
In asexual reproduction, an individual can reproduce without involvement with another individual of that species. The division of a bacterial cell into two daughter cells is an example of asexual reproduction. Asexual reproduction is not, however, limited to single-celled organisms. Most plants have the ability to reproduce asexually and the ant species Mycocepurus smithii is thought to reproduce entirely by asexual means.
Sexual reproduction typically requires the involvement of two individuals or gametes, one each from opposite type of sex. The propagation of organisms can also occur through cloning.
