Five sentences related to a topic are given in the question below. Four of them can be put together to form a meaningful and coherent short paragraph. Identify the odd one out. Choose its number as your answer and key it in.Remarkably, extreme events of diversification and extinction happen more frequently than a typical Gaussian distribution would predict.Throughout life's history on earth, biological diversity has gone through ebbs and flows – periods of rapid evolution and of dramatic extinctions.Evidence for these ecological changes is found throughout the early and middle Cambrian fossil record but is even more apparent in deposits of exceptional preservation.We know this, at least in part, through the fossil record of marine invertebrates left behind since the Cambrian period.Instead of the typical bell-shaped curve, the fossil record shows a fat-tailed distribution, with extreme, outlier, events occurring with higher-than-expected probability.

Five sentences related to a topic are given below. Four of them can be put together to form a meaningful and coherent short paragraph. Identify the odd one out. Choose its number as your answer and key it in.As a result, discoveries can be made long after a telescope has been decommissioned.In doing so, the Kepler telescope has made “exoplanet research” one of the busiest areas of astronomy.Some of these worlds are far enough from their stars for liquid water to exist on the surface, meaning that these worlds would possibly be hospitable to life.Since then, it has spotted 2700 alien worlds.The Kepler telescope was launched into space in 2009 to look for extrasolar planets, those that circle stars other than the sun.

Choose its number as your answer and key it in.But he has also accelerated the transference of phosphorus from plant and animal life to the sea, thus speeding up its cyclical migration in a two-fold manner.With the development of agriculture in historic times, however, the phosphorus cycle has been seriously upset, for systematic cropping reduces the reserves in the soil more quickly than they can be renewed from fresh sources.For some time after the earth's formation, the phosphorus cycle in the sea was simple, phosphate ions built up into the earliest forms of organic life and released again at their death.Furthermore, the emergence of life from the sea and the colonization of dry land led to a soil-plant-animal-soil cycle, from which phosphorus was removed in negligible quantities in the formation of bone beds, fossil fish or guano deposits.In the past few centuries man has attempted to restore the phosphorus balance by the use of fertilizers, derived largely from natural deposits.

Question No 21.The four sentences (labelled 1, 2, 3 and 4) given below, when properly sequenced, would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the four numbers as your answer.1. The broad range estimates put forward in studies so far also have one thing in common: They're all much greater than the natural background rate.2. From dodos, to golden toads, to Tasmanian tigers, many species have succumbed to our unique blend of destruction.3. Humans are very good at wiping out wildlife.4. The exact number of animal species humans have driven to extinction is unknown, but it could be hundreds of thousands.

Which statement accurately describes the fossil record and its contribution to our understanding of natural selection?Multiple choice question.Paleontologists have found a number of transitional fossils at the predicted positions of time.Scientists have found several transitional fossils, however, they are not located in the predicted positions in time.While the fossil record has greatly improved, scientists have yet to find a good transitional fossil that supports evolution by natural selection.

Scenario: A region is known for its diverse fossil record. Explain how the study of these fossils can provide insights into the geological history of the area.
