A model created by biologist Luis Valente predicts that the rate of speciation—the rate at which new species form—on an isolated island located approximately 5,000 kilometers from the nearest mainland ______ triple the rate of speciation on an island only 500 kilometers from the mainland.20 Mark For ReviewWhich choice completes the text so that it conforms to the conventions of Standard English? A) being B) to be C) to have been D) will be

Multiple Choice QuestionWhich of the following is the correct definition of the equilibrium theory of island biogeography?Multiple choice question.Gradual changes in gene frequencies occur due to random events.Different gene types will be distributed in the same ratio in offspring as they occur in parents.Diversity in isolated habitats depends on rates of colonization and extinction.Two species interact with each other and one species benefits while the other remains unaffected.

A small number of birds arrive on an island from a neighbouring larger island. This small population begins to adapt to the new food plants available on the island, and their beaks begin to change. About twice a year, one or two more birds from the neighbouring island arrive. These new arrivals ________.Question 9Select one:a.speed up the process of speciationb.tend to promote adaptation to the new food plantsc.tend to slow adaptation to the new food plantsd.represent a colonising event responseClear my choice

In order to prevent nonnative fish species frommoving freely between the Mediterranean and RedSeas, marine biologist Bella Galil has proposed that asaline lock system be installed along the Suez Canalin Egypt’s Great Bitter Lakes.
