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

A bird population only eats a certain type of plant. One year, flooding washes away most of these plants in an area. What will most likely result? immigration followed by competition competition followed by immigration emigration followed by competition competition followed by emigration

Read each of the scenarios below. Then, select the option that best represents a scenario illustrating natural selection.A In a population of birds, those with larger beak sizes are better able to crack open tough seeds, providing them with a food source during periods of scarcity. Consequently, the average beak size in the population decreases.B In a population of flowers, those with a particular color variation attract more pollinators and produce more offspring. As a result, the proportion of flowers with that color variation decreases over generations.C In a population of rabbits, those with longer legs are more successful at outrunning predators and are more likely to survive and reproduce. Over time, the average leg length in the population increases.D In a population of fish, those with brighter colors are more easily spotted by predators, leading to higher mortality rates. As a result, the proportion of fish with bright colors increases over time.

Genetic drift is Blank______.Multiple choice question.gradual changes in gene frequency due to random eventsa loss of genetic diversity due to a catastrophic event where few members of a species survivethe maintenance of gene frequencies between generationsthe theory that smaller islands tend to have fewer species

During periods of rapid environmental change, what may happen to a species that was well-suited to the former environment?Group of answer choicesTraits that were favorable in the original environment may be detrimental in the new environment.Individuals with particular traits that provide an advantage in the new environment will have higher reproductive success.The population may change so much in adapting to the new environment that it is considered a new species.A, B. C and D are correct

When a species from a mainland population colonizes an isolated island, and, over time, evolves and diversifies into multiple new species due to the new conditions on the island, this process is calledMultiple choice question.homologous recombination.Wallace's paradox.adaptive radiation.coevolution.
