Which of the following is a possible scenario that could lead to a new species? A tree frog needs to jump higher to escape preda
tors. The frog's offspring jump higher due to the frequency of jumping by the parent. Over time, many mutations occur in the gene pool of a population of butterflies. A giraffe stretches its neck to reach the leaves at the top of the tree. The offspring are born with necks that are longer than the parents due to the stretching. A bird and a frog reproduce with one another, creating a "brog."
The correct answer would be "Over time, many mutations occur in the gene pool of a population of butterflies".
Speciation is a natural process by which new and distinct species is formed during the course of evolution.
Accumulation of mutations or genetic variations over several generations leads to the change in the genetic make-up of the population which leads to the formation of new species.
Similarly, several mutations in the gene pool of the butterfly population can lead to the formation of new species.
Precipitation differences are the factor that does not contribute to "water stress" on the Earth.
<u>Explanation:</u>
Less ocean water sources, population differences, Scarcity of economic water resources are the factor which leads to water stress on the Earth.
Precipitation differences do not cause much difference in water stress. So it will not contribute to the water stress.
An increase in population will cause major water stress because availability drinking water is less in the earth. Population increase can cause a major problem.
