What is the effect of the gulf stream on europe a. large waves on the coast of europe b. warm climate in northern europe c. colder climates near the equator d. crashes of warm and cool water in the ocean

The correct answer is (b) Warm climate in northern Europe.

The Gulf Stream causes the climate of Nothern europe to be warmer. It is due to the atlantic ocean currents that causes atlantic drift. There is a more warmer climate in the northern part of Europe. Due to this climatic change both within the ocean and the atmosphere strong cyclones are formed.The Gulf stream is also a source of renewable energy source because of this climatic change.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
