So I see at least three answers here that could potentially be correct, however I believe the best possible answer would be D. they distribute heat around the planet and are a major factor influencing the climate around the globe.
(The other two possibly correct answers would be A. and B. Animals such as Sea turtles will use the ocean currents as a means of quicker transportation and navigation. Sailors would also use the currents as a means of quicker transportation and navigation, however that is not required today with modern technological advances.)<span />

Explanation:
Genetically modified crops are plants used in agriculture, the DNA of which has been modified using genetic engineering methods. Plant genomes can be engineered by physical methods or by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors.
The options for this question are:
- Requires genetic variation
- Results in descent with modification
- Involves differential reproductive success
- All of the above
Answer:
<u><em>The correct option is d) All of the above</em></u>
Explanation:
The theory of natural selection explains that genetic variations occur in organisms of a species. Those organisms which are better adapted to live in an environment are able to survive and pass on their characteristics to their offsprings, hence descent with modification. Through this phenomenon, evolution takes place with the passage of time. Natural selection favours survival of the fittest. Hence, all of the above statements are true.
