Genetically modified (GM) crops are foods that have had their genomes modified, allowing humans to increase the production of certain crops. Farmer A purchases GM seeds that are immune to a specific herbicide. She plants these seeds in rows over seventeen acres. The following spring, Farmer A's neighbor, Farmer B, tells her that nearly a third of the plants in his crop fields have the same immunity. Which of the following describes the most likely explanation for this occurrence?

a. Rabbits which frequent both fields carried the seeds across to Farmer B's land.

b. Farmer A's crops cross-pollinated with Farmer B's crops on the neighboring land.

c. The two farms share an irrigation system which transmitted the immunity from one field to another.

d. By increasing the genetic diversity in Farmer A's crops, they have out-competed the crops on Farmer B's land.

Herbicide resistant genes may transferred to from Farmer A's plants to farmer B's plants via pollination. Option B is correct.

Jumping Gene:

It is a concept in biology which says that the genes present in the one plant can transfer to another plant via pollination. They are also known as Transportable elements.

Here Herbicide resistant genes transferred to from Farmer A's plants to farmer B's plants.

Therefore, Herbicide resistant genes may transferred to from Farmer A's plants to farmer B's plants via pollination.

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
