Geological change will not cause a mass extinction, because it happens on a too big scale - on the scale of millions of years. During such long time, it is more likely that other causes will influence the survival of extinction of species, such as climate change or environmental disasters, and even if there is a small influence, it would not be significant next to other causes.
C. natural selection.
This is because in smaller populations the more that two separate groups of animals don’t interbreeding the father they become until speciation occurs where they cannot interbreed between the two groups.
Answer:
They are more expensive than potatoes without the vaccine.
The genetically modified crops are produced by using the scientific procedures of genetic engineering. It involves the manipulation of the genome of these crops so as to make them disease resistant, improving the quality of the edible parts and increasing the yield of the plants. The crops are genetically modified with accuracy, precision and implementation of the technology therefore, the crops produced are expensive then the crops produce by the conventional method.
Hence, they are more expensive than potatoes without the vaccine is a disadvantage of the genetically engineered potato plants to produce potatoes that contain edible vaccines.
