Answer: c)They are more expensive than potatoes without the vaccine.
A genetic engineering is a practice which is integral part of biotechnology which involves the genetic manipulation of organisms. In this the genome of organism is manipulated by incorporating the genome of the other organism, or some part of it is deleted so as to make organism resistance against diseases.
In the given situation, edible vaccines are incorporated in the potato plants, the vaccines are the chemical formulations which includes either the bacterial genome or some of it's agents which can fight against the one already present in the body causing diseases. This entire process requires an expensive technological support as a consequences of which the quality as well as price of these potatoes will be high as compared to conventionally produced potatoes.
Answer is b). They make it easier to administer edible vaccines.
Plant derived edible vaccines dependent on the stability of plant food. Potato is not eaten raw and it needs to be cooked before eating. Cooking causes denaturation or weaken the protein present in it. Edible vaccine is more effective in plant food which eaten raw such as banana. An individual get protected from diseases by simply eating a fruit.
both becuase the 1. if the plant is able to develope in the particular environment and genetics becuase certain plants will grow according to their parents.
The correct answer is letter "B. Conical shape ." The characteristic of a pine tree is an adaptation to the climate of the northwestern coniferous forests is that it is in conical shape. If C were needle like leaves that would be the best answer.
