The loss of genetic diversity in crop plants can become disastrous. the irish potato famine is an example of this problem. which of the following is not a correct statement about the irish potato famine? most of the potatoes in ireland were propagated from cuttings of the same plant. in the mid-1800s, much of the population of ireland depended on potatoes. the potato originated in ireland. when the crops were infected by a rot-causing mold, all of the potato plants were susceptible and most were wiped out. most of the potatoes in ireland were genetically the same.

The correct option is this: THE POTATO ORIGINATED IN IRELAND.

Explanation:

In 1800, the country of Ireland experienced potato famine, during this period a lot of people died from starvation. The principal reason why this event occur is because most of the potatoes in the country at that time were genetically similar. These potatoes were propagated from cuttings of the same plants, thus, their biodiversity level were quite low. This hamper their ability to resist the fungal disease that destroyed all the potatoes in the country at that time. The variety of potato planted in Ireland at the time of famine was lumper potato, this potato specie originated from another country.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
