I think the correct answer would be option 1. It is the marine life in the Arctic circle that is most affected by the extinction. It was estimated that about 40% of the endangered animals of this part are in extinction. This is because of climate change and the destruction of their homes. Also, scientists say that the temperature change of this area is increasing rapidly as compared to the rest of the world which means the animals would have to adapt to these conditions and while some can adapt easily, there are those that cannot and would die to extinction.
.Propagating a plant by cuttings will allow you to keep the special characteristics of that plant. Plants grown from seed will often be different from the parent plant and from each other. Propagating a new plant via cuttings avoids the difficulties of propagating by seed.
Disadvantages of propagating stem cuttings are: You will get a lack of genetic diversity and you may potentially increase Insect and Disease weakness in the new plant.
