I think the correct answer from the choices listed above is option B. Koalas are the least likely to survive a change in its ecosystem because they only eat eucalyptus leaves. They have limited food as compared to the other choices which are able to thrive at various conditions.

Solid waste Incineration management process involves the burning of solid waste
<u>Explanation:</u>
Incineration is the process of burning of solid wastes. It is one of the processes of solid waste management. In this process, combustion of organic and inorganic wastes takes place that leads to the formation of ash, heat and flue gases. Ash is composed of inorganic constituents.
The heat generated during this process can be used to generate electricity. The process is carried out by Incinerators. Incinerators does not completely replace landfilling but it reduces the volume of disposal of the wastes.
Answer:
a. The original spraying has caused a permanent mutation, giving the insects genetic resistance to the spray.
Explanation:
This is a practical evidences of mutation and variation, as mechanisms of evolution.
The insecticide is the selective pressure. As a results of continuous spray, the parents of the present mosquitoes must have acquired certain characteristics or traits by gene mutation which makes them resistant to the selective pressure (insecticides), and therefore survive the spray in the past.
Therefore when these resistant parents mated, with high reproductive success (leading to large gene pool of these traits,); variation in the genetic composition increases as the resistant gene is passed from generations to generations in the population. Therefore, the population of present day mosquito with genetic resistance to insecticides increases.They are therefore naturally selected, and able to survive as the present day mosquitoes with high resistance to insecticides.
