[Q]: You are given a new situation: Scientists studied two island. One with an old ecosystem named Old island, and the other with a newly formed and forming ecosystem named New island. Both islands were inhabited, Old island being heavily inhabited. and a hint : Ecology is the study of ecosystems. An ecosystem consists of all the living and nonliving components of the habitat. Whereas nutrients and certain elements are recycled through ecosystems, energy moves in just one direction. Many interactions among species within an ecosystem are centered around the flow of energy. The formation of ecosystems, from new land to current habitats, is usually based on the pioneer species, and these species are able to live in an area due to the nonliving factors, such as the climate, the soil and the amount of rainfall, of that area. The populations within an ecosystem also determine the stability of the system. Recent tremendous increases in the human population have raised many important ecological issues. Please answer this question : Which island had a less stable ecosystem factoring in the population?
****
[A]: Old

[Q]: You are given a new situation: Idaho and Utah had many wildfires. Idaho had more wildfires during the day, while Utah had wildfires occur at night. and a hint : Wildfire intensity increases during daytime hours. For example, burn rates of smoldering logs are up to five times greater during the day because of lower humidity, increased temperatures, and increased wind speeds. Sunlight warms the ground during the day and causes air currents to travel uphill, and downhill during the night as the land cools. Wildfires are fanned by these winds and often follow the air currents over hills and through valleys. United States wildfire operations revolve around a 24-hour fire day that begins at 10:00 a.m. because of the predictable increase in intensity resulting from the daytime warmth. Please answer this question : Which state has fewer wildfires fanned by winds?
****
[A]: Utah

[Q]: You are given a new situation: The health inspectors reviewed data from two villages, Key and Auburn. Key village presented higher levels of both indoor and outdoor pollution. and a hint : Air pollution can also indirectly cause other health issues and even deaths. Air pollutants can cause an increase in cancer including lung cancer, eye problems, and other conditions. For example, using certain chemicals on farms, such as the insecticide DDT (dichlorodiphenyltrichloroethane) and toxic PCBs (polychlorinated biphenyl), can cause cancer. Indoors, pollutants such as radon or asbestos can also increase your cancer risk. Lastly, air pollution can lead to heart disease, including heart attack and stroke. Please answer this question : Which village used less insecticide?
****
[A]: Auburn

[Q]: You are given a new situation: Keith is a zoologist. He studies large predators. Last year, he was studying different species of lions. First, he visited the Gir forest in India. There he found the Asiatic Lions. Unfortunately, only few Asiatic Lions are left in the wild, and they have to mate with their close relatives. He then visited the Serengeti reserve in Tanzania. There he found that the African Lions were not forced to mate with close relatives due to their large number. and a hint : During sexual reproduction, mating with a close relative (inbreeding) often leads to inbreeding depression. Inbreeding depression is considered to be largely due to expression of deleterious recessive mutations. The effects of inbreeding have been studied in many vertebrate species. Please answer this question : Which species of lion would have less deleterious recessive mutations, Asiatic or African?
****
[A]:
African
