The scientists examined both the Eastern and the Western slopes of the mountain. They reached the conclusion that the Western slope was inhabited by many more adult Tasmanian devils than the Eastern slope. Which slope had more devils climbing shrubs up 4 meters high? Hint: The Tasmanian devil is a nocturnal and crepuscular hunter, spending the days in dense bush or in a hole.[64] It has been speculated that nocturnalism may have been adopted to avoid predation by eagles and humans.[65] Young devils are predominantly crepuscular.[66] There is no evidence of torpor.[67] Young devils can climb trees, but this becomes more difficult as they grow larger.[68][69] Devils can scale trees of trunk diameter larger than 40 cm (16 in), which tend to have no small side branches to hang onto, up to a height of around 2.53 m (8.29.8 ft). Devils that are yet to reach maturity can climb shrubs to a height of 4 metres (13.1 ft), and can climb a tree to 7 m (23 ft) if it is not vertical.[70] Adult devils may eat young devils if they are very hungry, so this climbing behaviour may be an adaptation to allow young devils to escape.[71] Devils can also swim and have been observed crossing rivers that are 50 metres (160 ft) in width, including icy cold waterways, apparently enthusiastically.
Ans: Eastern

A group of researches studied the green house gas emissions and their effects on Earth and people during the eighties compared to the twenties. During which decade did Earth experience an increased average global temperature? Hint: Current Situation : Currently the heating effect of extra greenhouse gases (since the start of the industrial revolution) is equal to about . Thus the recent period has recorded parallel increases in concentration of carbon dioxide and average global temperature. As more greenhouse gases are put into the atmosphere the temperature will increase further. There are certain effects of a warmer Earth (discussed more in optional section), which could accelerate the process, even if no more greenhouse gases are put into the atmosphere (an unlikely prospect for the foreseeable future).
Ans: eighties

Keith is a physician in a local hospital. He is treating a patient with respiratory problem. He looked at two different states of the patient's diaphragm, state A and state B. In state A the the diaphragm contracted, but in state B the diaphragm relaxed. He now needs to figure out other phenomena related to this. Would the air pressure inside lungs increase or decrease in state B? Hint: Inhaling is an active movement that results from the contraction of a muscle called the diaphragm. The diaphragm is large, sheet-like muscle below the lungs (see Figure below ). When the diaphragm contracts, the ribcage expands and the contents of the abdomen move downward. This results in a larger chest volume, which decreases air pressure inside the lungs. With lower air pressure inside than outside the lungs, air rushes into the lungs. When the diaphragm relaxes, the opposite events occur. The volume of the chest cavity decreases, air pressure inside the lungs increases, and air flows out of the lungs, like air rushing out of a balloon.
Ans: increase

Bob is a botanist. His interest is in different kinds of fungi. He went to Brazil last month to study fungi in the Amazon rain forest. First day he searched for fungi in a location with excessive moisture. Second day he searched for fungi in a location with no moisture. In all his search he found two specimens of fungi. Specimen A is a brown rot fungus, and specimen B is a honey fungus. Which specimen of fungus would not most likely live on living trees, specimen A or specimen B? Hint: A wood-decay fungus is any species of fungus that digests moist wood, causing it to rot. Some species of wood-decay fungi attack dead wood, such as brown rot, and some, such as Armillaria (honey fungus), are parasitic and colonize living trees. Excessive moisture above the fibre saturation point in wood is required for fungal colonization and proliferation.[1] Fungi that not only grow on wood but permeate its fibrous structure and actually cause decay, are called lignicolous fungi. In nature, this process causes the breakdown of complex molecules and leads to the return of nutrients to the soil.[2] Various lignicolous fungi consume wood in various ways; for example, some attack the carbohydrates in wood and some others decay lignin. The rate of decay of wooden materials in various climates can be estimated by empirical models.[3]
