Please answer this: I have a new situation: The southern province was exposed to intensive grazing for many years , and now soil quality is poor and dust storms are present. The northern province has more fertile soil, more trees. But I can use this background: Besides anthropogenic productivity of the land, the biodiversity of degraded land also declines, as previously mentioned.[12] With less biodiversity, this ecosystem is less adaptable to when disasters strike it[11][8] It has a smaller available food supply, in terms of plants, for animals, who then may die out or more likely may relocate. Proof of this decline is that presently 15-20% of Tibetan Plateau species are now considered endangered; and now because of this animal and plant absence, the soil quality of these degraded lands is very poor.[1] It does not hold the necessary nutrients, such as water, nitrogen, and carbon, essential to either supporting life or inviting life back to that land.[6] As a result of such carbon and nitrogen loss in the Tibetan Plateau, $8,033/ha and $13,315/ha were respectively lost in economic terms. Soils are further weakened by dust storms whose frequency increases because of degradation.[11][4] Erosion of soil becomes a bigger problem, since no longer are there as many plants to anchor in the soil. In the northern Chinese province alone, 400 million are affected every year with an associated 54 billion yuan of annual economic loss due to grassland degradation. What is an answer for this question: Which province experiences more carbon loss?

Problem: I have a new situation: Danny went camping and made a fire in the woods. he used large logs he fell a few months back. Bob was camping 300 yards away and he made a fire using small sticks, kindlings and sawdust he had left over. Bob's fire burned fast and bright. But I can use this background: A large log placed in a fire will burn relatively slowly. If the same mass of wood were added to the fire in the form of small twigs, they would burn much more quickly. This is because the twigs provide a greater surface area than the log does. An increase in the surface area of a reactant increases the rate of a reaction. Surface area is larger when a given amount of a solid is present as smaller particles. A powdered reactant has a greater surface area than the same reactant as a solid chunk. In order to increase the surface area of a substance, it may be ground into smaller particles or dissolved into a liquid. In solution, the dissolved particles are separated from each other and will react more quickly with other reactants. What is an answer for this question: Which person made a fire that burned less bright?

A: Danny
Problem: Given the question: I have a new situation: Fred was a good athlete in his youth, and so was Vic. Fred started eating junk food and other fatty foods in his 30's. His cholesterol is very high now. Vic became a vegan later,and he is in a very good physical shape. But I can use this background: Cholesterol has been implicated in heart disease for decades. Atherosclerosis is a disorder of the arteries in which cholesterol and other materials are deposited on the interior of the arterial wall. These deposits lead to the formation of plaques that can restrict or even block the flow of blood through these blood vessels (see Figure below ). A decrease in the flow of blood can lead to high blood pressure and a lowered oxygen supply to the heart muscle. A complete blockage of blood flow to parts of the heart (a heart attack) can cause significant damage due to oxygen deprivation, in some cases leading to death. What is an answer for this question: Which friend had a greater chance of developing atherosclerosis?

input question: I have a new situation: Henry and Tiffany are performing chemical reactions in their high school chemistry class. Henry performs his reactions with the use of a catalyst. Tiffany performs the same reaction with no catalyst present. But I can use this background: A catalyst is a substance that increases the rate of a chemical reaction. A catalyst is a substance that increases the rate of a chemical reaction. The presence of a catalyst is one of several factors that influence the rate of chemical reactions. (Other factors include the temperature, concentration, and surface area of reactants.) A catalyst isn't a reactant in the chemical reaction it speeds up. As a result, it isn't changed or used up in the reaction, so it can go on to catalyze many more reactions. What is an answer for this question: Could Tiffany change other aspects of her reaction besides adding a catalyst to influence its rate, yes or no????
output answer: yes
I have a new situation: Paul started a healthy lifestyle because he wanted to avoid getting cancer. His cousin Pete laughed at him, and continued eating fast-foods, smoking and disregarding his health completely. But I can use this background: Making these healthy lifestyle choices can also help prevent some types of cancer. In addition, you can lower the risk of cancer by avoiding carcinogens , which are substances that cause cancer. For example, you can reduce your risk of lung cancer by not smoking. You can reduce your risk of skin cancer by using sunscreen. How to choose a sunscreen that offers the most protection is explained below ( Figure below ). Some people think that tanning beds are a safe way to get a tan. This is a myth. Tanning beds expose the skin to UV radiation. Any exposure to UV radiation increases the risk of skin cancer. It doesn't matter whether the radiation comes from tanning lamps or the sun. What is an answer for this question: Which cousin reduced the risk of lung cancer by not smoking?

Answer: Paul
Q: I have a new situation: A large group of bears lives in a forest. Over time the climate of the forest changes and becomes very cold. Some of the bears have thicker fur while some of the others have thinner fur. Due to the cold weather the bears with thinner fur die earlier. Also the bears with thicker fur have an easier time finding mates. Because of this the bears with thick fur have their traits passed on more often and bears with thin fur appear less and less in the population But I can use this background: New species develop naturally through the process of natural selection . Due to natural selection, organisms with traits that better enable them to adapt to their environment will tend to survive and reproduce in greater numbers. Natural selection causes beneficial heritable traits to become more common in a population and unfavorable heritable traits to become less common. For example, a giraffe's neck is beneficial because it allows the giraffe to reach leaves high in trees. Natural selection caused this beneficial trait to become more common than short necks. What is an answer for this question: Will a forest where all of the bears have thick fur be in a warm climate or a cold climate?
A:
cold climate
