Q: I have a new situation: Mary's lake was full of fish, the lake's environment was very healthy. Mary stopped fishing on this lake five years ago and maintained it properly. Jane's lake had high fish mortality both from fishing and pollution, and disease from overstocking. But I can use this background: Fish mortality is a parameter used in fisheries population dynamics to account for the loss of fish in a fish stock through death. The mortality can be divided into two types: Natural mortality: the removal of fish from the stock due to causes not associated with fishing. Such causes can include disease, competition, cannibalism, old age, predation, pollution or any other natural factor that causes the death of fish. In fisheries models natural mortality is denoted by (M).[1] Fishing mortality: the removal of fish from the stock due to fishing activities using any fishing gear.[1] It is denoted by (F) in fisheries models. What is an answer for this question: Which lake had a lower water pollution?
A: Mary's
Question: I have a new situation: Two farms were testing new methods to increase production. Timber farm used AM fungi, while Pine farm used other conventional agricultural methods. But I can use this background: Since AM fungi are biotrophic, they are dependent on plants for the growth of their hyphal networks. Growing a cover crop extends the time for AM growth into the autumn, winter, and spring. Promotion of hyphal growth creates a more extensive hyphal network. The mycorrhizal colonization increase found in cover crops systems may be largely attributed to an increase in the extraradical hyphal network that can colonize the roots of the new crop (Boswell et al. 1998). The extraradical mycelia are able to survive the winter, providing rapid spring colonization and early season symbiosis (McGonigle and Miller 1999). This early symbiosis allows plants to tap into the well-established hyphal network and be supplied with adequate phosphorus nutrition during early growth, which greatly improves the crop yield. What is an answer for this question: Which farm provided more time for AM fungi growth into the spring?
Answer: Timber
[Q]: I have a new situation: Two smoker friends found out more about cancer. Bill got scared and started making healthy lifestyle choices, while Dan carried on with his life as if nothing happened. 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 friend decided not to use sunscreen?
****
[A]: Dan
input: Please answer the following: I have a new situation: Park city used fossil fuels to produce their electricity. They were less conscious about the environment than their neighbors from Lake city. People from Lake city used nuclear fission as an energy source. But I can use this background: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution, acid rain, and global warming. Fossil fuels are also limited and may eventually run out. Like fossil fuels, radioactive elements are limited. In fact, they are relatively rare, so they could run out sooner rather than later. On the other hand, nuclear fission does not release air pollution or cause the other environmental problems associated with burning fossil fuels. This is the major advantage of using nuclear fission as a source of energy. What is an answer for this question: Which city caused more acid rain?
++++++++++
output: Park
Please answer this: I have a new situation: The country of Qatar is opulent, to say the least. They have one of the highest per capita income in the world - exceeding that of Western Europe and North America. Over-consumption is the way of life in Qatar. While similarly small country of Bhutan puts emphasis on the happiness of its citizens in a different way. Bhutan does not give way to material over-consumption like Qatar does - it cares about its citizens' spiritual and social well-being. But I can use this background: Overconsumption is a situation where resource use has outpaced the sustainable capacity of the ecosystem. A prolonged pattern of overconsumption leads to environmental degradation and the eventual loss of resource bases. What is an answer for this question: Which country would most probably face environmental degradation, Qatar or Bhutan?
++++++++
Answer: Qatar
Question: I have a new situation: Two plants of the same type are growing near the outskirts of the Jorah forest. The first plant, colored red, is healthy and has no fungus on it. The other plant, colored black, has a fungus growing on the roots of it. These plants have been around for centuries and if crushed into a powder actually make a nice seasoning to add to a meal. But I can use this background: A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant's root system. The larger surface area improves water and mineral nutrient absorption from the soil. What is an answer for this question: Which color plant is not involved in a mycorrhiza association?
Answer:
red
