Please answer this: I can use this background: Wildfires occur when all the necessary elements of a fire triangle come together in a susceptible area: an ignition source is brought into contact with a combustible material such as vegetation, that is subjected to enough heat and has an adequate supply of oxygen from the ambient air. A high moisture content usually prevents ignition and slows propagation, because higher temperatures are needed to evaporate any water in the material and heat the material to its fire point. Dense forests usually provide more shade, resulting in lower ambient temperatures and greater humidity, and are therefore less susceptible to wildfires. Less dense material such as grasses and leaves are easier to ignite because they contain less water than denser material such as branches and trunks. Plants continuously lose water by evapotranspiration, but water loss is usually balanced by water absorbed from the soil, humidity, or rain. When this balance is not maintained, plants dry out and are therefore more flammable, often a consequence of droughts.A wildfire front is the portion sustaining continuous flaming combustion, where unburned material meets active flames, or the smoldering transition between unburned and burned material. As the front approaches, the fire heats both the surrounding air and woody material through convection and thermal radiation. First, wood is dried as water is vaporized at a temperature of 100 °C (212 °F). Next, the pyrolysis of wood at 230 °C (450 °F) releases flammable gases. Finally, wood can smoulder at 380 °C (720 °F) or, when heated sufficiently, ignite at 590 °C (1,000 °F). Even before the flames of a wildfire arrive at a particular location, heat transfer from the wildfire front warms the air to 800 °C (1,470 °F), which pre-heats and dries flammable materials, causing materials to ignite faster and allowing the fire to spread faster. High-temperature and long-duration surface wildfires may encourage flashover or torching: the drying of tree canopies and their subsequent ignition from...  Now, I have a new situation: David is an environmental scientist. He needed to find causes of wildfires and suggest preventive measures. First, he visited a dense forest. He marked it as location A. Then he visited a grassland, which he marked as location B. After that, he visited a location where he did not find any sign of drought. He marked it as time A. He then visited the same location a year later, and found that the place was facing a severe drought. He marked it as time B.  Answer this question please: Which place would have lower ambient temperature, locaion A or location B?

Answer: location A


Please answer this: I can use this background: White blood cells also make chemicals that cause a fever. A fever is a higher-than-normal body temperature. Normal human body temperature is 98.6°F (37°C). Most bacteria and viruses that infect people reproduce fastest at this temperature. When the temperature is higher, the pathogens cannot reproduce as fast, so the body raises the temperature to kill them. A fever also causes the immune system to make more white blood cells. In these ways, a fever helps the body fight infection.  Now, I have a new situation: Jim and Pam are a married couple who both have the same illness. They are at home from work today and are in the process of taking their temperatures so they know if they need to go to the doctor or not. After using the thermometer, they learn that Pam has a much higher fever than Jim. They decide they should take Pam to the doctor to get her looked at.  Answer this question please: Does Jim have more or less white blood cells than Pam?

Answer: less


Please answer this: I can use this background: Windbreaks reduce wind velocity over and around crops. This increases yields through reduced drying of the crop and/or by preventing the crop from toppling in strong wind gusts.  Now, I have a new situation: Two farms had winds destroying their crops. Hill farm started installing windbreaks, while Valley farm didn't have the funds to do that so they postponed the project.  Answer this question please: Which farm experienced reduced drying of the crop?
++++++++
Answer:
Hill
