I read this background article the other day: Fish reproduce sexually. They lay eggs that can be fertilized either inside or outside of the body. In most fish, the eggs develop outside of the mother's body. In the majority of these species, fertilization also takes place outside the mother's body. The male and female fish release their gametes into the surrounding water, where fertilization occurs. Female fish release very high numbers of eggs to increase the chances of fertilization. I am facing a new situation today: Two different rivers were stocked with adult fish. Red river had a lower fish population because the fish had hardly reproduced naturally. Black river had doubled it's fish population in two years because they reproduced naturally. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which of the two rivers had more fish eggs develop outside of the mother's body?

Answer: Black
Q: I read this background article the other day: Any unused energy in foodwhether it comes from carbohydrates, proteins, or lipidsis stored in the body as fat. An extra 3,500 Calories of energy results in the storage of almost half a kilogram (1 pound) of stored body fat. People who consistently consume more food energy then they need may become obese. Obesity occurs when the body mass index is 30.0 kg/m 2 or greater. Body mass index (BMI) is an estimate of the fat content of the body. It is calculated by dividing a person's weight (in kilograms) by the square of the person's height (in meters). Obesity increases the risk of health problems such as type 2 diabetes and hypertension. I am facing a new situation today: Two groups of people were part of a nutrition study that lasted 2 years. Group A had a normal diet, while group B consumed an extra 1000 calories a day for 2 years. Group B gained lots of weight. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group had fewer people that consistently consumed more food energy then they need?
A: Group A
Question: I read this background article the other day: The Hawaiian Islands ( Figure above ) are in the central Pacific Ocean. The islands are volcanoes that increase in age from southeast to northwest. The youngest island is the Big Island of Hawaii at the southeast end of the chain. The volcanoes get older through Maui, Kahoolawe, Lanai, Molokai, Oahu, Kauai, and Niihau Islands through the northwest. The Kilauea volcano on Hawaii has been erupting almost continuously since 1983. There are also eruptions at an underwater volcano called Loih I am facing a new situation today: Tom and Brad were good friends but lived far away from each other. Tom lived in Hawaii so he visited all the islands and the volcanoes frequently. Brad lived on the East Coast, and he never visited The Hawaiian Islands. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend lived closer to Lanai island?
Answer: Tom
[Q]: I read this background article the other day: 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... I am facing a new situation today: Near the city of Middleton, there are two forests. The Trine forest is a forest tightly packed with trees. Trine has hardly any large open spaces on the ground. The Jimpy forest, on the other hand, is much more open. It has some large areas in the forest that are perfect for camping or for children to play in due to the lack of trees. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which forest would require a lower temperature to burn?
****
[A]: Jimpy
input: Please answer the following: I read this background article the other day: Most chemical reactions within organisms would be impossible under the normal conditions within cell. For example, the body temperature of most organisms is too low for reactions to occur quickly enough to carry out life processes. Reactants may also be present in such low concentrations that it is unlikely they will meet and collide. Therefore, the rate of most biochemical reactions must be increased by a catalyst. A catalyst is a chemical that speeds up chemical reactions. In organisms, catalysts are called enzymes . I am facing a new situation today: Mike is a biochemist, working for a science lab. Today, he has two organisms to investigate, organism A and organism B. He notices that organism A has enzymes, but organism B lacks enzymes. He needs to figure out how these conditions would affect the organisms. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Under normal conditions, in which organism the chemical reactions would be less plausible, organism A or organism B?
++++++++++
output: organism B
I read this background article the other day: Candied fruit, also known as crystallized fruit or glace fruit, has existed since the 14th century. Whole fruit, smaller pieces of fruit, or pieces of peel, are placed in heated sugar syrup, which absorbs the moisture from within the fruit and eventually preserves it. Depending on size and type of fruit, this process of preservation can take from several days to several months.[1] This process allows the fruit to retain its quality for a year.[2] The continual process of drenching the fruit in syrup causes the fruit to become saturated with sugar, preventing the growth of spoilage microorganisms due to the unfavourable osmotic pressure this creates.[3] I am facing a new situation today: Helen got lots of different fruit as a gift from a friend that owned an orchard. She received apples, pears, apricots, peaches, plums, quince, among others. She decided to candy apples, apricots, and pears, and to keep the others fresh for as long as possible. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which fruit lasted longer, pears or plums?
----
Answer:
pears
