Two neighboring countries of similar size and wealth of resources had different sized population. Deerland had a small population, while Bearland had a large population. Both peoples lived mostly off the land. Given the paragraph above, please answer correctly the following question: Which country had fewer resources per individual? Hint: In nature, when the population size is small, there is usually plenty of food and other resources for each individual. When there is plenty of food and other resources, organisms can easily reproduce, so the birth rate is high. As the population increases, the food supply, or the supply of another necessary resource, may decrease. When necessary resources, such as food, decrease, some individuals will die. Overall, the population cannot reproduce at the same rate, so the birth rates drop. This will cause the population growth rate to decrease.

Answer: Bearland
Q: Company A was a refinery and managed petroleum products. Another company, named company H, produced and distributed electricity using wind power. Both companies strive to be more efficient and to pollute less. Given the paragraph above, please answer correctly the following question: Which company made less fuel for trains? Hint: A major use for petroleum products is fuel for cars, trucks, airplanes, trains, and other vehicles. The chemical used are usually a mixture of compounds containing several carbon atoms in a chain. When the material is ignited, a massive amount of gas is created almost instantaneously. This increase in volume will move the pistons in an internal combustion engine to provide power. A jet plane works on a similar principle. Air comes into the front of the engine and mixes with the jet fuel. This mixture is ignited and the gases formed create a lot of pressure to push the plane forward. The idea can be seen even more clearly in the case of a rocket launch. The ignition of the fuel (either solid-state or liquid) creates gases produced under great pressure that pushes the rocket up.
A: company H
Question: Two sisters went to the hospital. The medics ran some blood tests and found out that Sue had sickle cell trait, while Mary had normal blood cells. Sue received treatment. Given the paragraph above, please answer correctly the following question: Which sister has a specific mutation in the primary sequence of their hemoglobin molecules? Hint: Some individuals have a specific mutation in the primary sequence of their hemoglobin molecules that causes them to aggregate, resulting in a deformation of their red blood cells. This abnormality is genetic in nature. A person may inherit the gene from one parent and have sickle cell trait (only some of the hemoglobin is hemoglobin S), which is usually not life-threatening. Inheriting the gene from both parents will result in sickle cell disease, which is a very serious condition.
Answer: Sue
[Q]: Robert is a scientist that is analyzing the skin cells he obtained from a new species of spider. He is comparing two cells side by side. He notices that the cell on the left, cell A, does not have any enzymes present. The cell on the right, cell B, however contains a large number of enzymes. Given the paragraph above, please answer correctly the following question: Which cell will have slower chemical reactions? Hint: An enzyme is a protein that acts as a biological catalyst. Recall that a catalyst is a substance that increases the rate of a chemical reaction without itself being consumed in the reaction. Cellular processes consist of many chemical reactions that must occur quickly in order for the cell to function properly. Enzymes catalyze most of the chemical reactions that occur in a cell. A substrate is the molecule or molecules on which the enzyme acts. In the urease catalyzed reaction above, urea is the substrate. The Figure below diagrams a typical enzymatic reaction.

input: Please answer the following: Bubba and Dean are two farmers which realized the benefits of having AM fungi in their soil. Dean, however, took active steps in helping the growth of AM fungi so he grew cover crops on his lands. Given the paragraph above, please answer correctly the following question: Which farmer promoted less hyphal growth? Hint: 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.

Two new elements have been discovered by scientists and added to the periodic table. After discussion among their peers, scientists finally decided where to add these new elements. Although both elements are in the same row, Lozopine is on the far right side of the row, and Tralokine is in the middle. Given the paragraph above, please answer correctly the following question: Which element is more electronegative? Hint: The general trend in electronegativity is that the value increases from left to right across a row in the periodic table and decreases down a column. The most electronegative element is fluorine, which has a value of 4.0. As discussed in the lesson "Trends in the Periodic Table," electronegativity increases across a row as the number of protons in the nucleus increases and therefore has a stronger pull. Electronegativity decreases down a column due to an increased effect of electron shielding in larger atoms.

Answer:
Lozopine
