Robin is an exterminator who is making new mixtures of chemicals to use for when he gets called to kill rats in his neighborhood. To make the mixtures, he has to dissolve nitrogen gas in containers of water. In one container, container A, he dissolves the nitrogen gas under high pressure. In the other container, container B, he dissolves the nitrogen gas under low pressure. Which container will have lower solubility of the nitrogen gas? Hint: Higher pressures increase the solubility of gases. You are probably familiar with this concept as it relates to carbonated beverages. Before opening the container, the inside is pressurized, so a large amount of CO 2 is dissolved in the liquid. After opening, the pressure decreases (to the ambient pressure), so the solubility of CO 2 drops, causing it to bubble out of solution. Because they are not compressible like gases, solid and liquid solutes do not have noticeable changes in solubility at different external pressures.

Answer: container B

Two twin sisters were taken to the doctor's office by their parents. It turned out that Mary had hemophilia while Ann didn't have any blood disease. Which sister had blood that was able to clot? Hint: Hemophilia is the name of a group of hereditary diseases that affect the body's ability to control blood clotting. Hemophilia is caused by a lack of clotting factors in the blood. Clotting factors are normally released by platelets. Since people with hemophilia cannot produce clots, any cut can put a person at risk of bleeding to death. The risk of internal bleeding is also increased in hemophilia, especially into muscles and joints. This disease affected the royal families of Europe.

India decided to introduce several exotic species into their environment, while Singapore was very protective of its native species. Which country introduced more non-native species to the environment? Hint: One of the main causes of extinction is introduction of exotic species into an environment. These exotic and new species can also be called invasive species or non-native species . These non-native species, being new to an area, may not have natural predators in the new habitat, which allows their populations to easily adapt and grow. Invasive species out-compete the native species for resources. Sometimes invasive species are so successful at living in a certain habitat that the native species go extinct ( Figure below ).
