Q: I have a new situation: Two cousins went for a blood test. Tim found out he had hemophilia, while John was normal. Tim had to start taking medication. But I can use this background: 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. What is an answer for this question: Which cousin doesn't have a lack of clotting factors in the blood?
A: John

Q: I have a new situation: Mark is a biologist. He is trying to see how to make chemical reactions within organism easier. To that end, he conducts two tests, test A an test B, on an organism. In test A he reduces catalysts from the organism, but in test B he induces catalysts in the organism. He needs to observe the outcomes of these tests. But I can use this background: Most chemical reactions within organisms would be impossible under the conditions in cells. 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 . Essentially, enzymes are biological catalysts. What is an answer for this question: Which test would see reactions taking place slower, test A or test B?
A: test A

Q: I have a new situation: Two soccer players had a friendly match one on one after work. Paul had plenty of time to do his warm up properly, but John got there late and didn't warm up. Paul won the match. But I can use this background: Sometimes muscles and tendons get injured when a person starts doing an activity before they have warmed up properly. A warm up is a slow increase in the intensity of a physical activity that prepares muscles for an activity. Warming up increases the blood flow to the muscles and increases the heart rate. Warmed-up muscles and tendons are less likely to get injured. For example, before running or playing soccer, a person might jog slowly to warm muscles and increase their heart rate. Even elite athletes need to warm up ( Figure below ). What is an answer for this question: Which player didn't warm his muscles up properly?
A: John

Q: I have a new situation: The marine biologists studied two areas of the Black Sea. Area A, situated at the mouth of the Danube River, which presented high levels of water stratification, because of the fresh water discharged by the river; and area B, situated 35 miles south, where the water was less stratified and more oxygenated. But I can use this background: Water stratification is when water masses with different properties - salinity (halocline), oxygenation (chemocline), density (pycnocline), temperature (thermocline) - form layers that act as barriers to water mixing which could lead to anoxia or euxinia.[1] These layers are normally arranged according to density, with the least dense water masses sitting above the more dense layers. Water stratification also creates barriers to nutrient mixing between layers. This can affect the primary production in an area by limiting photosynthetic processes. When nutrients from the benthos cannot travel up into the photic zone, phytoplankton may be limited by nutrient availability. Lower primary production also leads to lower net productivity in waters.[2] What is an answer for this question: Which of the two areas had less dense water?
A:
Area A
