[Q]: Please answer correctly the following question related to the paragraph below. Which farm didn't provide more time for AM fungi growth into the winter? Two farms were testing new methods to increase production. Timber farm used AM fungi, while Pine farm used other conventional agricultural methods. 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.

[Q]: Please answer correctly the following question related to the paragraph below. Is Fluffy more or less likely than Teddy to pass his genes on to the next generation of bears? Two bears are living in the same forest. One bear, named Teddy, often runs and is active in its daily life. The other bear, Fluffy, is lazy and hardly moves at all. Their levels of fitness are very different with Teddy having a much higher overall fitness level than Fluffy. Hint: All of these animal behaviors are important. They help the animals get food for energy, make sure their young survive, or ensure that they, themselves, survive. Behaviors that help animals or their young survive, increase the animals' fitness. Animals with higher fitness have a better chance of passing their genes on to the next generation. If genes control behaviors that increase fitness, the behaviors become more common in the species. This occurs through the process of evolution by natural selection.

[Q]: Please answer correctly the following question related to the paragraph below. Which team experienced fewer muscle and tendon injuries? Two teams were competing in a 5 km race. White team warmed up before the race, but Blue team arrived with a bus late and didn't have time to warm up properly before the race. Hint: 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 ).

[Q]: Please answer correctly the following question related to the paragraph below. Which student learned less about animals that live in social groups? Manny and Dean were two classmates. They had to prepare for a school project so they decided to learn about animals. Manny studied animal communication, while Dean studied animal feeding patterns and nutrition. Hint: Communication is any way that animals share information. Many animals live in social groups. For these animals, being able to communicate is essential. Communicating increases the ability of group members to cooperate and avoid conflict. Communication may help animals work together to find food and defend themselves from predators. It also helps them find mates and care for their offspring. In addition, communication helps adult animals teach the next generation learned behaviors. Therefore, communication generally improves the chances of animals surviving and reproducing.
