Q: Answer the following question given this paragraph: 22 Classification of Living Things 22.0.1 Classification of Living Things & Naming With so many flora and fauna on planet Earth, there must be a method to classify each organism to distinguish it from others so it can be correctly identified. Classification does not only apply to biology. For example, supermarkets and grocery stores organise their products by classifying them. Beverages may occupy one aisle, while cleaning supplies may occupy another. In science, the practice of classifying organisms is called taxonomy (Taxis means arrangement and nomos means law). The modern taxonomic system was developed by the Swedish botanist Carolus (Carl) Linneaeus (1707-1788). He used simple physical characteristics of organisms to identify and differentiate between different species. Linneaeus developed a hierarchy of groups for taxonomy. To distinguish different levels of similarity, each classifying group, called taxon (pl. taxa) is subdivided into other groups. To remember the order, it is helpful to use a mnemonic device. The taxa in hierarchical order: . Q: The scientific practice of classifying organisms is also known as what? A:

OPTIONS:
- taxodermy
- terminology
- methodology
- taxonomy

A: taxonomy

input: OPTIONS:
- comet
- supernova
- Oort cloud
- nebula Now, answer this question: Answer the following question given this paragraph: Scientists think the solar system formed from a big cloud of gas and dust, called a nebula . This is the solar nebula hypothesis. The nebula was made mostly of hydrogen and helium. There were heavier elements too. Gravity caused the nebula to contract ( Figure below ). Q: Scientists think the solar system formed from a big cloud of gas and dust called what? A:
A:
output: nebula

Answer the following question given this paragraph: Living in a large colony requires good communication. Ants communicate with chemicals called pheromones. For example, an ant deposits pheromones on the ground as it returns to the nest from a food source. It is marking the path so other ants can find the food. Honeybees communicate by doing a "waggle dance. ". Q: Pheromones enable what, which is vital for organisms like ants that live in a large community? A:

OPTIONS:
- adaptation
- asexual reproduction
- migration
- communication

Answer: communication

Problem: OPTIONS:
- gases
- oils
- plasma
- solids
Q: Answer the following question given this paragraph: The properties of liquids are intermediate between those of gases and solids but are more similar to solids. In contrast to intramolecular forces, such as the covalent bonds that hold atoms together in molecules and polyatomic ions, intermolecular forces hold molecules together in a liquid or solid. Intermolecular forces are generally much weaker than covalent bonds. For example, it requires 927 kJ to overcome the intramolecular forces and break both OH bonds in 1 mol of water, but it takes only about 41 kJ to overcome the intermolecular attractions and convert 1 mol of liquid water to water vapor at 100C. (Despite this seemingly low value, the intermolecular forces in liquid water are among the strongest such forces known!) Given the large difference in the strengths of intra- and intermolecular forces, changes between the solid, liquid, and gaseous states almost invariably occur for molecular substances without breaking covalent bonds. Q: The properties of liquids are intermediate between those of gases and solids but are more similar to? A:
Answer: solids

Answer the following question given this paragraph: Many common electric devices, such as doorbells, contain electromagnets. If they have moving parts, they are likely to have an electric motor. An electric motor is a device that uses an electromagnet to change electrical energy to kinetic energy. Q: What do electric motors use to change electrical energy into kinetic? A:
****
A:
electromagnets
