Q: What is the most important source of energy on earth? Read this paragraph and choose the correct option from the provided answers: The sunlight that reaches Earth is the planet's most important source of energy. The energy in sunlight, called solar energy, is electromagnetic energy. This is a form of energy that travels through space in electric and magnetic waves. Solar energy can be used to heat homes and produce electricity in solar cells like those on the roof seen in the Figure below . Sunny areas receive plenty of sunlight to generate electricity, but solar energy may not be practical in areas that are often cloudy. Choices: - the earth's core - water - moon - sun A:
sun

Q: The scientific practice of classifying organisms is also known as what? Read this paragraph and choose the correct option from the provided answers: 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: . Choices: - taxodermy - terminology - methodology - taxonomy A:
taxonomy

Q: Q: Did the the open circulatory systems of molluscs and arthropods arise dependently or independently of each other? Read this paragraph and choose the correct option from the provided answers: Choices: - dependently - together - separately - independently A:
A: independently

Question: Q: What type of pollution is generated by power plants and factories that can directly raise the temperature of water? Read this paragraph and choose the correct option from the provided answers: Thermal pollution raises the temperature of water. It is commonly caused by power plants and factories. The change in temperature can kill fish and other water organisms. Choices: - atmospheric pollution - Space Pollution - variable pollution - thermal pollution A:
Answer: thermal pollution

Q: What is the tiny male gametophyte enclosed in a tough capsule? Read this paragraph and choose the correct option from the provided answers: Pollen is a tiny male gametophyte enclosed in a tough capsule. Pollen carries sperm to an ovule while preventing the sperm from drying out. Pollen grains can't swim, but they are very light, so the wind can carry them. Therefore, they can travel through air instead of water. Choices: - Cell Capsule - nitrogen - calcium - pollen A:
**Answer**
pollen
