Q: Splitting the nucleus of an atom produces a massive amount of what type of energy? Read this paragraph and choose the correct option from the provided answers: Nuclear energy is produced by splitting the nucleus of an atom. This releases a huge amount of energy. Choices: - likely energy - radioactive energy - sure energy - nuclear energy A:
nuclear energy

Q: How do planets usually rotate to their orbital planes? Read this paragraph and choose the correct option from the provided answers: The axes of rotation of the planets are mostly nearly perpendicular to the orbital plane. Choices: - exactly perpendicular - chaotic - randomly - nearly perpendicular A:
nearly perpendicular

Q: What part of the plant is the main site of photosynthesis? Read this paragraph and choose the correct option from the provided answers: 30.4 Leaves Leaves are the main site of photosynthesis. A typical leaf consists of a lamina (the broad part of the leaf, also called the blade) and a petiole (the stalk that attaches the leaf to a stem). The arrangement of leaves on a stem, known as phyllotaxy, enables maximum exposure to sunlight. Each plant species has a characteristic leaf arrangement and form. The pattern of leaf arrangement may be alternate, opposite, or spiral, while leaf form may be simple or compound. Leaf tissue consists of the epidermis, which forms the outermost cell layer, and mesophyll and vascular tissue, which make up the inner portion of the leaf. In some plant species, leaf form is modified to form structures such as tendrils, spines, bud scales, and needles. Choices: - soil - root - stem - leaf A:
leaf

Q: What element is all life built around? Read this paragraph and choose the correct option from the provided answers: The cell is the basic unit of life. A cell is made of molecules, which are made of elements. All life-which means all bacteria and archaea, all protists, fungi, plants and animals-is built around the element carbon, and four categories of organic compounds: carbohydrates, lipids, proteins, and nucleic acids. These molecules come together to form a cell, which is the basis of life. One particular type of protein, enzymes, are biological catalysts, allowing biochemical reactions to proceed at the rate necessary to maintain life. One other molecule, water, is also essential to life, though water is not an organic compound. Choices: - hydrogen - neon - oxygen - carbon A:
carbon
