Q: Q: A chain of what structures form as an oceanic plate moves over a hotspot? Read this paragraph and choose the correct option from the provided answers: A chain of volcanoes form as an oceanic plate moves over a hotspot. This is how it happens. A volcano forms over the hotspot. Since the plate is moving, the volcano moves off of the hotspot. When the hotspot erupts again, a new volcano forms over it. This volcano is next to the first. Over time, there is a line of volcanoes. The youngest is directly above the hotspot. The oldest is the farthest away ( Figure below ). Choices: - ridges - earthquakes - outcrops - volcanoes A:
A: volcanoes

Q: Q: What is it called when something is unable to move from place to place? Read this paragraph and choose the correct option from the provided answers: Sponges come in a variety of shapes and sizes. For example, they may be shaped like tubes, fans, cones, or just blobs. They range in diameter from about a centimeter (0.4 inches) to over a meter (3.3 feet). Many species live in colonies that may be quite large. Adult sponges are sessile . This means they are unable to move from place to place. Root-like projections anchor them to solid surfaces such as rocks and reefs. Choices: - Undrate - obovate - ovate - sessile A:
A: sessile

Q: Q: What kind of energy positions do electrons occupy during ground state? Read this paragraph and choose the correct option from the provided answers: Oxygen has 6 valence electrons in its ground state. Remember that ground state refers to the neutral atom in which the electrons occupy the lowest possible energy positions. Oxygen is two electrons away from being isoelectronic with the nearest noble gas. Oxygen will therefore form ions by gaining two electrons to become isoelectronic with neon, as shown below:. Choices: - closest energy positions - relative energy positions - highest energy positions - lowest energy positions A:
A: lowest energy positions

Q: Q: The first plants probably evolved from what? Read this paragraph and choose the correct option from the provided answers: The first plants probably evolved from aquatic green algae. They had male and female reproductive organs. However, they lacked true stems, roots, and leaves. Choices: - dry green algae - moss - mould - aquatic green algae A:
A: aquatic green algae
