Q: Tuataras, lizards, and snakes are members of what subclass of reptiles? Read this paragraph and choose the correct option from the provided answers: Choices: - dinosaurs - arthropods - staurikosaurus - lepidosaurs A:
(Answer)
lepidosaurs

Ques: Q: In what form of matter is hydrogen at room temperature? Read this paragraph and choose the correct option from the provided answers: A compound has different properties than the substances it contains. For example, hydrogen and oxygen are gases at room temperature. But when they combine chemically, they form liquid water. Another example is table salt, or sodium chloride. It contains sodium and chlorine. Sodium is a silvery solid that reacts explosively with water, and chlorine is a poisonous gas (see Figure below ). But together, sodium and chlorine form a harmless, unreactive compound that you can safely sprinkle on food. Choices: - dissolved - liquid - solid - gas A:
Ans: gas

Q: What is the term for the stalk connecting a leaf to a stem? Read this paragraph and choose the correct option from the provided answers: Figure 30.4 Leaves are attached to the plant stem at areas called nodes. An internode is the stem region between two nodes. The petiole is the stalk connecting the leaf to the stem. The leaves just above the nodes arose from axillary buds. Choices: - cuticle - blades - base - petiole A:
(A).
petiole

Ques:Q: Which forces hold particles together in more ordered states? Read this paragraph and choose the correct option from the provided answers: Chemical energy, the energy stored in molecules and atoms, is one type of potential energy. Certain reactions can cause this energy to be released as heat. Other reactions require an input of energy, in which case the products will store more potential energy than the reactants. When we studied phase changes, we saw a relationship between energy and the state of matter. To melt a solid or boil a liquid, energy needs to be added in order to break up the intermolecular forces holding particles together in more ordered states. The reverse processes, condensation and freezing, release energy, because more favorable intermolecular interactions are formed. Choices: - natural - gravitational - particular - intermolecular A:

Ans:intermolecular

Question: Q: What is the breakdown of unstable elements into stable elements called? Read this paragraph and choose the correct option from the provided answers: Radioactive decay is the breakdown of unstable elements into stable elements. To understand this process, recall that the atoms of all elements contain the particles protons, neutrons, and electrons. Choices: - initial decay - thermal decay - radioactive decrease - radioactive decay A:
Answer:
radioactive decay
