Q: Answer the following question given this paragraph: Plants have specialized organs that help them survive and reproduce in a great diversity of habitats. Major organs of most plants include roots, stems, and leaves. Leaves are the keys not only to plant life but to all terrestrial life. The primary role of leaves is to collect sunlight and make food by photosynthesis . Despite the fundamental importance of the work they do, there is great diversity in the leaves of plants. However, given the diversity of habitats in which plants live, it's not surprising that there is no single best way to collect solar energy for photosynthesis. Q: The primary role of leaves is to collect what? Choices: - pollen - insects - precipitation - sunlight A:
A: sunlight

Q: Answer the following question given this paragraph: Diagram of a Cytomegalovirus. The capsid encloses the genetic material of the virus. The envelope which surrounds the capsid is typically made from portions of the host cell membranes (phospholipids and proteins). Not all viruses have a viral envelope. Q: What encloses the genetic material of the virus? Choices: - mitochondria - nuclei - the spindle - the capsid A:
A: the capsid

Q: Answer the following question given this paragraph: Look at the battery and light bulb in Figure below . The light bulb works and it's connected to the battery, but it won't light. The problem is the loose wire on the left. It must be connected to the positive terminal of the battery in order for the bulb to light up. The reason? Electric current can flow through a material such as a wire only if the material forms a closed loop. Charges must have an unbroken path to follow between the positively and negatively charged parts of the voltage source, in this case, the battery. Q: Because charges must have an unbroken path to follow, electric current cannot flow through a material unless it forms what? Choices: - complete loop - closed area - total loop - closed loop A:
A: closed loop

Q: Answer the following question given this paragraph: Echinoderms are named for their "spiny skin. " However, the spines aren't on their skin. They are part of the endoskeleton. The endoskeleton consists of calcium carbonate plates and spines, covered by a thin layer of skin. Adult echinoderms have radial symmetry. This is easy to see in the sea star and sand dollar in Figure above . However, echinoderms evolved from an ancestor with bilateral symmetry. Evidence for this is the bilateral symmetry of their larvae. Q: What type of organism, including sea stars and sand dollars, is named for their spiny skin? Choices: - mollusks - diatoms - chordates - echinoderms A:
A: echinoderms
