Answer the following question given this paragraph: This is how ice wedging works. When liquid water changes into solid ice, it increases in volume. You see this when you fill an ice cube tray with water and put it in the freezer. The ice cubes go to a higher level in the tray than the water. You also may have seen this if you put a can of soda into the freezer so that it cools down quickly. If you leave the can in the freezer too long, the liquid expands so much that it bends or pops the can. (For the record, water is very unusual. Most substances get smaller when they change from a liquid to a solid. ). Q: Do most substances increase or decrease in size when they change from a liquid to a solid? Choices: - increase - stay the same - it is unable to be measured - decrease A:
decrease

Ques:Answer the following question given this paragraph: 30.1 | The Plant Body By the end of this section, you will be able to: Describe the shoot organ system and the root organ system Distinguish between meristematic tissue and permanent tissue Identify and describe the three regions where plant growth occurs Summarize the roles of dermal tissue, vascular tissue, and ground tissue Compare simple plant tissue with complex plant tissue Like animals, plants contain cells with organelles in which specific metabolic activities take place. Unlike animals, however, plants use energy from sunlight to form sugars during photosynthesis. In addition, plant cells have cell walls, plastids, and a large central vacuole: structures that are not found in animal cells. Each of these cellular structures plays a specific role in plant structure and function. Q: Cell walls, plastids, and a large central vacuole distinguish plant cells from what? Choices: - parenchyma cells - phloem cells - eukaryotic cells - animal cells A:

Ans:animal cells
