Answer the following question given this paragraph: Not all changes in matter involve chemical reactions. For example, there are no chemical reactions involved in changes of state. When liquid water freezes or evaporates, it is still water. No bonds are broken and no new products are formed. Q: Changes of state of matter do not involve what type of reaction? Choices: - gaseous reaction - radiation - mechanical reaction - chemical reaction A:
chemical reaction
Q: Answer the following question given this paragraph: Tight junctions are common at epithelia, which are sheets of cells that form a boundary between a mass of cells and a cavity or space (a lumen ). The membranes of these cells join together, forming a virtually impermeable barrier to fluid. Tight junctions essentially seal adjacent epithelial cells in a narrow layer just beneath their apical surface, which is the portion of the cell exposed to the lumen. The rest of the cell surface is known as the basolateral surface. Tight junctions prevent integral membrane proteins from moving between the apical and basolateral surface, maintaining the properties of those distinct surfaces. For example, receptor-mediated endocytosis occurs at the apical surface and exocytosis at the basolateral surface. Q: What is the term for sheets of cells that form a boundary between a mass of cells and a cavity or space? Choices: - mucus - myelin - ganglion - epithelia A:
A: epithelia
Question: Answer the following question given this paragraph: Pollination by Insects Bees are perhaps the most important pollinator of many garden plants and most commercial fruit trees (Figure 32.12). The most common species of bees are bumblebees and honeybees. Since bees cannot see the color red, bee-pollinated flowers usually have shades of blue, yellow, or other colors. Bees collect energy-rich pollen or nectar for their survival and energy. Q: What important function do bees perform on garden plants and many commercial fruit trees? Choices: - hibernation - ruination - condensation - pollination A:
Answer: pollination
