Q: Arachidic, stearic, and palmitic fatty acids are examples of what type of fatty acid? Read this paragraph and choose the correct option from the provided answers: Saturated and Unsaturated Fatty Acids. Saturated fatty acids include arachidic, stearic, and palmitic fatty acids. Unsaturated fatty acids include all the other fatty acids in the figure. Notice how all the unsaturated fatty acids have bent chains, whereas the saturated fatty acids have straight chains. Choices: - neutral - integral - compacted - saturated A:
saturated

Q: Enzymes in cellular reactions work to do what to the reaction? Read this paragraph and choose the correct option from the provided answers: Enzymes are extremely efficient in speeding up reactions. They can catalyze up to several million reactions per second. As a result, the difference in rates of biochemical reactions with and without enzymes may be enormous. A typical biochemical reaction might take hours or even days to occur under normal cellular conditions without an enzyme, but less than a second with an enzyme. Choices: - increase yield - decrease heat - slow it down - speed it up A:
speed it up

Q: Q: Which type of bryophytes are named for their horn-like sporophytes? Read this paragraph and choose the correct option from the provided answers: Liverworts, hornworts, and mosses are modern bryophytes. Liverworts are named for the liver-shaped leaves of some species. Hornworts are named for their horn-like sporophytes. Choices: - arthropods - flatworms - tapeworms - hornworts A:
A: hornworts

Question: Q: What is the color of the powder of a mineral called? Read this paragraph and choose the correct option from the provided answers: Streak is the color of the powder of a mineral. To do a streak test, you scrape the mineral across an unglazed porcelain plate. The plate is harder than many minerals, causing the minerals to leave a streak of powder on the plate. The color of the streak often differs from the color of the larger mineral sample ( Figure below ). Yellow-gold pyrite has a blackish streak. This blackish streak tells you that the mineral is not gold, because gold has a gold-colored streak. Choices: - dye - pigment - hue - streak A:
Answer: streak

*Question*
Q: Birds adapted wings and weathers for flight during what process? Read this paragraph and choose the correct option from the provided answers: Wings and feathers are two adaptations for flight that evolved in birds. Both are clearly displayed in the flying gull in Figure below . Wings evolved from the front limbs of a four-legged ancestor. The wings are controlled by large flight muscles in the chest. Feathers also help birds fly. They provide air resistance and lift. In addition, they provide insulation and serve other roles. Choices: - migration - variation - emergence - evolution A:
**Answer**
evolution

(Q).
Q: How are classic sedimentary rocks group? Read this paragraph and choose the correct option from the provided answers: Clastic sedimentary rocks are grouped by the size of the sediment they contain. Conglomerate and breccia are made of individual stones that have been cemented together. In conglomerate, the stones are rounded. In breccia, the stones are angular. Sandstone is made of sand-sized particles. Siltstone is made of smaller particles. Silt is smaller than sand but larger than clay. Shale has the smallest grain size. Shale is made mostly of clay-sized particles and hardened mud. Choices: - particle depth - density - color - size of sediment A:
(A).
size of sediment
