Answer the following question given this paragraph: Gnathostomes: Jawed Fishes Gnathostomes or "jaw-mouths" are vertebrates that possess jaws. One of the most significant developments in early vertebrate evolution was the development of the jaw, which is a hinged structure attached to the cranium that allows an animal to grasp and tear its food. The evolution of jaws allowed early gnathostomes to exploit food resources that were unavailable to jawless fishes. Early gnathostomes also possessed two sets of paired fins, allowing the fishes to maneuver accurately. Pectoral fins are typically located on the anterior body, and pelvic fins on the posterior. Evolution of the jaw and paired fins permitted gnathostomes to expand from the sedentary suspension feeding of jawless fishes to become mobile predators. The ability of gnathostomes to exploit new nutrient sources likely is one reason that they replaced most jawless fishes during the Devonian period. Two early groups of gnathostomes were the acanthodians and placoderms (Figure 29.10), which arose in the late Silurian period and are now extinct. Most modern fishes are gnathostomes that belong to the clades Chondrichthyes and Osteichthyes. Q: What is the hinged structure attached to the cranium that allows an animal to grasp and tear its food? Choices: - tooth - neck - throat - jaw A:
(Answer)
jaw

Ques:Answer the following question given this paragraph: Chemists are involved in the design and production of new materials. Some of the materials that chemists have helped discover or develop in recent years include polymers, ceramics, adhesives, coatings, and liquid crystals. Liquid crystals are used in electronic displays, as in watches and calculators. The silicon-based computer chip has revolutionized modern society and chemists have played a key role in their design and continued improvement. The calculator shown below uses both a liquid crystal display and chips inside the device. Q: Polymers, ceramics, adhesives, coatings, and liquid crystals are examples of materials recently discovered or developed by what type of scientists? Choices: - material scientists - engineers - geologists - chemists A:

Ans:chemists
Ques:Answer the following question given this paragraph: The two major divisions of seed plants are the gymnosperms (seeds in cones) and angiosperms (seeds in ovaries of flowers).
