Ques: Answer the following question given this paragraph: Oceanography is the study of the oceans. The word oceanology might be more accurate, since "ology" is "the study of. " "Graph" is "to write" and refers to map making. But mapping the oceans is how oceanography started. Q: What does the ending 'ology' refer to? Choices: - theory of - Application Of - focus of - study of A:
Ans: study of

Ques: Answer the following question given this paragraph: will inevitably make it more difficult and costly to grow food. The world's growing human population faces significant challenges in the increasing costs and other difficulties associated with producing food. Wild Food Sources In addition to growing crops and raising food animals, humans obtain food resources from wild populations, primarily wild fish populations. For about one billion people, aquatic resources provide the main source of animal protein. But since 1990, production from global fisheries has declined. Despite considerable effort, few fisheries on Earth are managed sustainability. Fishery extinctions rarely lead to complete extinction of the harvested species, but rather to a radical restructuring of the marine ecosystem in which a dominant species is so over-harvested that it becomes a minor player, ecologically. In addition to humans losing the food source, these alterations affect many other species in ways that are difficult or impossible to predict. The collapse of fisheries has dramatic and long-lasting effects on local human populations that work in the fishery. In addition, the loss of an inexpensive protein source to populations that cannot afford to replace it will increase the cost of living and limit societies in other ways. In general, the fish taken from fisheries have shifted to smaller species and the larger species are overfished. The ultimate outcome could clearly be the loss of aquatic systems as food sources. Q: Some fish will be over-fished to the point that their species ceases to exist, which is also known as what? Choices: - endangered - accumulation - abundance - extinction A:
Ans: extinction

Ques: Answer the following question given this paragraph: Beryllium hydride consists of a central beryllium atom with two single bonds to hydrogen atoms. Recall that it violates the octet rule. Q: Beryllium hydride consists of a central beryllium atom with two single bonds to what? Choices: - nitrogen atoms - metabolic atoms - calcium atoms - hydrogen atoms A:
Ans: hydrogen atoms

Ques: Answer the following question given this paragraph: The thick, rigid trunk of the oak tree on the left might crack and break in a strong wind. The slim, flexible trunk of the willow tree on the right might bend without breaking. In one way, metals are like willow trees. They can bend without breaking. That's because metals form special bonds called metallic bonds. Q: Metallic bonds allow metals to do what, in the manner of a willow tree? Choices: - break easily - stand tall - grow - bend without breaking A:
Ans:
bend without breaking
