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: Sedimentary rock layers that are not horizontal are deformed. Q: If a sedimentary rock layer is not horizontal, what is it? Choices: - striated - mineralized - igneous - deformed A:
Ans: deformed

Ques: Answer the following question given this paragraph: Inorganic chemical compounds can be broadly classified into two groups: ionic compounds and molecular compounds. The structure of all ionic compounds is an extended three-dimensional array of alternating positive and negative ions. Since ionic compounds do not take the form of individual molecules, they are represented by empirical formulas. Now we will begin to examine the formulas and nomenclature of molecular compounds. Q: Inorganic chemical compounds can be broadly classified into two groups: ionic compounds and which other group? Choices: - cellular compounds - atomic compounds - electromagnetic compounds - molecular compounds A:
Ans:
molecular compounds
