Q: Hydrogen and helium are specifically involved as reactants in what nuclear reaction that is useful for making energy? Read this paragraph and choose the correct option from the provided answers: The use of nuclear fusion for energy has several pros. Unlike nuclear fission, which involves dangerous radioactive elements, nuclear fusion involves just hydrogen and helium. These elements are harmless. Hydrogen is also very plentiful. There is a huge amount of hydrogen in ocean water. The hydrogen in just a gallon of water could produce as much energy by nuclear fusion as burning 1,140 liters (300 gallons) of gasoline! The hydrogen in the oceans would generate enough energy to supply all the world's people for a very long time. Choices: - destructive fusion - radioactive fusion - nuclear fission - nuclear fusion A:
nuclear fusion

Read this paragraph and choose the correct option from the provided answers: Bones are the main organs of the skeletal system. The skeletal system also includes cartilage and ligaments. Choices: - lymphatic system - digestive system - endocrine system - skeletal system A:

skeletal system

Ques: Q: What type of plants supplement their mineral nutrition by digesting animals? Read this paragraph and choose the correct option from the provided answers: Choices: - perennials - annuals - herbivorous - carnivorous A:
Ans: carnivorous

(Q).
Q: What disease is caused when the oomycete plasmopara viticola parasitizes grape plants? Read this paragraph and choose the correct option from the provided answers: Plant Parasites Protist parasites of terrestrial plants include agents that destroy food crops. The oomycete Plasmopara viticola parasitizes grape plants, causing a disease called downy mildew (Figure 23.33). Grape plants infected with P. viticola appear stunted and have discolored, withered leaves. The spread of downy mildew nearly collapsed the French wine industry in the nineteenth century. Choices: - dainty mildew - alkaline mildew - toxic mildew - downy mildew A:
(A).
downy mildew

Ques:Q: What are the major types anchoring proteins? Read this paragraph and choose the correct option from the provided answers: Tight junctions are composed of strands of transmembrane proteins embedded in the plasma membranes of two adjacent cells. The extracellular domains of these proteins directly join to one another. These joining proteins associate with peripheral membrane proteins located on the intracellular side of plasma membrane. These peripheral proteins anchor the strands to the actin component of the cytoskeleton, effectively forming a molecular complex that joins together the cytoskeletons of adjacent cells. The major types anchoring proteins of tight junctions are the claudins and the occludins. Choices: - semimetals and occludins - amino and fatty acids - claudins and semimetals - claudins and occludins A:

Ans:claudins and occludins

Ques: Q: Some materials have negative heats of solution; the dissolution of one of these solutes in water is called? Read this paragraph and choose the correct option from the provided answers: Some materials have negative heats of solution; the dissolution of one of these solutes in water is an exothermic process. Heat is released, causing a net increase in the temperature of the solution. Conversely, other substances have positive heats of solution. For example, the dissolution of potassium nitrate in water is an endothermic process. The resulting absorption of energy causes the solution to become colder. Calculations involving heats of solutions follow the same basic approach that we have used with other enthalpy problems. Choices: - endothermic process - acetylene process - ionized process - exothermic process A:
Ans:
exothermic process
