Q: What is the process by which wind blows to make the ground surface gets lower and rockier ? Read this paragraph and choose the correct option from the provided answers: Wind blows small particles away. As a result, the ground surface gets lower and rockier; this is called deflation . The rocks that are left are called desert pavement . Desert pavement is a surface covered by gravel-sized particles that are not easily moved by wind. Choices: - inflation - stagnation - layering - deflation A:
deflation

Q: Batteries produce voltage through what type of reaction? Read this paragraph and choose the correct option from the provided answers: Chemical cells are found in batteries. They produce voltage by means of chemical reactions. Chemical cells have two electrodes, which are strips of different materials, such as zinc and carbon. The electrodes are suspended in an electrolyte. This is a substance that contains free ions, which can carry electric current. The electrolyte may be either a paste, in which case the cell is called a dry cell, or a liquid, in which case the cell is called a wet cell. Flashlight batteries contain dry cells. Car batteries contain wet cells. Choices: - liquid - non-chemical - thermal - chemical A:
(Answer)
chemical

Q: How many alleles comes from each parent? Read this paragraph and choose the correct option from the provided answers: When gametes unite during fertilization, the resulting zygote inherits two alleles for each gene. One allele comes from each parent. Choices: - none - two - three - one A:
(A).
one

Ques:Q: What forms when nitrogen and oxygen combine at high temperatures? Read this paragraph and choose the correct option from the provided answers: Nitrogen oxides form when nitrogen and oxygen combine at high temperatures. This occurs in hot exhausts from vehicles, factories, and power plants. Choices: - oxygen oxide - ammonia oxide - carbon dioxide - nitrogen oxide A:

Ans:nitrogen oxide

Ques: Q: What is a molecule with two fatty acids and a modified phosphate group attached to a glycerol backbone? Read this paragraph and choose the correct option from the provided answers: Figure 3.19 A phospholipid is a molecule with two fatty acids and a modified phosphate group attached to a glycerol backbone. The phosphate may be modified by the addition of charged or polar chemical groups. Two chemical groups that may modify the phosphate, choline and serine, are shown here. Both choline and serine attach to the phosphate group at the position labeled R via the hydroxyl group indicated in green. Choices: - carbohydrate - polymer - amino acid - phospholipid A:
Ans:
phospholipid
