- Q1Tidal pools played a crucial role in the origins of life on Earth because they provideda hiding place for early life formsa source of food for early life formsa stable and concentrated environment for chemical reactions to occura breeding ground for early life forms30s
- Q2Which of the following is not one of the requirements for life to possibly have originated in tidal pools?Stable water levelsHigh levels of oxygenVariations in temperature and salinityAvailability of organic molecules30s
- Q3What is the primary reason why tidal pools are considered potential environments for the origin of life?They have a stable pH levelThey offer consistent temperature and humidityThey concentrate and trap necessary organic compounds and nutrientsThey provide a safe haven for early life forms30s
- Q4What is the main factor that made tidal pools suitable for the origin of life?Abundance of sunlightHigh oxygen levelsProtection from harsh waves and currentsPredominance of plant life30s
- Q5What is the primary source of water vapor in the Earth's early atmosphere?Meteorite impactsPhotosynthesisVolcanic activityEvaporation from oceans30s
- Q6What gas was abundant in the early atmosphere of Earth?NitrogenOxygenWater vaporCarbon dioxide30s
- Q7How did water vapor in the early atmosphere contribute to the formation of oceans on Earth?It condensed and formed rain, filling the basins on Earth's surfaceIt combined with volcanic gases to form volcanic lakesIt evaporated and escaped into spaceIt froze and formed glaciers and ice caps30s
- Q8What process led to the reduction of water vapor in the early atmosphere of Earth?CondensationEvaporationSublimationTranspiration30s
- Q9What was the primary source of nitrogen gas in the early atmosphere of Earth?Meteorite impactsChemical reactions between oxygen and methaneBiological processes of early organismsOutgassing from volcanic activity30s
- Q10Ammonia was a major component of the early atmosphere on Earth.TrueFalseNot mentionedPartially true30s

- Q13In the Stanley Miller and Harold Urey experiment, what was the purpose of their apparatus?To simulate Earth's early atmospheric conditionsTo convert organic molecules into inorganic moleculesTo study the effects of radiation on organic moleculesTo observe the formation of amino acids in living organisms30s
- Q14What did Stanley Miller and Harold Urey use to represent lightning in their experiment?MicrowavesUltraviolet raysElectric sparksFire30s
- Q15What were the gases used in the Stanley Miller and Harold Urey experiment?Methane, ammonia, water vapor, and hydrogenHelium, argon, neon, and xenonCarbon dioxide, oxygen, nitrogen, and hydrogenChlorine, fluorine, bromine, and iodine30s
