How might spontaneous generation be possible in a reducing environment? question options: the reducing environment was created by the abundance of methane, which contains carbon. because all life is organic, and organic molecules are all carbon-based, these molecules were the source of the spontaneous generation of life. without oxygen, biological molecules, such as amino acids do not easily break down. as a result, they could have formed a "soup" of organic molecules in the oceans of the past, allowing spontaneous generation to occur. the concentration of nitrogen in the atmosphere created this reducing environment. because nitrogen is present in amino acids, nucleic acids, and lipids, this environment favored conditions that eventually formed life through spontaneous generation. with high concentrations of carbon dioxide, biological molecules could have performed photosynthesis and pumped oxygen into the air in sufficient amounts over about 2 billion years, making spontaneous generation possible.

An experiment is designed to test the relationship between the initial height of a basketball before it is dropped to the height of its rebound bounce. the height of the rebound bounce is measured using a scale positioned behind the ball. in the above experiment, which condition would not be controlled? a). the starting height of the ballb). the surface the ball bounces on c). the type of ball d). the method to measure the rebound height of the ball

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0Ā° above the horizontal. it then moves 127 ft at an angle of 46.0Ā° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
