Answer: The answer should be A: Precipitation.
Explanation: When we take a look at this question, it mentions that there is dew, fog, and clouds on the planet. Infiltration would have probably been evaporated from the ground and became a cloud. The dew and fog would be the condensation. The astronomers notice that there is never any rainfall, and precipitation in the water cycle is rainfall. So therefore, the missing part of the water cycle would be precipitation
they don't transport molecules
Height and weight are quantitative increase in the size of a certain anatomical structure.
<h3>What is Weight?</h3>
The gravitational force acting on the object, expressed as weight as a vector quantity. Some people refer to weight as a scalar quantity that measures the gravitational force's strength. Others define it as the strength of the force applied to a body by systems that work to counteract the effects of gravity. For example, a spring scale measures weight. As a result, the weight would be zero during free fall.
Terrestrial objects are capable of having no weight in this sense. For example, if we disregard air resistance, the famous apple falling from the tree and hitting the ground near Isaac Newton would have no weight.
