Which of the following is an example of a positive feedback loop: I. As the Earth’s surface warms due to global warming, water evaporation from a lake will initially increase.  As the lake level drops, the surface area decreases and evaporation also decreases.
II. Water vapor from ocean evaporation creates low altitude clouds.  Sunlight that would normally warm the Earth’s surface is instead reflected back to outerspace.
III. Water vapor from ocean evaporation creates high altitude clounds.  Heat that would typically escape the atmosphere into outer space is trapped in the atmosphere instead.

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
