2005). The rules for deep-sea life are different than those for terrestrial species. Stratification plays an important role in species classification in vent environments. As the chimney grows in height the environment changes. Tarasov and associates believe that deep-sea vents have a longer evolutionary history then shallow vents found closer to the surface. This is an important factor in understanding how hydrothermal vents are connected to early life on planet

relationship humans plants. How plants acquire carbon dioxide release oxygen? For purposes plants acquire carbon dioxide? Do a plant survive air tight box plant needed a source oxygen?. Why there would be no people without plants The connection between humans and nature has been a primordial one, actively discussed not only in life sciences but also in literature. Ever since the start of the evolutionary process plants have been an incredible

People without Plants Biology When a person goes into the rainforest or the ocean, that person can readily notice that the rainforest and the ocean are teeming with life. An observer of these places will also notice how every form of life works together to sustain the environment. Though human beings build artificial environments such as cities, humans are a part of the ecosystem on Earth, and they participate in this

Homeostasis may be defined as a self-regulating process whereby equilibrium is achieved between various organs or segments of an organic system, such as the human body. The term "homeostasis" was first coined in 1932 by American physiologist Walter Cannon (Freeman, n.d.), who observed that organisms have mechanisms in place to maintain a constant state of equilibrium or balance. The term has subsequently been utilized to describe this process of maintaining

International Regulation of Tourism in Antarctica Since the mid-1980s, Antarctica has been an increasingly popular tourist destination, despite the relative danger of visiting the largest, least explored -- and arguably least understood -- continent on earth. Beginning with the 1959 treaty establishing Antarctica as an international zone free of claims of sovereignty by nation's that had been instrumental in establishing research stations there, there has been almost constant negotiation about how

In Section 4: Impact of Climate Change on Crops report findings that: 1) Elevated temperature increased their rate of grain growth but shortened the duration of grain filling; 2) Higher temperatures may have decreased the availability of
