answer these questions, or at least provide some evidence as to what we know so far. The focus will mainly be on the different types of habitable zones, what special resources and properties are required for a potentially habitable planet within one of these zones, and what this all means. Types Circumstellar Habitable Zone A circumstellar habitable zone refers to the habitability potential within a planetary system, and is usually used in reference to one almost identical to our own (Gonzalez, 2005)

small gravitational force at its surface may not be capable of retaining one. The Kepler transit data can only measure planet masses, diameters, orbital periods, and parent star types and although this information is useful for determining habitable zones, further data is required to determine true habitability. The latter can be done by studying the composition of the exoplanet’s atmosphere. The best technology available today for studying the chemical composition of stars and planets is spectroscopy

These three studies investigated the effects of climate change, and in particular increased temperatures in intertidal zones. The study conducted by Bertness et al worked to quantify thermal stresses on rocky intertidal organisms. The species that was focused on was Semibalanus balanoides at sites north and south of Cape Cod. The team analyzed the relationship between thermal stress, population density and individual organism survival rates. While the study conducted by Bertness focused on increases

you down its starving stomach, and its teeth seem to sparkle with hunger. But something else catches eye. Abruptly bolting past you, it swiftly devours a fish twice its size. Welcome to the Pelagic zone. Large organisms roam this open space, and this is perhaps why another name for it is the Open-ocean zone. Including numerous subzones, this limitless territory has includes the subzones of the epipelagic, mesopelagic, bathypelagic, and abyssopelagic. Despite being home to many large predators though

Phytoplankton are the basis of nearly all the Ocean’s ecosystems, and require a wide range of inorganic nutrients in order to grow; notably Carbon, Nitrogen and Phosphorous. They take up these nutrient elements according to the Redfield Ratio of C : N : P = 106 : 16 : 1. But phytoplankton also require less obvious nutrients such as calcium, magnesium and potassium. These are often in plentiful supply in the worlds Oceans, and other factors such as the micronutrient Iron can be the limiting Phytoplankton

The Supra-littoral zone is one of the harshest terrains for organisms to exist in. The organisms that live in this region are facing problems like gas exchange, desiccation, temperature changes and feeding. It is only covered during storms and extremely high tides and is

and in many other countries vehicle safety is paramount. In Fact, many of the automotive manufacturers have spent countless hours trying to exercise immense detail to vehicle safety, and the development to safety devices such as air bags, crumple zones, and frame and body technology. Fortunately, for drivers, these manufacturers have created real life accident scenarios which cover everything from rollovers, to frontal impacts, side impacts, and rear impacts. However, these manufacturers have yet

Biology Internal Assessment 2.6 Edward Sargent Introduction My investigation was to analyse the ecological pattern of zonation within the Pauatahanui Inlet estuary at Motukaraka Point. Our focus was to compare the distribution of invertebrate species from the low tide point to the high tide points of the estuary. This estuary is formed by fresh water from streams meeting saltwater from the Tasman Sea. We found the pattern of zonation by randomly

There are three major intertidal zones including Upper Mid-littoral Zone, Lower Mid-littoral Zone, and the Lower Littoral Zone. These zones allow for different organisms to survive in their preferred tide levels. For example, the upper zone includes organisms that survive in a niche with high tide; where as the lower zone contains organisms with niches in low tidal zones. Within the ecology of intertidal ecosystems lies a food web varying from humans and to microscopic plants such as phytoplankton
