Year 9 Science Ecology Symbiosis Symbiosis Symbiosis is the relationship between two living organisms. The main types of symbiosis are mutualism, parasitism and commensalism. The association between the two organisms can be beneficial to one or two of the species or in some cases be harmful, depending on the type of symbiosis. Commensalism Commensalism is a biological term which is used to describe the relationship between two living organisms, where in which one benefits from the other without

The ancient Maya civilisation has generated great interest in many academic scholars and scientists, due to the phenomenon which saw one of the most dramatic civilisation collapses in recorded history, during what has been referred to as the Terminal Classic Period- A.D. ∼700 to 950 (Haug et al, 2003). Interestingly, the ancient civilisation has been characterised by its collapse in the 9th century, perhaps even more so than its remarkable accomplishments, such as: creating vast hierarchical and

Stratum III Stratum III is ubiquitous at both Cienega Amarilla and Cottonwood Canyon exposures. It is typically ~3 m thick at Cienega Amarilla, but it is generally thinner at Cottonwood Canyon. At the Cienega Amarilla spring mound, stratum III consists primarily of spring travertine and tufa facies, whereas muddy paludal facies are predominant in the floodplain areas surrounding the spring mound. In contrast, stratum III at Cottonwood Canyon consists entirely of fluvial deposits. Stratum III was

Abalone (Haliotis midae) is one of the important commercially farmed gastropod species in South African aquaculture (Britz 1995) and it is farmed in intensive land-based, pump ashore, flow-through facilities (Yearsley 2008). The development of the industry has been stimulated by research and development and by a good market demand for abalone both live and processed (Sales and Britz 2001). In abalone farming, the increase in disease outbreaks and their effect on production result in a regular risk

Grant Proposal Mario Williams November 3, 2014 GEO 275 Species on the move: using the fossil record to predict range shifts due to near-future climate change in contemporary tropical marine mollusca Introduction Anthropogenic activity has caused significant transformations to our natural ecosystems due to a diverse suite of interdependent factors. Human action includes the large-scale commercialization and industrialization of activities

PHYSICS PROJECT TO STUDY THE OPTICAL LENS OF A HUMAN EYE Eyes are organs that detect light, and convert it to electro-chemical impulses in neurons. The simplest photoreceptors in conscious vision connect light to movement. In higher organisms the eye is a complex optical system which collects light from the surrounding environment; regulates its intensity through a diaphragm; focuses it through an adjustable assembly of lenses to form an image; converts this image into a set of electrical signals;

<b>Introduction</b><br>Think of a world which existed 290 million years ago. As you look out over the terane in front of you, you think that you are on an alien planet. You see volcanoes spewing ash and lava. Beside them is the ocean which is swarming with many different species of echinoderms, bryozoans and brachiopods. As you look down onto the sea floor you are amazed at the countless number of starfish and urchins. Some animals leave you can't even describe and you have no idea even what phylum

RESEARCH TEACHER SUBMITTED BY: Ibrahim, Mahalia Taskeen R. Cabugatan, Fahad M. Lomansoc, Jake G. Miano, Ryan I. Surmion, Paul Jeffrey S. ABSTRACT Dyes known to the ancients came from plants such as indigo and madder or from the shells of mollusks; today most dyes are made from coal tar and petrochemicals. The chemical structure of dyes is relatively easy to modify, so many new colours and types of dyes have been synthesized. Natural dyes are used as an alternative
