How can one element change the world? Well if it is an element like copper then it can change our whole world? Copper allowed for early humans to build new weapons which could help civilizations to win or lose in battle. Copper allowed for the modern revolution thanks to the unique qualities it has that other elements do not. Copper allowed for things such as the telephone to make long distance calls and cell phones which allow us as humans to talk wirelessly to people in another country. It…

Tropical Rainforest The Tropical Rainforest is a really interesting ecosystem. Did you know that the rainforest in southern Asia stretches 3,100 miles on 20,00 islands. Did You also know that some plants in the rainforest can help treat cancer. The tropical rainforest is home to some weird and endangered animals. Location Tropical Rainforest can be located in north South America,west Africa, southern Asia. It stretches from Peru and goes through the Amazon basin to the end of east Brazil.…

of contamination in the water came about after six water samples containing agglomerates were collected around the intake by boat on the afternoon of June 1, 2007. Concentrations of chemical oxygen demand, total nitrogen, total phosphorus, and chlorophyll-a samples came back up to 10 times the normal values usually observed in Taihu.2 On June 3, 2007, spatial distributions of these same chemical concentrations were examined. Peak concentrations of each were about 3–5 times the average…

Energy Flow and Nutrient Cycling in the Epipelagic Zone of the Ocean Introduction: “Energy Flow’’ is an environmental process that describes the flow of energy through a food chain and attempts to ascertain the relative importance of various individual component species and feeding relationships within a particular ecosystem. “Energy” itself is defined as the ability to do work: All living plants and animals expend energy in their environment. All three laws of thermodynamics apply,…

1. Why is the cell theory significant (don’t just state the tenets, explain what it means and why it is a theory)? The cell theory is significant because of it’s three basic ideals or principles. The first is that all organisms are made from cells. This means that cells are the building blocks of life and technically, all of life is connected and related to each other by this tenet. In addition, by researching and examine one type of cell, the results can be assumed for all similar types of…

Lemna is a free- floating aquatic plant from the duckweed family, that consists of small, individual thalli (Tkalec et.al, 2001). Lemna are small, fast growing plants and they develop dense mats on ponds, especially when enough light and nutrients are available (Gérard et.al, 2014). Salt is the most toxic substance, as it causes an inhibition of plant growth and a decrease in nutrient uptake (Chang et.al, 2012). Salt stress induces the production of abscisic acid (ABA), a plant stress hormone,…

2.1 Microalgae. The term microalgae refer to the microscopic algae and the oxygenic photosynthetic bacteria, i.e. the cyanobacteria, formerly known as Cyanophyceae (Richmond 2004). The word algae represent a large group of different organisms from different phylogenetic groups, representing many taxonomic divisions. In general algae can be referred to as plant-like organisms that are usually photosynthetic and aquatic, but do not have true roots, stems, leaves, vascular tissue and have simple…

Because of the lack of water in arid regions, there is a great need to optimize agricultural water consumption. Thus, water conserving is becoming a decisive consideration for agriculture, particularly in arid and semi-arid regions where water is the main limiting factor for plant growth (Moftah and AL-Humaid 2005). Indeed, plants are prodigal in the water use because only roughly 5% of water uptake is used for its growth and development while the remaining 95% is lost for transpiration (Prakash…

What exactly is a “tourist experience”? The concept is both vast and abstract. Does it refer to that special something that travellers talk about upon returning home? Is it what makes people select your destination above others in a very competitive market? We need to establish just what it is that makes our product stand out. In this case, we need to figure out what makes Belgium stand out from other European countries. One reason for me is Belgium being the most strangest European country in…

Carbon is one of the very important elements on planet earth. It contains four valence electrons, which can build essential properties of life, like DNA for example. It has organic properties for the basis of all living organisms. It is necessary for carbon to move through out the planet, through non-living and living things in order to have a balance of energy. Biogeochemical cycling moves carbon throughout the planet into living things and back again. Biogeochemical cycling is a pathway where…
