What is the common link ? The answer is‚ EUTROPHICATION: a complex process which occurs both in fresh and marine waters‚ where excessive development of certain types of algae disturbs the aquatic ecosystems and becomes a threat

I know that sounds a little corny‚ but I don’t really know any other way of putting it. So many questions start to creep into my head after seeing something so incredible come from something that has been on this earth for

Symbiotic Nitrogen Fixation 1. Rhizobium - Legume Symbiosis Many leguminous plant species can enter into a symbiotic relationship with root-nodule bacteria‚ collectively referred to as rhizobia. The legumes belong to the order Fabales‚ family Leguminosae (alternatively Fabaceae)‚ in eurosid clade I (Doyle and Luckow 2003). Traditionally‚ three main subfamilies are distinguished: Caesalpinoidae‚ Mimosoidae and Papilionidae. Only one nonlegume‚ the woody plant Parasponia sp.‚ can be nodulated

symbionts also changes in symbiosis . There are about 15 ‚000 species of lichens ‚ an indication that this type of symbiosis has been highly successful and has involved many species of fungi . Surprisingly ‚ only about 30 different types of algae and cyanobacteria have been reported as photobionts A lichen thallus usually consists of layers such as an upper and lower cortex ‚ algal layer ‚ and medulla . The layers differ in thickness and are better developed in some species than in others . Fungal hyphae

Phenotype Hypothesis Testing Hypothesis The lack of chlorophyll in kidney beans is due to the environment. Presence of chlorophyll in plants Chlorophyll is a green pigment found in the cyanobacteria and the chloroplasts of algae and plants. Chlorophyll is an extremely important biomolecule critical in photosynthesis‚ allowing plants to absorb energy from lights. Chlorophyll is present in specialised cells within plants and many algae‚ when sunlight is present‚ chlorophyll combines it with water

According to contemporary astronomers‚ what is the chronological evolution of the universe from its moment of inception at the Big Bang to the formation of the Earth? Answer: When we look into outer-space today we see billions upon billions of stars the cover the “universe”‚ but what may have crossed your mind is how did they get there? Well before‚ these stars were there

is a lot of bacteria entering Lake Erie. A few years ago much of Lake Erie was very contaminated with dangerous toxins from algae: “In 2011‚ bright green slime spread across one-third of Lake Erie. The slime was a harmful algal bloom‚ caused by cyanobacteria” (Kowalski 34). As a result of Lake Erie being polluted people must find the issue and resolve it. One theory of the pollution in Lake Erie is that the species are not being managed well enough. Lake Erie must be conserved and the animals must

Expected results in a confirmed case of shigellosis are as follows: Brilliant Green Agar – Isolated Shigella colonies which do not ferment lactose or sucrose and appear red or white in color with no growth to trace growth on the Agar plate will be present. Triple Sugar-Iron Agar – Presence of Shigella will manifest as a red slant with
