Introduction When Kudzu, Pueraria montana var. lobata, was first introduced to the United States no one suspected that the semi-woody vine would be capable of enveloping forests across the country. Today, the plant sprawls across an estimated 810,000 hectares of land from Eastern Texas to Florida all the way up to Kentucky. When it was originally planted, Kudzu was seen as a “miracle” plant, able to grow extremely quickly and stop erosion dead in its tracks. Given continuous encouragement by the…
Classification Escherichia coli is a bacterium that is mostly found in humans and other animals. It is a unicellular micro-organism, making its Domain and Kingdom Bacteria. E. coli’s Phylum is Proteobacteria because it is a gram-negative bacterium. It is also in the Phylum Proteobacteria because of the lipopolysaccharides that protect the cell membrane. E. coli is a facultative anaerobic G- bacterium, making its Class Gamma Proteobacteria. Because of its rod-shape, E. coli’s Order is…
The scientific name of a koala bear is Phascolarctos cinereus. A koala bear is a mammal and it is also a herbivore. In the wild, a koala bear can live up to 20 years in age. Size: 23.5 to 33.5 in (60 to 85 cm). Weight: 20 lbs ( 9 kg). Size relative to a 6ft (2-m) man. Koalas live in the eastern Australia, where the eucalyptus trees they love are most plentiful. In fact, they rarely leave these trees, and their sharp claws and opposable digits easily keep them aloft. During the day, they doze,…
The Road to Destruction There is one question that almost everyone askes, even in their childhood. We learn about these amazing creatures from a young age, wondering where they are now, and whatever happened to them. How are we finding the fossils of these creatures, without ever seeing them? How come some are big, and others are small? Why did some eat meat, and others eat plants? Why did dinosaurs disappear? There are three main theories that explain dinosaur’s extinction, and they each have…
Animation films have a way of expanding one’s imagination in a way that ordinary films do not. The ability of the animated movies to make us understand and make a connection with a non-existent world is fascinating. Most animated films are created in imaginary environments, and the characters are created, creatures. This factor explains why some of the characters including animals are given human voices. Walt Disney Pictures produces movies that are meant to be enjoyed not only by children and…
Abstract: This experiment was meant to look and find gene linkages and determine the crosses of the tan x wild type (black), gray x wild type (black), and tan x gray spores of the Sordaria fimicola. To accomplish the crossing, the plates filled with auger had to be set up with each individual kind of spore. Three plates with two different spore colors of sordaria in each. One plate was black and tan, black and gray, and gray and tan. For gene to centromere distance the standard deviation was…

Singh2 1Central Institute of Fisheries Education, Andheri (W), Mumbai 2ICAR Central Coastal Agricultural Research Institute, Ela, Old Goa . Abstract Bioflocs are aggregates (flocs) of algae, bacteria, proto¬zoans, and other kinds of particulate organic matter such as feces and uneaten feed and it normally contains 35-40% of protein. Biofloc technology ensures…
Aromatic plants bear essential oils which are fragrant and so are named ‘Aromatic’. These plants retain their fragrant components in specialised cells and tissues of organs even after drying. Oil may be present in external glands as epidermal cells or their modification such as ‘Secretory Hair’ or may be present internally throughout the plant forming Schizogenous formation which on dissolution of surrounding cells forms Schizolysogenous gland which further grow into long canals. Secretion such…
