Exoskeleton

Our World is Dying Since the beginning, humans have always been able to find ways to make their lives easier. Everyone knows things always come with a cost, and it seems that now, the human race, is paying for it. Air, water, and land pollution has become a part of our everyday life- seeing a piece of trash on the ground has become normal, and even wearing face masks outside in some cities is just a part of their everyday routine. Temperatures are breaking records at such a fast pace, who…

Since the very beginning of the human existence, we have made choices to improve ourselves in order to survive. For every choice we made we had always had to give something up. These improvements in the way we live our lives have always been present, and recently the improvements that show up the most are linked to technology; it is a major concern that technology will change the way we are in the future even more than it is already doing each and every day. Technology will keep changing us like…

Integrated Pest Management What is IPM? Well IPM is a process you can use to minimise or solve pest problems with minimal risk to the people or the environment. Rather than just eliminating the pest with harmful chemicals, IPM uses the climate and the living conditions of the pest to affect the way they live then, create a unfavorable living place for them. This way the pest won’t come back, Why? This is because if you kill the pest then another of the same species will come, if you…

There are certain animals, plants, fungi, bacteria, and viruses that tolerate and actually thrive in extreme conditions. These organisms are called extremophiles. The word extremophile breaks up into “extreme” and the suffix “phile” literally means “one who loves.” These organisms flourish in the uninhabitable places that vary from extremely high and low temperatures, high pressures, high salinity, the absence of water, and extreme amounts of radiation just to name a few. Many of these…

bone abnormalities such as bone pain, fractures, and arthritis. As for protein, insects and other invertebrates are good sources. The dry weight of grasshoppers consists of roughly 50 to 75 percent protein, which forms a large part of the rigid exoskeleton. Insects are a highly digestible source of food for many small mammals. Also, the egg white, or albumin, serves as a source of protein for development of the chick…

deacetylated form of chitin, which is referred to as chitosan. Chitinases digest the chitosan polysaccharide chain at the remaining acetylated sugar residues. Chitin and chitosan are abundant in fungal and some algal cell walls, in bacteria and in the exoskeleton of invertebrates (Li and Roseman 2004). Lipochitooligosaccharides or Nod factors produced by rhizobia essentially consist of a chitin backbone of 3–5-N-acetylglucosamine residues with N-acyl group attached to the non-reducing sugar and…

commodity and stocks of lobsters of all types including berried and under sized ones are exploited around the world. The high value and marketability of lobsters, together with their live-storage potential and the durability conferred by the hard exoskeleton, make them attractive for fishery development in tropical nations (Prescott, 1988). Fishery of berried lobsters and juveniles are banned in many countries aiming the conservation of lobsters. However, adult lobsters including berried ones…

DDT, a white tasteless and almost odorless crystalline solid, is an organochlorine contact insecticide that kills by acting as a nerve poison. DDT is categorized by the WHO as Class II "moderately hazardous". DDT was first synthesized in 1874; it was first used as pesticide in 1937 and for epidemic prevention in the US Army during the Second World War (Eriksson & Talts 2000). Its insecticidal properties were first discovered by Paul Müller in 1939, and it acts on the nervous system through…

As it is shown throughout past events, some people suffer through a type of evilness or loneliness in their life. The struggles that one goes through in these problems affect their daily life and affect how people react near him. In Hemingway’s A Clean, Well-Lighted Place a dark loneliness fills the void of man’s solitary existence, while in O’Brien’s 2006 film Isolation, physical remoteness allows for the entrance of a sinister shadowy evil, each demonstrating, in its own way, nature’s need to…

“It’s a tough world out there when you’re an herbivore, particularly for us insects.” I’m a Green Stinkbug (Nezara viridula). I’ll guide you through some of current battles between us and plants. These battles are constant, and have been on-going since the rise of the first plants and insects. This co-evolution process has developed symbiotic relationships- both good (commensalism) and bad (predation/parasitism) depending on whose side you’re on. The relationships we’ll see are between insects,…
