Exoskeleton

these meteorites gave rise to organic compounds, or life's building blocks. The Cambrian Period lasted from 541 to 485 million years ago. Scientist discovered here that the first signs showed up in water. This led to the discovery of the first exoskeletons and new animals that were appearing in the Caribbean seas. This period had a lot of…

polysaccharide, with β-(1-4)-linked N-acetyl-D-glucosamine. Found in the exoskeletons of crustaceans (crab, shrimp, lobster, insects) & molluscs, as well as the cell walls of algae and fungi, chitin is the second-most naturally abundant polysaccharide after cellulose [1, 2]. Chitin occurs naturally in the polymorphic forms: α, β and γ. The α-polymorphic form of chitin is the most abundant in nature, present in the strong exoskeleton of crustaceans [6]. α-Chitin forms tightly compact…

Animal behavior, by definition, is the behavior within all the living animals. However, what is exactly called behavior? Does each individual animal possess unique behavior regard any stimuli? Do all the animals born with the unique behaviors? All the curiosities trigger the study of behaviors, which are known as ethology. Behavior is the action that carried out by animals in response of environmental stimulus. Ethologists group all the behaviors into two categories: learned behaviors, are those…

Although mainly depicted for use in the military, some have already been made for use in paraplegics. BMX rider Steven Sanchez was offered the opportunity to demo SuitX’s latest design, the Phoenix exoskeleton, in late 2015 for a pricey $40,000 (Brewster). By using motors attached to normal orthotics and crutches designed with controls for the suit, the user is able to control the movement in their legs and walk at a speed of about 1.1 mph (Brewster)…

Honeybees are social insects that live in hives. Bees have a three body part, 6 legs, a pair of antennae, compound eyes, jointed legs, and a hard exoskeleton. The three body parts are the head, thorax, and abdomen. The thorax is the middle part of the bee that is between the head and abdomen. In the thorax is where the two pairs of wings and six legs get support from. Do you know how many wings a bee has? The answer is four. Two wings are attached in the front and two wings are attached in the…

CHAPTER 2 REVIEW OF RELATED LITERATURE AND STUDIES This chapter contains a compilation of local and foreign literatures and studies about the topic researched and are provided as a guide for the hypothesis of this research and served as a basis for the methodology of the study. These provided studies were also used to support the study and compare the difference of the present. DIABETES According to the International Diabetes Federation (2013), diabetes is one of the most challenging health…

CALCIUM Calcium is a mineral found in many foods. The body needs calcium to maintain strong bones and to carry out many important functions. Not having enough calcium can cause many health problems. Calcium insufficiency also causes weak bones and tooth decay. This is because almost all calcium is stored in bones and teeth. This program will help you better understand the importance of calcium in the body and how you can make sure you are getting the right amount. Calcium is the chemical…

of eyes and seven sets of legs, along with a pair of antennæ. Also, by examining the length of their antennæ, males tend to have longer ones than females, and females, notably and potentially show their eggs on the underside or backside of their exoskeleton. Then, it is shown that the larger pill bugs are more apt to be cannibalistic than normal ones as they are able to do so, eat and prey on others. However, this is not a significant issue as the larger they seem to be, it correlates with…

Mealworms are common insects. Mealworms infest stored products. The mealworm/darkling beetle’s scientific name is Tenebrio molitor. As larvae, mealworms are long and cylindrical, with hard light-brown bodies. Mealworms grow to become darkling beetles with a 2-3 centimeter long black body. The larvae, the only point in the insect’s life when the insects are called mealworms, become fully grown into beetles in close to 3 months. The mealworm/darkling beetle’s life cycle is as follows. The insect…

can be a bad thing, like with mosquitos. But think about how many crops that are saved by bugs that eat crop damaging bugs. The way that bugs use origami is in their wings. When bugs are done using their wings they have to fold them in their hard exoskeleton so they don’t get damaged. What are ways you can see origami helping you in your everyday life? How can you bond with other people using origami? When do you think you will use origami? Origami has had a big impact on my life by making my…
