Exoskeleton

Have you ever wonder how a lobster reacts to pain? The most accepted belief is that they don’t, but they have ways to feel, and they are not human, so their senses are different. Lobsters have complex nervous systems and exquisite tactile sense, and they lack forms of pain instigation that the animal possesses; therefore, humans need to reconsider how they treat this ancient sea creature. Lobsters every day are being killed by the human consumption of one thing: eating. People could go to…

waterproof cuticle that provides an effective barrier to water and salt. This cuticle also provides protection against evaporation and water loss that occurs due to osmosis. Another structural adaptation of the Brown-Barnacle is their calcareous exoskeleton which is strong, and cements them to the rocks. This helps them avoid being broken into or dislodged by predators. Another structural adaptation of the Brown-Barnacle is their small size, which makes them a bad meal for predators. This means…

With the emergence of a new space race in recent years, the topic of space exploration has come under fierce scrutiny. Combustible claims are being thrown into the forges of debate from both the opposing side and those that fervently follow the exploits of the various space agencies. While both sides of this debate have various logical points, they both tend to follow the same well-traveled track. The opposing side of this argument tends to charge forth asking, why should we spend money on such…

What are head lice? The head louse, or Pediculus human capitis, is a parasitic insect that can be found on the head of human beings. Head lice feed on human blood several times a day and need to live close to the scalp to maintain their body temperature. Head Lice Life Cycle The life cycle of the head louse has three stages: nit, nymph, and adult. The life cycle of a single louse from egg to mature adult capable of laying eggs or reproducing is about 21 days. Nits/Eggs: Head lice eggs are called…

colors such as blue, black and, gray. Which happen to be the only colors that Thomas and Lucille wear throughout the entire movie. With the only exception being when Lucille is first introduced, however, even that dress resembles the shape of an exoskeleton. Another, typical color scheme seen in fairytales are light colors often worn by characters that are perceived as “good” such as a fairy, princess, or an angel. In Crimson Peak this role is played by the virginal Edith, who prances around in…

luminescens for growth and reproduction. However, classifying Heterorhabditis bacteriophora as a bacteriovore does not paint the entirety of the bacteriophora, and how it is capable of parasitic adaptations such as host finding, pierce the insect exoskeleton regurgitation of intestinal symbionts after sensing host cues by buccal tooth, and most importantly, the symbiotic relationship with Photorhabdus luminescens. The non-feeding and developmentally arrested infective juvenile stage, is the…

polymers. Carbohydrates regulate blood glucose and breakdown fatty acids. Animals use carbohydrates as a major energy source. Animals store glucose for energy to use while hunting for prey. It is stored as glycogen. In addition, it strengthens the exoskeleton. Carbohydrates strengthen plant cell walls and also store glucose for energy. Plants store it as starch. They can be used to store nutrients for both plants and animals. Carbohydrates strengthen fungal cell walls and form parts of the…

Evaluate the impact of increased understanding of the fossil record on the development of scientific ideas about the history of life on Earth Improved understanding of the type of fossilised arthropod known as a ‘Trilobite’ allowed for subsequent increases in development of the theory of evolution. Since it’s initial drawing by Rev. Edward Llwyd in 1698, multiple improvements in technology as well as collection of specimens have painted a detailed portait of the nature of trilobites as well as…

Effects of Chemicals on Heart Rates in Organisms. Jesutofunmi Bankole El Centro College Abstract This experiment studies the effect of caffeine and alcohol on heart rate. This lab experiment detailed how water flea, (Daphnia magna) a transparent aquatic organism whose heart can be easily identified using a compound light microscope, was used to study the effects of caffeine and alcohol on heart rates. According to the research alcohol was observed to have caused a…
