Edible molluscs

A bivalve is a category of marine and freshwater molluscs and can be located in the deepest depths of the ocean to shallow streams. Bivalves are easily identified due to the distinct quality of two shells attached by a muscular hinge. They can reach a length of 13cm but are often only reach a percentage of that length. Mytilus trossulus are filter feeders and can filter an average of 340 liters of seawater a day (Wildish, 1990). Therefore, blue mussels have a highly efficient method of accumulating bacteria found in the water, thus exemplifying their importance as biological indicators (Hale, 2003). The mytilus trossulus species has been heavily used in the study of oild…

Skepticism is nearly the opposite and can be described as questioning or doubting unempirical knowledge, beliefs, or opinions stated as facts and refrains from claims of truth or knowledge. Skepticism, however, does not state that truth or knowledge is impossible. The difference between these two philosophical ideas can be seen in examples of…

I was in the garden again. The damp soil running through my fingers. The water soaking through the knees of my jeans. I weeded around my beans, feeling the dirt under my fingernails and in the creases of my palms. My first few days here I just watched, unsure of the unspoken rules that hovered over the garden.

Callosobruchus maculatus are not considered directly harmful to humans; although, as an insect pest they damage millions of tons of human food crops in the form of legumes every year (Torres et al. 2016).

Because Callosobruchus maculatus larvae feed and develop exclusively on the seeds of legumes, the beetles are commonly referred to as "bean beetles." Adult Callosobruchus maculatus have a very short lifespan of 6 to 14 days…

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…
