Exoskeleton

2.5.1. Digestive system The digestive tract of the penaeidae shrimp is divided into three regions (Figure 4): namely, foregut, midgut and hind gut. The embryological origin of the epithelial cells in the foregut and hindgut are derived from the ectodermal and covered with cuticle. However, the epithelial cells of the midgut are derived from the entodermal origin. This region of the gut is lack of cuticle; however, it is lined by a peritrophic membrane (Lovett and Felder, 1989, 1990a, 1990b).…

The northern tip of the peninsula encompassing the major cities and metropolitan areas along with smaller urban and rural areas lies in havoc. All nine-counties containing cities, towns, airports; including regional, state, and national parks are in temporal disarray. The peninsulas endured a mass extinction occurring at an uneven rate with widespread and rapid decay in the biodiversity. The essential abiotic components of the ecosystem have altered introducing non-indigenous species with…

Modern Societies Doom without Space Exploration The world without NASA, also known as National Aeronautics and Space Administration, innovation would be a bleak world indeed. Think of all the modern technologies that you use every day without thinking twice about it. Now, imagine them gone! What would our modern society look like? Technologies like power tools, cell phones, modern computer processors, and microwaves are just some of the many contributions that NASA brought to us. Still, there…

because the organelles inside are not so tightly compacted. The cell wall around the plant cell allows the plant to stand tall and upright without the need of bones. Animals have either endoskeletons or exoskeletons to maintain their shape and structure while the cell wall is practically a exoskeleton for a plant to maintain their shape and structure. The cell wall surrounding plant cells is the reason why most plant they have a square or rectangular shape. Another difference is that…

A coelomate has a fluid filled body cavity, which is completely lined by the mesoderm. The organs of a coelomate are suspended within the fluid filled body cavity. This provides protection from any shock put on the organs. This fluid also provides shape to animals without a hard skeleton. Animals like Arthropoda and Echinodermata are examples of coelomates. Acoelomates lack internal cavities and fluid altogether. Their organs are located within the mesoderm which means less protected from shock…

evident connection to the Noir private eye character type that tends to show little to no emotion. Spade’s lack of expression, even in the face of his coworker’s death, is an apparent example of his hardboiled characterization, with an impenetrable exoskeleton, which remains consistent in the Noir genre. It is through these character qualities that one can see the discernable fitting of Sam Spade in The Maltese Falcon and the conventional hardboiled detective of…

low concentration, for their circulation, excretion, and respiration, as they also have no circulatory system like the flatworms. In roundworms, the fluid and muscles that are contained in the pseudocoelom operate as a hydrostatic skeleton, or an exoskeleton that maintains its form due to the pressure of fluid inside the skeleton. Roundworms have two nerve cords that transmit impulses in the roundworm. Also, they are able to reproduce sexually by internal…

Have you ever thought of how a venus flytrap eats? Not many people think about them at all. If you do have any interest in them or nature, It's one of the most interesting things you'll come across. Mostly because all known plants just use basic photosynthesis to feed themselves. not venus flytraps. they are a whole different story. there is no plant like them in any way. So out of all plants that use photosynthesis, some plants needs a little more to their diet, and the venus flytrap has a…

Lewes exposes her perspective that the development of a writer isn’t always a straightforward path through the use of Aristotle’s rhetorical strategies (Pathos, Ethos) and paradoxy to project her message towards Ms. Pierce. In the letter that accomplished author, Mrs. Lewes sends to amateur writer, Ms. Pierce she offers Pathos as a means to capture Ms. Pierce’s attention. Lewes writes about her discoveries through the path of writing through the use of clear, concise imagery; she explains to…

https://microbewiki.kenyon.edu/index.php/Salt_Lake). Brine shrimp range from around 8-10 mm, including the tail. They have nineteen body segments, 11 of them include twenty-two legs total. Brine shrimp have an exoskeleton that with micro-muscles attached to it. The shrimp shed these exoskeletons approximately 12 hours after they hatch, they continue to shed them for up to 17 cycles. ( http://www.ee.pdx.edu/~davidr/discus/articles/artemia.html) Brine shrimp females will also release cysts in the…
