Larva

Miles Lamar of the University of Otago in New Zealand performed an experiment where he observed the larva of a species of sea urchin in both normal and acidic water in order to see if their development was in any way hindered. In order to do this, he found several underwater vents that naturally acidify certain parts of the ocean off the coast of Papua…

beneath the bark of the tree and move in a zig-zig pattern along the tree. As travels under the bark and above the thick layer of wood, it lives a silent and dark world. It takes in the nutrients it needs from the tree. While tunneling through tree the larva is causing damage to the tree by feeding on the thin layer of tissue under the trees bark called the cambium. After a few weeks of this it metamorphoses into an adult beetle. The beetle then drills or bores its way out of the tree, causing…

Literary Analysis of The Metamorphosis and Axolotl Franz Kafka’s novella The Metamorphosis and Julio Cortazar’s short story Axolotl are not only based off of the writers themselves; they also exhibit a plethora of similar themes and concepts, including absurdism, alienation, Marxism, and magic realism. Oftentimes in fictional literature, traces of emotions exhibited by characters and events that occur within the fictional work are heavily influenced by the writer’s own dilemmas. This parallel…

female aurelia produces an ovum. When the sperm managed to fertilize the ovum then formed a zygote, this zygote then undergoes self-pembehana several times to form a spherical cell called blastula. Blastula then grows into a ciliated larvae. This larva will find the right place to grow into a polyp. The polyps then grow steadily until they expand and form new buds called strobilization). Over time buds will release one by one into the water into efira, efira then turned into medusa and grow into…

larva has 5 stages of development known as “instars”, and before entering full adulthood can grow up to 5cm. The main human transmission of these bugs is from moving around firewood, live trees or other fallen timber, as the larvae live hidden deep inside…

go extinct its gone forever and there is no getting it back. Losing even one animal or species could have a real bad effect on the rest of the ecosystem, because the effects will be felt throughout the food chain. For example, if we lose mosquitos larva the mosquitos are going to over populate the population and that would be bad for everybody. One animal that is under the ESA is the endangered Bald Eagle. In the 1960’s the Bald Eagle about 500 and could found in under 48 states. The thing…

Endangered eel: Anguilla Japonica Anguilla Japonica, most commonly known as the Japanese eel is classified as an endangered species whose habitat surrounds the coasts of Japan. Based on various credited sources, an analysis was performed in order to determine the likelihood of this eel to go extinct. Biological components and statistical data were taken into account and based on the observed results, it is logical to hypothesize that within a span of years this eel can go extinct. Nonetheless,…

fruit flies lays several eggs. Similarly, fruit flies develop from larvae like other flies (Glick, Neimeier and Aiello). Drosophila melanogaster can reproduce anywhere that has fermented organic matter that stays moist. Fruit flies undergoes 4 (egg, larva, pupa, and adult) stages of metamorphosis during their life span. Depending on the temperature fruit flies’ metamorphosis last from 7 to 50 days, Although fruit flies only have four chromosomes, they have similar gene with human's genes…

project performed by Conor Walsh of California, he predicted that the caterpillars placed in warm temperatures would emerge faster than does placed in cold temperatures. Walsh performed two trials and each trial resulted in the same conclusion “the larva and pupae exposed to warmer temperatures developed into butterflies about twice as fast as those exposed to cooler temperatures.” With warmer temperatures especially in South Texas how does that affect…

Invasive cancer is the cancer that spreads beyond the layer of tissue which developed and is growing into surrounding, healthy tissues. A lot of physicians try to detect and prevent the invasive cancers. Ductal carcinoma in situ is a non-invasive breast cancer. It does not spread beyond the milk duct into surrounding breast tissue. However, it can increase the risk of having invasive breast cancer later. Heterogeneity is a word that means diversity. It signifies the quality of state of being…
