Essay on Analysis of Pearls

Firstly adult female brine shrimp ovulate approximately every 140 hours and in optimal conditions the fertilised eggs can almost immediately hatch, even over a relatively short lifetime of a year this is a lot of young. They have another brilliant reproductive adaption; while in extreme conditions, such as low oxygen level or salinity above 15‰, female brine shrimp produce eggs with a chorion coating which has a brown colour. These eggs, also known as cysts, are metabolically inactive and can remain in total stasis for two years while in dry oxygen-free conditions, even at temperatures below freezing. The shrimp have also been able to survive dangerous salinity levels as the eggs wait to hatch if the salinity levels are too high. Once placed back in briny water the eggs hatch within a few hours. This ability also has enabled them to spread the population by the eggs travelling on the feet of birds. They have also been known to reproduce asexually by parthenogenesis in the absence of

Brine Shrimp are a micro-crustacean that is found mostly in inland saltwater bodies, however, the salinity levels that they live in vary greatly. The conditions that they require can be made at home as the eggs (cysts) of the shrimp are dry, hard shells that can withstand drought and go without water for up to 50 years. This study presents the results of 3 different salinity levelled environments to the Brine shrimp in order to discover a salinity level that produces the most successful hatching rate. By filling 3 Petri dishes with 20mL’s of purified water, each dish contained varying sodium chloride amounts from 15ppt, 25ppt, and

Long ago, native tribes, from many places in the world, depended largely on whales for protein in their diets. They were also able to use much of the whale for oil, thus began a tradition of whaling. The first documented whaling expedition occurred in South Korea

Rose quartz is a mineral composed of oxygen and silicon with the chemical formula SiO2. It is a 7 on Mohs scale of hardness just like any other quartz.Its central gravity is 2.63-2.65. Rose quartz transparency is translucent to transparent. Rose quartz has a vitreous luster and its mineral class is quartz.It is the most abundant mineral found on earth mostly found in the earth's crust.(https://www.crystalvaults.com/crystal-encyclopedia/rose-quartz)

The purpose of this lab was to answer the question, “Of the saline solutions of 0%, 0.5%, 1%, 1.5%, and 2% sodium chloride (NaCl), which solution will yield the highest hatching viability for the brine shrimp?” The hypothesis was that the saline solution most precise to the concentration of NaCl in seawater, which is approximately 3.5%, will yield the highest hatching viability. Therefore, the 2% NaCl solution will yield the highest hatching viability.

To do this, used a reed of a snorkel as a tool to breathe underwater and avoid being spotted. 1300 In the years of 1300, primitive goggles were made by thinly slicing and polishing tortoise shells in Persia. 1538 In the year 1538, a simple diving bell was built by two Greeks.

They are my reminder. They keep my history alive. The tradition began when my Great-grandparents came from Ireland and my Great-grandmother saved all of her money working as a seamstress to buy a small set of pearls for herself. She gifted them to my Nana when she was fifteen years old. My Nana always wore her pearls with pride and used them as a reminder that her life wasn’t always as good as it was. She always told us to humble ourselves and never belittle someone, especially based on what they did or did not have.

In the novel Girl With A Pearl Earring by Tracy Chevalier, Griet faces many challenges which causes her identity to change.

They live in very poor condition. They have a brush house and old, ragged clothing. They eat the same meal of corn cakes almost every day because that is all they can afford.

The aim of this lab is to determine if the Seven River oyster is suitable for oyster restoration. During this lab we learned that Salinity affects the oysters if it is more than 10-13ppt. We also have knowledge that there is a parasite (the protozoan, Haplospordium nelson) that causes the disease MSX in oysters (Readel, 2000). Moreover, at the lab we knew that MSX bacteria will grow if salinity is above 15 ppt that will cause the oysters to die. The oysters can be affected by MSX if the salinity is above 15 ppt (Readel, 2000). Furthermore, Oysters are also used to filter the water of the river. Also, we learned that the range of tolerance of salinity for oysters is 10-27

Throughout this unit I have seen how the lense of perspective is different in everybody's eye and how it’s important to look through the lense of the opposing side and not just our own. A great example that was shown in one of the stories that we read is in “What, of this Goldfish, would you wish” when around half way through the story it switched from the young boys perspective to that of the Russian. Also examples can be taken from the “Texas V.S. Johnson” case and how it can be seen through the perspective of both the government and the people who were burning the flag. There can even be examples from current day events that happen everyday in another part of the world with the video “My So-called enemy” showing how both the Israelis and the Palestinians have their motives for what they fight for. All of

The Pearl, written by John Steinbeck perfectly encapsulates the stringent economic and social divide among the poor and the rich not only on the basis of wealth but also ethnicity and historical divide. This is highlighted by the fact that there was frustration among the people of the village due to their oppression at the hands of their European colonizers. The living conditions of the town were thus very poor. They lived in brush houses and wore ragged clothes, without proper housing or even sanitation. While the European descendants lived in stone houses, surrounded by walls, the Indians, who had been subjugated for over 400 years lived in grass shacks with muddy floors. The situation of the town could be subsequently

Maupassant effectively portrays a marriage that is misunderstood through manipulation, distrust, and deception. He does this by describing each individual, the couple in relation to one another, as well as their lifestyle.

The Pearl written by John Steinbeck is a parable, a story that teaches a moral lesson. The focus of this novel is on a poor Indian family.

With luck on their side, Kino finds a pearl the size of a seagull’s egg; he calls it “The Pearl of the
