Crawfish Aquatic Analysis

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.

Reaching a length of up to 5.5 centimeters (or about 2 inches), the bigclaw snapping shrimp is the largest member of the family Alpheidae, which are also known as the pistol shrimp. It is found in water up to 30 meters (98 feet) deep from as far north as North Carolina’s Outer Banks to the Brazilian coast. It also is able to survive in areas of rapidly different salinity; A. heterochaelis has be found in environments that range from mesohaline (having a salinity of 5 to 18 parts per thousand) to hyperhaline (having a salinity of 40+ ppt). This means that it lives in environments that range from brackish to seawater of above average salinity. It is most commonly found in areas where cover can be easily found during the day, such as an oyster reef.

Temperature had a direct effect on oxygen consumption of crayfish, Orconectes propinquus. Crayfish acclimated to warm temperature (20 to 25 C) had a mean mass of 8.25g +/- 1.05. Crayfish acclimated to cold temperature (3 to 5 C) had a mean mass of 10.61g +/- 0.77. Oxygen consumption rates of 30-60 minute treatments were used and there was no significant difference between the two different treatments (t=0.48, df=58, P=0.70). The data from 0-30 minutes were not used because the crayfish were disrupted by transportation and the data were not normally distributed. The Q10 value was 1.05, representing that there was full compensation for oxygen consumption for the crayfish at two different acclimated temperatures. The oxygen consumption of crayfish was not affected significantly by two different temperatures (Figure 1).

It’s almost Mardi Gras time, and we can’t think of a way we like to celebrate better than a big old crawfish boil (or crayfish, or crawdads, or mudbugs, or whatever you call them). These tiny, freshwater crustaceans are basically tiny lobsters, but that doesn’t stop them from perplexing people from outside Fat Tuesday’s homeland year after year.

The frosty morning breeze snaps at your ears and nose as you step away from the warm aroma of the bus, so you rush inside to the sports center. As you scurry in, you are stopped abruptly, meeting a large crowd of strangers gathered in the main entrance. There is barely room to squeeze past anyone, as every swimmer in New York who qualified for States, was in this one building. You finally find your way to the pool. After walking past several team banners, you finally see the banner labelled “Auburn Stingrays” and you spot your mom and dad off to the side, setting up a blanket for you to sit on. You toss your bag down and hug your parents for a final good luck before the meet. After you part from the hug, your hair is tousled by you dad, and they turn to go find a good seat before it gets filled up. “Ten minutes until warm up!” shouts the head coach of the team. You realize that you haven’t even had time to put on your swimsuit yet. You zip open your bag and grab your sleek swimsuit with a blue swizzle to resemble a stingray tail and run to the locker room to get

It’s a beautiful day at the beach, the sun is shining down on you as you float and drift on top of the waves.

The excessive growth of jellyfish swarm drastically lowers the population of fish eggs in the ecosystem. Because of this, fishermen lose millions of dollars. People in local communities are figuring out ways to solve this mass production.

A recent study by Facebook states that “Facebook estimates that between 5.5% and 11.2% of accounts are fake. ”(TNW), and this is just facebook. Out of all social media sites and other account based websites people are masking their identities every day. Having the option to change a person's identity, is the scariest thing in the world to me, and it's even more scary because the internet is a vast abyss that can be manipulated into anything anybody wants it to be. Physically, identities are fixed, but digitally they aren't but the users creation, whether that be factual identities or not.

Over time, people are able to develop their personalities and change the way they are towards others and themselves.

A documentary is an expository text that informs its audience about an issue person or event using visual and auditory conventions to convey a message. Documentaries are often used to reveal an unusual, interesting or unknown angle. Topics are limited only by one's imagination. The documentary Blackfish is the story of Tilikum, a captive killer whale that has taken the lives of several people, it underscores problems within the sea-park industry, man's relationship to nature, and how little has been learned about these highly intelligent mammals. This documentary was directed by Gabriela Cowperthwaite. The ideas that orcas are wild and unpredictable, Seaworld’s treatment of orcas are inhumane and Seaworld’s was negligent in their training of their trainers. These ideas are shown throughout the documentary as visual techniques of Celebrity figure, expert opinion, audio codes, the documentary technique of interviews, archival footage and written codes. I think these ideas in the documentary are quite true and are well proven throughout the documentary.

Ideas that are powerful effectively influence and evoke cognition of the audience, hence composers aim to present powerful ideas in their documentary. Blackfish is a documentary which concerns the captivity of Tilikum, an orca held by SeaWorld involved in the deaths of three individuals, and the consequences of keeping orcas in captivity. In the documentary "Blackfish" composed by Gabriela Cowperthwaite, the idea of animal cruelty is explored. Through various documentary and cinematic techniques and emotional appeals, Blackfish exemplifies their argument and engages its audience in the discussion of the Marine Park industry and the effect of animal conservation.

“Take your marks”, the referee said then boom as fast as lighting I heard the beep and leapt from the blocks and raced my heart out. As I raced I felt amazing hitting ever flip turn perfectly not missing a stroke and then I finished looked up and say I had done it. I beat the kid who said I was bad and couldn’t swim. We then all got out and I went over to congratulate him. We sho hands and said good job but that’s when I asked him why he had said those words. He didn’t know why he had done it. He apologized and said that he had underestimated me, and from this day on he was no longer so cocky, his temple had been crushed and he no longer underestimated me. So this shows and explains the morals of this story. You can have a different perspective on people or judge them in a wrong way. This person happened to look at me and think to himself that I was a bad swimmer, somebody who would never win, and somebody who would never beat him. He looked at me and judged me before he even knew if I was good or not. I beat him and proved to him that I wasn’t this “sucky swimmer”, and this is the story of when someone miss judged
