Zebra Fish Lab Report

This lab was conducted with the purpose of confirming the trait of homeostasis among goldfish. During the experiment, it was recorded that the fish would increase gill movement when placed in colder water two out of the three trials. However, the results showed no significant difference in gill movement in various temperatures of water. This has very little effect on the broad field of science since our only three trials were performed and may have included human error in the trials.

At the conclusion of the experiment, the two hypotheses were reviewed. Because the water temperature did affect the normal respiration patterns of the goldfish, the null hypothesis was disregarded and the alternative hypothesis was accepted. From the results of this experiment, it was concluded that although other environmental factors could play

Lithium chloride (LiCl), is an ionic compound used in medication for affective psychological disorders. LiCl has also been linked to problems with the development of cardiac and nervous systems in vertebrates. The experiment proposed will investigate the effects of different concentrations of lithium chloride upon embryo development in vertebrates, using Zebrafish as a model vertebrate organism. Zebrafish embryos will be used, as they are aquatic, which allows for convenient administration of LiCl solution.

The objective of the lab was to analyze the formation of pelvic structures from two populations of stickleback fish collected from two different lakes. This was done in order to formulate a question based on observable phenotypic differences in twenty specimens from two different lake populations. Careful measurements were taken including the lateral plate, pelvic girdle expression, and body depth sizes. The purpose of the research was to formulate a question and develop a hypothesis based on the variations observed between several selections of populations, in order to gain a better understanding of evolution and natural selection. The data collected was used along with information about the lakes to suggest possible environmental factors

In this experiment, an oxygen-measuring probe was attached to an oxygen chamber in order to quantify oxygen consumption rate, which served as a substitute measure for metabolic rate. The oxygen-measuring probe provided real-time measurements of dissolved oxygen (DO) concentration present in the chamber water. The oxygen chamber was sealed to create a closed system so that over time, the oxygen levels would decrease as the goldfish respired and consumed the oxygen present in the water. The software LoggerLite was used to record real-time DO concentration measurements.

An association between enzyme production, gene copy number, and gene evolution was explored by conducting analysis of the salivary amylase enzyme, AMY1A gene copy number, and the ancestral starch consumption in Homo Sapiens (Tracey 2017, p.22). It was hypothesized that the relative amount of starch consumption was very high for my personal ancestral diet, thus my AMY1 diploid gene copy number in my genome and salivary amylase concentration would be significantly higher than the population mean. With a population of 28 subjects (n=28), individual saliva samples were collected and compared to a calibration curve to determine the approximate amylase concentration by analyzing absorbance values. Individual samples of buccal cheek cells were

A male Betta is to be placed on the opposite side of the bowl, so that they can see each other but no contact. The fish were observed for two minutes. After the two minutes passed, the barrier was lifted and observations were recorded for one minute before the male was removed from the bowl. This was then repeated with the female Betta. These two constitute one trial. There was a total of three trials, so both the male and female were in the primary bowl thrice

Most people would not appreciate a stranger walking into their home unannounced, taking their food, and making themselves at home. That is exactly what lionfish are doing along the Florida coastline. Lionfish are an invasive species that need to be contained. The reefs that they consistently invade off of the coast of the Florida are not the lionfish's natural habitat. This invasive species takes shelter and resources out of the reef that other species need to survive, and they destroy the environment around them. Humans have complicated the balance of the ecosystem by introducing lionfish, and now they need to help rectify the situation.

Crayfish are crustaceans that are a part of the phylum arthropoda. Similar to the lobster, an organism within the same phylum, crayfish breathe via feathered gills. It is the use of these gills that allows oxygen uptake and thus the ability to survive in freshwater environments.

The first time I felt the recoil of a shotgun coincide with the simultaneous drop and flop of a turkey I knew I was hooked. This was all the way back in the fall of 2005 when I shot my very first turkey alongside my father. That day started an addiction that has since intensified and spread to not only turkeys but almost all of Missouri's highly sought after species. Hunting, conservation, and the great outdoors have always been embedded in the hearts of my family. I am no different and plan to dedicate my life to Missouri’s wildlife the same way they have.

Navigating the World’s oceans is a difficult task, finding a small place where you were born two years earlier without any navigational tools at all is impossible for most. Pink Salmon are an incredible species capable of this and so much more, but now they are faced with their greatest challenge to date. Pink salmon must somehow survive the changing chemistry due to climate change that is altering their environment, and poses the greatest risk the species will likely ever face.

The ecosystem with which the simulation is being done is an aquatic ecosystem. This specific ecosystem is home to producers such as: black pine, coral weed, and nori seaweed. Stationary consumers like acorn barnacles, gooseneck barnacles, and mussels are also present. Mobile consumers such as chitin, starfish, and whelk. The invasive mobile consumer is the green crab. Animals such as starfish compete with others like green crabs for mussels. Starfish and whelk prey on and also compete for the gooseneck barnacle. Whelk and green crab also compete for the acorn barnacles. The competition between starfish and green crab over mussels is what led me to my hypothesis as the mussel is one of the largest secondary consumers in terms

When the freezing point for water is 32 degrees fahrenheit (0 degrees celsius) what happens to life beneath the ocean when temperatures plummet in Antarctica? There has been recent discoveries of antifreeze proteins in Antarctic fish. Dr. Arthur DeVries was the first to discover such proteins, in the 1960s, and describe how they bind in the blood of fish to ice crystals and prevent the fish from being frozen.

Zebra mussels are an extremely large species of mussels that are notorious for causing problems for animals, sea creatures, and even humans. They have the ability to cling and adhere to any man made, living, natural object, or creature when placed or growing in the acceptable conditions and habitat. Zebra mussels have many characteristics, traits, and ways of thriving, surviving, and of course, unknowingly creating problems for most of life on Earth. These fascinating and compelling critters have an intriguing story to tell about how they reached the U.S. and why they generate complications and issues for mankind and our environment.

Conclusively, after completing this lab I reject the original hypothesis stating that the higher the temperature of the individual’s hand the more the Mysterious Red Fish will react. The inconsistency in the data recorded throughout the lab led me to believe that it is incorrect. To complete our quantitative data we did 3 trials. In those trials my partners and I measured the length of the Mysterious red Fish when it was lying flat and then measured it again after it reacted on our hands. The data proved to be unreliable, when the fish was on Alex’s hand 4cm of the 9.1cm long fish was in contact with her hand in the first trial. In the second trial, it went down to 3.5cm on her hand and went up to 6cm in the last trial. Furthermore Erica’s
