Zebrafish Synthesis 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.

embryos through certain environments in order for each one to adapt to a job already determined

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

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.

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.

This experiment began on the first day of lab by planting 12 total seeds from the F1 generation in six individual cells. Potting soil was added until each cell was a little

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.

The sixth lab I completed in Biology 101 taught me how autotrophs (self-feeders) and heterotrophs (other-feeders) make organic food molecules by using photosynthesis. Photosynthesis uses the energy from the sun and it is captured and stored in the chemical bonds of organic molecules. The sunlight consists of different wavelengths of light. In plant chloroplasts, they have different pigments that capture different wavelengths of light. Light capturing pigments in green plants are called chlorophylls and these absorb all the colors of light except green, which is mostly reflected. To separate molecules from each other according to their solubility in a particular solvent is done by the process of chromatography. This basically means that polar

Alexis Bonogofsky wrote about “reports of dead fish floating and collecting on the banks of the iconic Yellowstone River began coming into Montana Fish, Wildlife and Parks (FWP) in early August. The Yellowstone flows for 692 miles from Absaroka mountain range in Wyoming, through Yellowstone National Park, into the prairies of eastern Montana and finally, the Missouri River.

Antidepressants are detrimental to shellfish livening in the lakes because selective serotonin reuptake inhibitors that the chemicals’ contain affect their spawning and natural behaviors. Antiepileptic drugs could trigger extensive apoptosis in the developing brains of humans leading to neurodegeneration ("Pharmaceuticals and Personal Care Products (PPCPs) "). Calcium-channel blockers also affect shellfish that use calcium to make their shells ("Pharmaceuticals and Personal Care Products (PPCPs)

Human embryonic stem cells (ESCs) are pluripotent cells isolated from blastocysts, and are highly useful in studying human development (Itzkovitz-Eldor et al., 2000 p. 88). Although the National Institute of Health states that “it is not known if iPSCs and embryonic stem cells differ in clinically significant ways”, iPSCs are already being used to achieve the same results as ESCs in some applications without the use of embryos, removing the ethical concern associated with ESCs (National Institutes of Health, 2009). ESCs are capable of differentiating into all cell types, and can be used as a source of differentiated cells. In the report by Itskovitz-Eldor et al., they discuss the induced differentiation of ESCs in suspension into embryoid bodies, including the three embryonic germ layers. The authors state that “the ability to induce formation of human embryoid bodies that contain cells of neuronal, hematopoietic and cardiac origins will be useful in studying early human embryonic development” (Itzkovitz-Eldor et al., 2000 p. 88).

Model organisms are used to study embryonic development for several reasons. These organisms have shared characteristics including short life spans and generation
