Temperature, pH, and Salinity as Limiting Factors Affecting Growth, Development, and Survival of Rainbow Fishes and Corn Seeds Brendalyn R. Basilan INTRODUCTION Environment should be suitable for the organisms to stay fit and survive. These environmental factors should meet the minimum and maximum criteria of what life requirements to satisfy the organisms’ state of existence. The environmental influences that coerce the increase of populations and have the ability to object their capability…

To start this experiment, two microcentrifuge tubes were exposed to different ingredients. One was labeled “+DNA,” the other with “-DNA.” They were both filled with different bacteria. More specifically, the “+DNA” tube had pGFP in it and included a plasmid. Included on that plasmid were two genes: gfp (gene for green fluorescent protein) and an ampicillin resistant gene. The gfp gene makes cells glow and the resistant gene fights against ampicillin, which kills cells. This plasmid DNA was…

In one of the darker times in the world, humans were locked up and experimented on with no say-so as to what happened in their lives. This happened during the Holocaust. This is how millions of animals feel everyday in labs all over the world; so why are these cruel methods still actively used? Alternative methods are readily available, so why do we still practice animal testing? I feel most, if not all, forms of animal testing are cruel, inaccurate, and unnecessary. Most forms, if not every…

method of using regeneration to regrow parts of their bodies when severed and separated from the other half. In order to conduct this experiment, a small planarian worm was obtained from a glass of spring water using a pipette, and then placed into a petri dish filled with enough spring water to keep the worm alive (But not enough that could allow the worms to escape). Then, using a razor blade, the planarian worm was cut in half to produce two worms (in my case specifically, separating it into…

Audience Analysis This paper targets students who have ill family member and animal lovers. Since I am exploring about the topic of animal testing that has been very controversial, my primary audience, UMD students, would be able to actively be a part of this topic to come up with their own opinion. Both my primary and secondary audiences must have their own background information and idea of why or why not people should conduct animal testing. To reach my audience, I can publish this online on…

House (with Denzel Washington and Ryan Reynolds), gets to add a horror element thanks to the alien on board. This idea may not be original, with plenty of references to John Carpenter’s The Thing (especially in a nerve-shredding sequence involving a petri dish), but everything is enhanced with a flourish and panache that elevates what could have otherwise been a predictable genre film. The setting is a close approximation of the present day, and the characters react in an entirely relatable…

called Opium in a large property called the Alacrán Estate. Opium is in a strip of poppy fields in between the USA and what used to be called Mexico. Matteo Alacrán (Matt) is a clone that was harvested from the womb of a cow after being made in a petri dish. Matt is a clone of El Patrón the lord of the country, Opium. Matt was born from a cow womb, but does not know that so he lives with Celia one of the maids for the Alacrán estate. One day Matt meets two kids who he later identifies as Steven…

Germination is the process in which a plant stems from a seed, and it is fundamental in the development of plants. There are factors that go into how a seed will germinate, one of the most important being temperature. It is said that temperature is an environmental factor that affects germination. Temperature can affect the percent and rate of germination in at least three different ways. The first being that since seeds deteriorate, unless germinated, and the rate of deterioration depends…

collected at the right time. An ultrasound probe inserted into the vagina with a fine needle is how the eggs are collected (Better Health, 2014). In standard IVF, a few hours after the eggs are collected, sperm is collected and mixed with the eggs on a petri dish, where one sperm is directly injected into the cytoplasm of each egg in intracytoplasmic sperm injection treatment. If an egg is fertilised by the sperm, it is kept in an incubator for several days while the pre-embryo grows. Once the…

Based on personal experience, I am surprised that some plant based foods are surprisingly delicious. However, it is not as delicious as meat. Personally, a vegetable dish is taste way better when it is mixed with meat that a vegetable only dish. It is logical to choose the tastier one because the taste stimulates the appetite. Lastly, we exploit animals. We domesticated animals to help us with our needs. We utilize the scent detection of dogs to search…
