Viruses are infective agents that are unable to support themselves and rely on other hosts for survival. Although they are not a living thing, viruses are able to infect humans, plants, bacterias etc. Depending on the type of virus, they target a specific organ or type of cells and inject their DNA or RNA in the cell to reorganize the genetic material of the cell. The cell then follows the new DNA instruction and produces more viral viruses. The adenoviridae, better known as adenoviruses, are a…

behind him,” writes Skloot in the prologue of her book “The Immortal Life of Henrietta Lacks.” “Henrietta died in 1951 from a vicious case of cervical cancer, he told us. But before she died, a surgeon took samples of her tumor and put them in a petri dish. Scientists had been trying to keep human cells alive in culture for decades, but they all eventually died. Henrietta’s were different: they reproduced an entire generation every twenty-four hours, and they never stopped. They became the…

this scenario: You are standing in a room. On one side of the room, a petri dish with a fertilized egg is falling off of a table, and on the other side a newborn child is also falling as the same time. Which side of the room would you chose? The answer for most is difficult, but obvious. The newborn child takes priority. Why is this? If a fetus is considered a human being right full rights and power, could one catch either dish or baby and feel the same amount of guilt and consequences? No; this…

Introduction: In this Biology class, we want to find which place is dirtiest place in the school. So, my group Locker D2165, Elijah's left boot, Boys sink plug puller, Small spot under Gregor’s castle, Mrs. Pearce closest table to her desk, On the right marker tray of Ms.Pearce’s out of by cell phone jail, Boys bathroom behind toilet floor crease, Stair hand rail by library top rail. Hypothesis: My hypothesis is that the more commonly used and more commonly touched items in the school will…

Scientists are developing ways to edit the DNA of tomorrow’s children. In the short story “Flowers For Algernon”, by Daniel Keyes, there is an intellectually disabled man named Charlie Gordon that is also going to be operated on to promote his intelligence. As informed scientists are developing ways to edit the DNA of babies. That means that people are making their babies with requested traits: intelligence, eye color, athleticism, and disease prevention. They are known as designer babies. As…

The Truth Behind Animal Testing 95% of animals used in experiments are not protected by the Animal Welfare Act. These animals are more likely to be abused because they have no protection. 26 million animals are used every year in the US for commercial and scientific testing. According to the Humane Society International, animals that are experimented on are subject to force feeding, inhalation, food and water deprivation, lengthened periods of physical restraint, and infliction of…

harmful to some species of animals but, to humans, proves to be extremely useful. Finally, not only can we say that animal testing is ineffective, but we can say that alternatives can produce more relevant results; as testing in a glass, such as a petri dish, can use human cells (“Animal Testing”). As a result, the use of human cells would be able to better predict a drug’s effect on a human than, say, an animal…

One of the most debated topics in science is the use embryonic stem cells in scientific research. The ethical debate surrounding embryonic stem cell research comes down to two core values that we want to uphold: the alleviation of human suffering and preserving the inherent value of human life. Embryonic stem cell research is such a tricky topic because it requires us to choose between these two core values. We cannot uphold both values because the alleviation of suffering in this case is…

Cancer is a disease that have been infecting people for centuries. It is also the leading cause of disease worldwide. According to the cancer research group in the uk, in the year 2012 there was an estimate of 14.1 million new cases of cancer. This was split 53% in males and 47% in females. Several cancer types exists and I will be focusing on breast cancer. In the years 2013 the American Cancer Society stated that there was 64,640 new in Situ cases and 232,340 new invasive cases. In situ cancer…

Jada Davis Mrs. Gomez English-5th period 26 March 2024 I need a TITLE. Manipulated, harassed, and thrown into unsafe experiences; we need to stop testing on animals. We are putting them through way more than we should, and that needs to end. We treat them like they’re objects to be used, but they are living beings. Research on animals has been practiced since around 500 BC. Animals are used to help improve medical treatments, determine toxicity in medications, and check safety in human products…
