Cells Research Assignment I. Define the following terms CELL NOUN The (usually) microscopic structure, known as a cell. Is the functional and biological unit of all organisms (life forms). INFERENCE NOUN Is a conclusion, idea and/or opinion that is reached on evidence, reasoning and the information that you have. It is simply, an educated guess. Synonyms implication, interpretation, deduction, reasoning, speculation, presumption, assumption. OBSERVATION NOUN 1. An act of viewing,…

In 2004, the National Health and Medical Research Council (‘NHMRC’) banned sex selection on moral and social grounds, except in the case of a serious genetic condition. However, recent debates in Australia have led the NHMRC to consider the prospect of lifting the life ban. It is inherent in such a culturally diverse society that the public cannot reach one consensus. While some believe that sex selection is unethical for ‘moral’ purposes, others believe that it is an ethical means of hindering…

deoxyribonucleic acid, is the stuff in humans and almost all other organisms. About every cell in you and everyone else's body has the same DNA. DNA is usually located in the cell nucleus (nuclear DNA),however small amounts of DNA can be found in the mitochondria (mitochondrial DNA or mtDNA). The DNA has information stored as a code created by four chemical bases: adenine (A), cytosine (C), guanine (G), and thymine (T). Each base is connected to a sugar molecule and phosphate molecule. All…

This means that to measure bacteria a person will have to count the cell numbers not measure the size of the cell. According to Frank O’Mahony, bacterial growth is affected mostly by temperature, nutrient, water supply, oxygen supply, and the acidity of the medium, which leads to the question of could vibrations from music affect the bacterial…

Summary/Response: “Human Reproductive Cloning: A Conflict of Liberties.” In this article “Human Reproductive Cloning: A Conflict of Liberties,” Joyce C. Havstad’s conflict is if cloning becomes safe and reliable, people should be able to have reproductive freedom. The author explained that promoters of human cloning know that it may lead to harmful characteristics. Instead of positively promoting human cloning they explain the causes and effects that could take place. They do strive to allow…

into the sample wells with a couple of sample wells left in between each of them in order to more easily compare the end results and avoid collision of substances. After making sure that each of the gels were transferred to the correct electrophoretic cell, the chamber was to be electrophoresed for 8 minutes before it was to be turned off. The location of each of the four proteins was to be recorded compared to the insertion point. Electrophoresis was to be continued if bromophenol blue (within…

The Brave New World book was written by Aldous Huxley where he created and illustrated a fictional world that everyone is cloned, classified since birth (Alpha, beta, gamma, delta, and epsilon) and finally everyone can promiscuous anyone. In Huxley's argument, people from the book have similarities and differences compared to our society. Let's first talk about the similarities where people from the Brave New World book are similar to our society from the following points. Firstly, the…

The Epigenetics Revolution: How Modern Biology Is Rewriting Our Understanding of Genetics, Disease, and Inheritance, written by Nessa Carey, is a uniquely constructed introduction to the world of epigenetics. Regardless of its recent emergence in science, Carey articulately ties in both historical context and scientific evidence to outline and support the developing knowledge of epigenetics. She uses scientific studies, advances, and even possible future developments of the field to engage and…

There are numerous differences between flatworms, roundworms, and segmented worms, both externally and internally. Flatworms is part of the phylum named Platyhelminthes, that is part of kingdom Animalia. They are usually soft and flat, and they also have internal organ systems and tissues. Flatworms are the simplest organisms that have three embryonic germ layers, are bilaterally symmetrical, and have the feature of cephalization. Cephalization is the concentration of sensory organs and some…

are created to lock onto a specific type of cell membrane receptor, called the alpha-dystroglycan receptor. The main targets of the Lassa virus are dendritic cells and endothelial cells. Dendritic cells are cells that live in the immune system of mammals, and they are responsible for managing a molecule known as antigen. Antigen is a very important molecule that is responsible for activating an immune response for its host. Endothelial cells are cells that line the surface of blood vessels. Upon…
