The investigation which I am going to be carrying out is to estimate the concentration of the cytoplasm of potato cells. I will do this by investigating using the movement in and out of the potato cells through Osmosis. Osmosis is the process whereby water molecules pass through a semi-permeable membrane from a high concentration […]

Anticipating the blue waters of the Gulf and hoping to enjoy a nice sunny day, but instead it has been ruined by the reddish-brown color that now appears on select areas close to the shore and there are dead fish floating on the surface. Soon after, the overwhelming feelings of a cough, watery eyes, and […]

Modern medicine is filled with drugs that have been derived from deadly poisons. The potency of these poisons in nature is no accident; each is a part of the organism’s defence and predatory mechanisms. Animal venom’s make a particularly good source of potential drugs as they are designed to kill or immobilise prey. Many poisons […]

The subject I am studying is the presence of microorganisms in milk, specifically from ‘Farm to Fork’. The ongoing argument between raw and pasteurized milk is especially significant in rural areas like mine. In Ireland, selling unpasteurized milk has been illegal since 1997. My research will focus on how microorganism contamination occurs throughout the entire […]

The relationship between gender and biology is an increasingly complex issue. This essay will argue that traditionally in Western Culture, biology is seen as an important factor in defining gender; but that the emergence of a greater universal cultural awareness, recent philosophical, psychological and legal debate has lessened the biological emphasis in determining gender. It […]

 Introduction Over the course of the last few weeks, we conducted experiments in which our goal was to successfully ligate EGFP cDNA into pET41a(+) in order to transform our recombinant expression plasmids into clones of E. coli. After growing these cultures on varieties of agar plates, we attempted to isolate our recombinant plasmid DNA and […]

The study of gene expression provides invaluable insight into an organism’s structure and function; how it is that from a mere embryo genes can control which cells, tissues, organs and limbs will develop, providing the organism with the inherited traits that specifically adapt it to its forthcoming environment. Mutations of particular genes are sometimes associated […]

Abstract Introduction The field of Genetic Engineering is complex and controversial, involving ethical debates and exciting scientific advancements. It primarily revolves around DNA, or Deoxyribonucleic acid, which forms the basic building blocks of all living organisms. Understanding DNA is essential for genetic engineering and altering DNA. Those unfamiliar with genetic engineering or designer babies may […]

A. DNA molecules are nucleotides which are the A, G, C, T. A long series of the nucleotide makes up the genes. The sequence of the nucleotides determines each of our 20,000 different genes. Every 3 nucleotides codes are for a specific amino acid. The amino acid sequence determines what protein will be made. The […]

Chapter 1 How do find yourself when standing in front of the mirror? Did you ever care to check even the tiniest point and stain in your face? How about pimples? Does it make you feel terrified and irritable? Acne is one of those likewise terrifying moment which is widespread and goes through most of […]

The text presents experiments and observations on simple diffusion, dialysis, and facilitated diffusion. It provides the molecular weights of Na+ and Cl- and their ability to pass through membranes with different MWCOs. Certain MWCOs allow for diffusion from the left beaker to the right beaker, while smaller materials do not diffuse. Urea concentration is equally […]

The report includes the analysis of physical development, along with intellectual, emotional, and social developments at all stages of life. The following text explains possible events that may occur during different stages of Chelsea O’Mahony’s life, but these events can also happen to anyone. The process starts with conception, which initiates cellular development. During pregnancy, […]

Biology as a natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy. It is a vast subject containing many subdivisions, topics, and disciplines. Among the most important topics as contained in Biology are five unifying principles that can be said to be the […]

Human Fertilisation and Development Each day cute little babies are born into this world and being dazzled by their beauty we forget all about the long complicating process that took place which made it possible to have a baby. Therefore in my essay I am going to discuss the human reproductive cell, fertilisation and the […]

Down syndrome is the most common cause of mental retardation. It is caused by the presence of an extra chromosome. Chromosomes contain sequences of DNA called genes that represent the genetic information that exists within a cell. Twenty-three distinctive pairs of chromosomes which is 46 in total. They are located within the nucleus (a region […]

The decline of all major pollinators in the Northern Hemisphere, such as bats, butterflies and especially bees are likely to result in negative implications around the globe including South Africa. Bees are the most commonly chosen pollinators around the globe although there are many other capable insects. As early as the 1900’s, colony collapses have […]

Introduction For about eighty years now, people assert that life began in a primordial soup of organic molecules prior to evolving out of the ocean many years later. Today claims that the chemical energy of the earth from hydrothermal vents in the ocean floor has overturned the theory of primordial soup. Discussion The primordial soup […]

High levels of alcohol consumption among women have been on the rise in this century. Most of the reasons that lead to this are the desire to minimize on their stress levels, the high cost of living, family issues, and just for entertainment, especially among teenagers. The perceived long term effects of such excessive alcohol […]

Notes Ants are powerful predators: Ants may live in colonies of up to 100 thousand and like a human city they need constant supply of food. They kill large insects and carry them back to base. In one year a single colony consumes over 10 million insects. They consume more meat than lions, tigers, and […]

Homosexuality is the result of genetics and brain formation and is not a choice or effect of human nurturing. The debate of this topic has occurred for many years in many cultures. Brain formation as early as fetal growth in utero determines sexuality in proven studies. Genetic research shows that homosexuality linked through specific chromosome […]
