Nutrition & Fetal Brain Development Critique
Words • 676
Pages • 3
The fetal brain starts developing at just 2 weeks after gestation, which is before most women even know they are pregnant. According to Carolyn Robbins (2018), poor maternal nutrition can be damaging to the unborn child's brain development. If a woman is planning to get pregnant or think they might be she should talk to her doctor and make sure that she is eating a healthy diet. Robbins discusses brain development, malnutrition and the effects of alcohol and folic acid…...
Brain Development and Play

Textbooks. Speeches. Blackboards. These were key elements used for education for many years. However, learning doesn’t have to be so rigid. Neuroscience has taught us of a learning method much more appropriate for children, known as play. The idea is that kids learn by engaging in actual activities. The reasoning behind this theory is that the act of play actually helps development of the brain. Children will gain much more by actively engaging in a project as apposed to just…...

An Overview of DNA Replication
Words • 1979
Pages • 8
Introduction The process of DNA (Deoxyribonucleic acid) replication plays a very imperative role in providing genetic continuity from one generation to the succeeding one. Knowledge of the structure of the DNA began in 1869, with the discovery of nucleic acids. An accurate model of the DNA molecule was presented in 1952 by Rosalind Franklin, Francis Crick and James Watson. To reproduce, a cell must copy and transmit its genetic information (DNA), to all of its progeny. To do so, the…...
The Facts About HIV/AIDS Within the African American Community

According to the Kaiser Family Foundation, "African Americans account for more than half of the 40,000 new HIV infections estimated to occur in the United States per year. Moreover, AIDS is the number one killer among Blacks between the ages of 25 and 44." This frightens me because my Uncle is HIV positive. Nevertheless, I believe that the reason why political figures, such as President Bush are not taking the HIV/AIDS epidemic seriously is because the disease is not prominent…...

Use of Drunk Stories by Authors
Words • 712
Pages • 3
Often times in literature, authors will illustrate the use and effects of alcohol to reflect the experiences that they had encountered within their own lives. Alcohol usually creates a distortion of reality and in some cases self-destructive behavior. Although alcohol can be problematic, it is also used in literature for entertainment purposes and makes things happen. In “The Swimmer“ by John Cheever and “The Drunkard” by Frank O’Connor, alcohol influences the characters and provokes problems within their lives involving relationships…...

About 3.8 billion years ago the first signs of life appeared on earth taking the form of very simple, small, single celled microorganisms. 1.8 billion Years after this, these cells became more and more complex, with the formation of internal structures called organelles, such as mitochondria. Moving 2 billion years further, the first multi-cellular organisms evolved and thus becoming the basis for most life on Earth as we know it today.[Mic09). Ever imagined your ancestor being some cell 'living' in…...

One of man s greatest attributes is the ability to imagine. No other creature could make mental images of how reality might be, nor invision a part of the future. We make theories based on how things could have been or might be in order to quench our thirst for curiosity. One of these theories is the theory of evolution. This theory, according to many, answers the question, Where do we come from? This essay will determine that the theories…...

Modification of Enzyme Function in Potato Peel Catalase 
Words • 2231
Pages • 9
Abstract Catalase is an important enzyme in the cytoplasm of most living cells used to control and lower the build-up of hydrogen peroxide (H2O2), its substrate, by converting it into hydrogen and oxygen molecules. This reaction’s speed, however, is variable to different environmental factors that may affect catalase’s reaction (Mykles et al 2018). This experiment attempts to understand the different ways velocity in a catalase reaction, found in potato peels, can be affected based on different atmospheres. Since catalase enzyme…...
Experiment with Potato and Enzyme
Words • 1410

Materials and Methods Before we were able to begin with any experiments, the skin of several potatoes had to be extracted and then juiced. To juice the potatoes, about 4 mL of 7.2 pH citrate buffer had to be added to the potatoes peels in the juicer. After the peels and buffer were relatively liquified, the solution was filtered using cheesecloth until we were left with 20 mLs of juice with no organic matter. From this point forward everyone should…...

Introduction: As you read this, there are thousands of chemical reactions occurring in your body at extremely fast rates. But when the speed of these chemical reactions is tested in a lab—instead of a body—these reactions are noticeably much slower. One might question, why is there a difference in speed? What does a lab environment lack that our body does not? The answer to these questions would be: enzymes. An enzyme is a biological substance that acts as a catalyst…...

Genetic engineering, also known as genetic manipulation, is a controversial topic. A Harvard study states that around 10,000 medical conditions are related to genetic mutations. Technologies like CRISPR Cas9 and prime editing could potentially decrease those numbers. These same technologies could be used to improve medical treatments and possibly eliminate particular genetic diseases. Many believe that editing the genes of sperm, eggs, or embryos is a line science should not cross due to the fact it may result in new…...

Photosynthesis Process in Plants
Words • 371
Pages • 2
What happens to carbon atom during photosynthesis?(Light dependent reactions) ·Light depended reactions occur inside the thylakoids. When the chlorophyll molecules absorb sunlight they give off high energy electrons. They move through a series of electron carrier proteins called electron transport chains in the thylakoid membrane. The proteins in the electron transport chain use the energy to pump hydrogen ions into the thylakoid from the surrounding stroma. The stroma is the gel like fluid inside the chloroplast. The hydrogen ions pumped…...

Investigation to find out how light intensity effects the rate of photosynthesis
Words • 3198
Pages • 13
Flowering plants, like all living organisms, need a supply of food. They need it as a source of energy in respiration and they need it as raw material for growth and repair. Animals and most micro- organisms get their food in an organic form: they eat products from other organisms (such as fruit and eggs) or, nowadays, the organic substances made in laboratories and factories. Animals and the microorganisms that do this are called consumers. Due to the flowering plants…...

Before starting my investigation on how temperature affects the rate of photosynthesis I carried out some research into photosynthesis. From this initial research I made a prediction based on the evidence that I found about the enzyme rubisco that is used in the dark stages of photosynthesis, and also on the limiting factors of light intensity, carbon dioxide concentration and temperature. I then went on to carrying out a preliminary experiment from which I learnt the factors that made the…...
The Rate of Photosynthesis on Plants
Words • 224
Pages • 1
When organisms like cyanobacteria, algae, and primarily green plants use the energy from light and turn this energy into carbon dioxide, or water into oxygen and sugar, this process is called photosynthesis. The equation for photosynthesis is 6C02 +6H20+light energyв†’ C6H12O6 + 6O2 (Newton, 2019). The sugar created is stored in the starch. Starch is then used as fuel for plants, these are heterotrophs and autotrophs (Newton, 2019). In photosynthesis, there are two stages that are light-dependent. Light-dependent means that…...
