Extended Essay Subject: Biology HL How Does the Presence of Caffeine Affect the Growth of Bacteria of the Digestive System? Student Name: Bixiang (Sean) Cheng Session Number: 000537-0010 Supervisor: Ms Julie Cavell Word Count: 4000 Abstract Caffeine is the most widely consumed legal psychoactive drug across the world. It is widely used to ward off fatigue and increase focus. Although it is considered to be a harmless substance, and sometimes beneficial, it has been shown that caffeine has antibiotic properties against both beneficial and pathogenic bacteria. This means that regular caffeine consumers could be putting their health at risk by exposing their intestinal bacteria, which provide us with important nutrients, to the antibiotic properties of caffeine. As a result, caffeine consumers may be unknowingly depriving themselves of certain crucial nutrients such as vitamin K2, a substance important in the process of calcium absorption into the bones. This investigation aimed to determine the effect of caffeine on the growth of bacteria. The research question developed is: How Does the Presence of Caffeine Affect the Growth of Bacteria of the Digestive System?

The Black Cat free essay sample

The man I married was tender at heart and was particularly fond of animals. When he was a child, he was pampered with many different pets, and was at his happiest when feeding and taking care of them. However, his affection for animals grew as he got older and I noticed it. We acquired birds, gold fish, a nice dog, rabbits, a small monkey, and a cat named Pluto. Pluto was a beautiful, large, black cat and was my husband’s favorite pet and playmate. He would follow his only caretaker around the house and would even follow him out into the streets if he was allowed. Their friendship had last a few years, until he unfortunately became an alcoholic. Day by day, he grew more moody, irritable, and more regardless of others feelings. He began using vulgar language towards me and even started mistreating me. He even neglected his beloved pets when they got in his way. We will write a custom essay sample on The Black Cat or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Pluto, however, was an exception because my husband tried his best to restrain himself from ill-treating him. Nevertheless, eventually poor Pluto also began to feel his wrath. In the middle of one night, I had awoken and made my way out of our bedroom after noticing that my husband was still not home. I looked out the front window and saw him walking unsteadily in the direction of the house and our black cat making his way towards the drunken man. Suddenly, I witnessed him violently snatching Pluto and the frightened cat accidently biting his hand. In horror, I watched as my once-loving husband became possessed by anger. With malice showing in his eyes, he grabbed the unfortunate pet by the throat and pulled out his pocket knife. My hand rose to my mouth in fear and I gasped as the ill-fated cat had one of his eyes cut from his socket. With tears threatening to spill down my face, I hurriedly made my way back to the bedroom and feigned sleep. The last thing I wanted was to experience the other side of my husband’s rage. My thoughts prevented me from real sleep as I thought about how much the man that is currently unconscious on the couch has changed, considering everything that is now on his conscience. As expected, the cat slowly healed, but now the creature was petrified when my husband went anywhere near him. One morning, while making my way home rom the market, I noticed something hanging from the tree in front of our home. As I got closer, realization struck me and the groceries dropped out of my hands and on to the dirt path. There was Pluto hanging from a noose from a branch on the tree. I was frozen for what seemed to be hours, but were merely minutes, before I gathered myself and made my way into my house. Terrified by the cold blooded murder my husband committed, I decided not to say a word to him about anything. That very same night, I was awoken by my husband and looked around to find a fire blazing in every direction. As we were struggling to get out of our room, I saw a small black figure in the corner of my eye, later concluding that it was our precious cat that was thrown through the window by someone attempting to wake us. With much difficulty, my husband and I, along with our servant, escaped the flaming house, which would soon be in ruins. One day, as I was preparing dinner, my husband came home with a content face. That is when I noticed the large black cat purring and rubbing against his legs. My mood suddenly uplifted and I bent down to pet and caress it. This new pet automatically made itself at home, and it greatly reminded me of Pluto. It was almost as big as him and closely resembled him, except for a patch of white nearly covering its entire breast. Unfortunately, like Pluto, it also was deprived of an eye, and that made me fonder of it. It was very affectionate of my husband, and it seemed to bring back a bit of happiness into the household. The beautiful cat followed the same habits as Pluto had, including following its founder around. However, after a while I noticed my husband growing annoyed by it yet again. He tried his best to avoid it at all costs so he would not get the chance to strike and abuse it. My husband seemed to be somewhat frightened by the creature every time it would approach him and even when it would simply show love. After a while, he became very cold-hearted and forlorn, but I just remained quiet and patient. The old building in which we were forced to inhabit in replacement of our home had a cellar under it. This cellar contained coal and other questionable junk from past residents. One day, after my husband realized that we had run out of coal, I accompanied him down to the creepy room. As we made our way down, I noticed that the cat had followed us and swooped down to pet it before continuing behind my husband. Unfortunately, I did not notice the cat making its way past me and towards the man. Suddenly, the poor creature got in the way of the husband’s feet, almost throwing him headlong. The enraged man picked up an axe, but before he could do anything he would regret, I stopped his arm to thwart him from swinging towards the cat. Only after looking in his eyes, which were full of contempt and malice, did I realize my mistake. Everything slowed down as I saw a flash of the axe making its way towards me and finally coming in contact with my skull, making everything go dark.

She started the first women's movement, which was the most famous of all feminist movements.The other first woman to get a big idea is Elizabeth Cady Stanton, who led the first female college group that was called the Women's Christian Temperance Union.

The Autobiography My Place By Sally Morgan Explores Sallys Experien Es

The autobiography ?My Place' by Sally Morgan explores Sally's experiences in her own life, growing up in surburban Perth in the fifties and sixties. Through the memories and images of her childhood and adolescence, vauge hints and echoes begin to emerge, hidden knowledge is uncovered, and a fascinating story unfolds-a mystery of identity complete with clues and suggested solutions. There were many influences in Sally's life, the main ones were people she knew, places she went and events that took place at that particular place with that person. These influences were all revealed through the author's choice of words. The two most important figures in Sally's life were her mother (Gladis corooner) and her Nan (Daisy Corooner). Since her father was not around at all in her teenage years, which were her most critical years for a role model, she looked towards her mother for every answer. Her mother was kind and loving. Although, when Sally's father died Sally's mother had to work, so Sally's Nan became her new rolemodel. Sally's nan did not stay Sally's rolemodel for long, because as Sally grew older she realised that Nan and herself had not much in common. The only thing they really had in common was their love for nature. Both nan and Sally had a soft spot in their hearts for nature. When Sally was a small child, Nan would wake her up in the crisp of the morning to listen for the call of wild animals. Nan and Sally would sit for hours listening and waiting to hear those beautiful sounds of the Earth. This influenced Sally's life because later on in her life she became very loving towards nature an d any stray animal would find a home in their house. This was revealed through repetition because Sally Morgan constantly talked about the asapects of nature and Nan. Now with Sally's mother finding a job she had more money to spend so Sally's life became much more luxurious. Sally and her family enjoyed their time spent together. Sally believed that a families closeness towards eachother was very important. Sally's mother was an influence in Sally's life because Sally's mother was really the only female Sally could look up too. She could look up to Nan, but Nan and Sally had their differences. So Sally's mother had an important role in Sally's life because she helped Sally find her place and identity in life. This was revealed through Sally's repetition of the events which occured between Sally and her mother. From a very young age of five years old, Sally had a feeling she was remotly differently. "I was a grubby five year-old in a grubby environment" (p.11). She felt this way as she walked through the hospital which she described with all the negative thoughts she could think of. Sally felt different because she was full of secret fears. Fears because her father was always sick, always being assured that he would get better when Sally knew he would not. As time progressed she was enrolled into school. School was a turn around for Sally, as it opened up a new world, and she began to look at the world with new ideas and thoughts. She learnt to read, and by far, was one of the best readers in her class. Reading also opened a new window for her, but unfortunatly, her teacher Miss Glazberg was prejudice towards her, and shut that window. When Sally's mother asked that Sally be given a new book, Miss Glazberg refused for no other reason than prejudice. Miss Glazberg was too short-sighted in Sa lly's reading ability to realise that Sally should be given a new book. Miss Glazberg was not very appreciative towards Sally's reading ability. When Year 2 arrived, Sally started to get more of an idea that she was different. Sally couldn't prevent herself from wetting her pants one day. "You dirty, dirty, girl" Miss Roberts took her and pushed her out the door. This influenced her life in a negative way. Her attitude towards school took an even rapid downhill turn after that incident. It made her feel different from the other children in her class. She felt isolated and alone. This was revealed that
