Animal behavior, by definition, is the behavior within all the living animals. However, what is exactly called behavior? Does each individual animal possess unique behavior regard any stimuli? Do all the animals born with the unique behaviors? All the curiosities trigger the study of behaviors, which are known as ethology. Behavior is the action that carried out by animals in response of environmental stimulus. Ethologists group all the behaviors into two categories: learned behaviors, are those…

interactions form an ecosystem. The two main processes of an ecosystem are the recycling of chemical nutrients and the flow of energy. Cells are a component of all living organisms and essentially are life’s basic unit of structure and function. Every cell is enclosed by a membrane which regulates materials passing between the cell and its surroundings. In addition, every cell uses DNA to determine its genetic information, which is the inheritance of genes from parent to offspring. Gregor…

academic researcher in beta-cell proliferation field. I started early in my fellowship training to explore that field by studying the prognosis of total pancreatectomy with auto islet cell transplantation in children with chronic pancreatitis. Successful completion of the project was the starting point that prompted me to choose Dr. George Gittes, a well-known expert in that field to be my mentor. My long-term goal is to become an independent researcher in the field of beta cell proliferation,…

of gene families. And fortunately, their genes are easier to identify and sequence than our. Additionally, biological processes of human and fruit fly are also similar (Hughes, 2012). Thanks to that, we are able to study human behavior and basic biology using these…

Darwin’s theory of evolution is an idea that all living organisms are related and have a common ancestor. His broad theory speculates that progression of life from non-living and emphasizes an all in all realistic “descent with modification”. In other words, complicated creatures emerged from uncomplicated creatures consistently over time. This meaning stray genetic mutations happen in an organism’s genetic code. These mutations, which are useful, are retained as they help in survival, also…

Biology is the science of life or living matter in all forms and phenomena, especially with reference to origin, growth, reproduction, structure and behavior. Living beings have the desire to discover who they truly are and how they came to be the person that they are today. Many people have specific beliefs in an ultimate being that rules over all else, but most of these beliefs cannot be proven. The study of biology is based upon facts and hypotheses that can be tested and supported. Without…

proven an essential gene to neural development and cell differentiation. Mutations in this gene absolutely develop a severe phenotype, as the sensorial system plays an important role in the animal body. Future researches with Drop gene could establish a treatment for craniosynostosis or relieve the severe symptoms of this disorder (Mozer, 2001). This big similarity gives an opportunity to researchers discoverer mutations in genes related to human biology, such as neural development, eye…

The film “Pharm” is a documentary movie that explores the world of genetics and evolution. According to Darwin, evolution refers to any living organism that has developed and diversifies over extended periods of time. Genetics is the branch of biology that studies the genes, which are units of heredity that determine what and how proteins are made, therefore are responsible for what characteristic get passed onto the next generation. Evolution involves many mechanisms besides natural selection,…

Matthaei. They accomplished this in a series of experiments called ‘cell-free. In this experiment, all the things needed for protein synthesis were added to make a very simple nucleic acid in a test tube. They composed a chain of only one single repeated letter: the nucleotide uracil (UUU). Nirenberg and Matthaei’s experiment…

I enjoy all of my A-level subjects, and I want to continue with as many as possible, so I am applying for Natural Sciences. I am eager to study in more depth the areas that I have found interesting, as well as to explore new topics. For me, Human Biology currently stands out as the most exciting field, as I can see at first hand its applications and effects, and constant developments mean there is always something new to learn. It is this dynamic side of science which I want to be involved in.…
