Cell biology

Recent technological advances in biology have prompted me to want to study the subject as an undergraduate. I have been drawn to how the world works and what everything is made up of since secondary school, but in recent months my focus has shifted specifically towards the study of genetics. A wide and varied subject, ranging from eugenics and the ethical considerations of genetically engineering organisms, and to the more recent scientific breakthroughs in said area of study, the study of…

pathway is a chain of proteins in the cell that relays an extracellular signal from the Ras protein to the DNA in the nucleus of the cell. This pathway consists of multiple phosphorylations as MAPKKK phosphorylates and activates MAPKK which then phosphorylates and activates MAPK. At the end of this cascade, MAPK phosphorylates various effector proteins (Alberts, 557). This signaling pathway plays an important role in cells as it results in complex changes in cell decisions and behaviors such…

SCIENCE ENGINEERING TECHNOLOGY MATHEMATICS By Teanah Bautista and Izak Ford BIOLOGY OF HEARING The hearing is a quite a significant piece of creation used by humans. The complex organization of bones, hair, and cells it captures vibrated sound waves and processes to the brain. With everything happening almost instantly. But it's not as easy as it sounds. The sound is invisible vibrated particles through the air. The moving vibrations cause the air around to also vibrate creating sound waves…

The biological cell, as a metaphor for understanding disability, permits a dialect perspective of the body: as a construct socially negotiated between the natural and behavioural sciences. The "pathology" of disability is not located within the individual's body; rather, it is established as a "pathogenic" force of language characteristics of the cultural body. What can be found in the body of society is a system producing embodiments of engagement : social structures promoting the image of…

can fail us. Studying biology at an undergraduate level will allow me to grasp a deeper understanding as to why this happens, as well as develop my existing knowledge of the mechanisms involved in keeping humans alive. A-level biology has provided me with a broad spectrum of knowledge; topics outlining the function of the body, such as the circulatory system and the immune system, have further stimulated my desire to pursue degree level study. Whilst studying A-level biology, I have improved my…

In modern molecular biology and genetics, the genome is the genetic material of an organism. It consists of DNA (or RNA in RNA viruses). The genome includes both the genes and the non-coding sequences of the DNA/RNA. Understanding Human Genetic Variation Genetics is the scientific study of inherited variation. Human genetics, then, is the scientific study of inherited human variation. We study genetic material due to following reasons; 1. One reason is simply an interest in better understanding…

Vertebrate Histology (BIOLOGY 364) Fall 2015 Lecture Final (Take-home) A. Pick 3 of the following and argue that the following are either “adaptive” or necessary for survival, homeostasis, and/or reproduction: 1. Adluminal compartment of seminiferous tubules • The adluminal compartment is made up of spermatocytes, spermatozoa and spermatids. The compartment is considered a tight-junction. This tight-junction is said to be a blood-testicle-barrier. This means the…

Kaitlyn Staub Mr. G Biology Honors 4 January 2016 Title The Effect of Different Music Genres on the Growth of the Bacteria Serratia marcescens Introduction Exploring the question of does music affect bacterial growth requires much research. The purpose of answering this question is to figure out how to slow down bacterial growth by music. Also, if needed, the purpose is to figure out how to speed up bacterial growth through music. The hypothesis is that if the bacteria Serratia marcescens…

1. Explain how cells specialize to form specific tissue and organs. Cells specialize to form specific tissue and organs by stem cells being able to develop into every type of cell in the body and eventually recreate a person’s tissues. With organs, after you gather the cells which can be from the patient’s own organs you have to go towards how they grow and specialise. The cells need to be put in the right environment, and exposed to the forces that they would normally experience in the body.…

Stage 1 Biology Practical Report Isabelle Bury C2 Surface Area : Volume ratio Introduction: A cell is described as the basic unit of all living things and is commonly known as a building block for these living organisms. Cells are considered the fundamental unit of life as it relates to the metabolic processes occurring which allow organisms to stay alive. Cells are responsible for providing structure within organisms, absorbing nutrients from food sources and converting nutrients into energy.…
