A Cell Bio Problem Set 1

Chemistry relates to everything we touch, see, smell, hear, and taste because atoms make up everything in the universe. Chemistry influences so much in our everyday lives that it is hard to think of an activity that does not involve a chemical process in some way. The science also plays a major role in the human body. Our bodies are made up of chemicals, in fact almost 96% of our body mass is made up of four different elements: hydrogen, oxygen, carbon, and nitrogen. Besides the physical way I am affected by elements, chemistry also majorly affects me in my line of work as a certified nursing assistant. As a certified nursing assistant I work in a nursing home and

Physics is involved in all of our daily activities. Most of the time, however, physics is overlooked and never acknowledged. It is important to understand different aspects of physics because physics tells us how and why certain events occur. By definition, physics is the search for laws that describe the most fundamental aspects of nature: matter, energy, force, motion, heat, light, and other phenomena. There are many different sectors of physics, but we will be focusing primarily on mechanical physics. Each step of the field goal kicking process involves physics, which we will explain.

That the breadth of life is fundamentally defined by its molecular makeup fascinates me; from the significance of the RNA World Hypothesis to the implications of epigenetics, the reach of biochemistry is something I hope to explore further at undergraduate level.

The biological school of thought relied on strict biological characteristics, which we saw in the theories of Lombroso, Goring, Hooton, Sheldon and others (Akers & Sellers, 2013). As America moved into the 20th century, the application of biologically oriented theories eventually began to shrink (Lilly, Cullen & Ball, 2011, p.36). However, today we see a more modern biological school of thought. This more modern approach contains biological explanations that are based on new scientific discoveries and technical

Rudolf Virchow was a german physician that help create the theory of cells inside our bones. He was born in Swidwin Poland and grew up being an only son to a modest merchant. His works help german doctors find cures for temporary illnesses, but it wasn’t just the german doctors, it was everyone around the world. Things changed fast when it was 1900s for him, in 1903 he jumped off a electric cart and broke his thigh bone and femur, and changed Rudolf and the people around him. Rudolf Virchow never believed in Evolution.

The laws of physics are what the world lives by. They tell the world that every action has an opposite and equal reaction, that if something can go wrong it will, and that things, like people, can be thought of as both dead and alive at the same time under the correct circumstances. Even though the world lives by the laws of physics, even if not everyone knows it, René Descartes proposed a concept called interactive dualism which appears to violate a law of physics known as causal chains, when interactive dualism actually plays a part in the causal chains.

Eukaryotic cells use around 5% of their genes in order to synthesise lipids. There are many different types of lipids present in membranes. Firstly, phospholipids are the most abundant type of lipid in all biological membranes and are composed of a hydrophilic phosphate head and a hydrophobic fatty acid tail. Some membranes also contain glycolipids, which are sugar containing lipids. In eukaryotic membranes, but not prokaryotic membranes, cholesterol can be found, which is a lipid and steroid. Whilst lipids do play a structural role in membranes and function in compartmentalisation, lipids also have many functions in the cell. In this essay I will discuss how lipids play a role in the ability of receptors to function, budding and fusion, fission,

As Arthur Peacocke points out, while a dissipative system’s thermodynamic fluctuations at the micro-level are probabilistic and unpredictable, they are still not isolable from the whole corpus of physico-chemical theories that govern the macro-level of the environment. In other words, random mutations in the DNA can affect the ability of an organism to procreate itself. Yet ultimately, in the environment, the persistence of novel organisms is subject to the law of natural selection that constrains their survivability in extended

Understanding the complex processes that occur within our bodies, that sustains life, is what attracts me to study biochemistry. The subject explains the complexity of life to a molecular level and holds the answers to the most fascinating and compelling questions about the origin of life. Its intriguing that it uses chemical principles to interpret the biological processes that occur in living organisms. The fact that the reliance on medical research is increasing, demonstrates the importance of studying this this subject. I feel i can have a significant role in the advances of drugs and the healthcare system by gaining broader knowledge on this inspiring field of study.

Ever since I can remember, I have been obsessed with mechanical systems. Every birthday and Christmas I asked for a remote control car or plane, only to end up taking them apart the same day. I was passionately curious about how and why the world worked. My mother, a professor of Biology, recalls my insatiable curiosity and that I was always asking “why?” As I grew older that interest shifted more towards the mystery of life; how was it possible that everything we know is the result of a chance organization of molecules to form complex cell networks? It was about this time that I was filling out college applications and I decided to major in Bioengineering and minor in physics. I felt that this would enable me to understand the biological

The volume of the cell affects the rate that the chemicals are made and used within the cell.

Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment, why they hold the different properties that depict them, how their atomic structure may be fathomed, and how they may be manipulated and changed.

The Quantum Mechanics are weird, yet incredibly powerful theory of the subatomic world, in which everyday concepts to do with the forces and motion are seen in a different perspective, as they do not longer apply in the same way. This calls for a new type of mechanics based on what scientists call "quantum" rules.

Although it is clear that the discovery of the structure of DNA was not a Kuhnian Revolution, the information is still a crucial part of the foundation of biology and human understanding of their surroundings. Naturally, humans exist in a dimension where they acknowledge their surroundings with the help of the naked eye. With physics, humans are able to venture to a macroscopic dimension of enormous celestial bodies enveloped in vast, seemingly endless space to interpret the behaviour of their surroundings in addition to what was currently known. The discovery of the structure of DNA enabled humans to venture into a new dimension to further extend their understanding of the world to microscopic elements. Not only does the new dimension allow for the development of scientific explanations for the behaviour of organisms, but it also grants humans the knowledge and power to manipulate their surroundings at a new microscopic dimension, thus allowing them to advance civilization in a completely new frontier.

In other words, it must reflect the way an aspect of the natural universe works. For example, the fact that falling objects fall towards the ground at 9.8 m/s^2 is a law of nature. The scientific law that would reflect this is the statement “free falling objects fall at 9.8 m/s^2.” In other words, the statement “falling objects fall towards the ground at 9.8 m/s^2” is true if and only if falling objects actually fall towards the ground at 9.8 m/s^2. Another important distinction to make is that a law of nature cannot be centered on one object. For example, the fact that I exist is not a law of nature. This follows from the fact that all candidates for scientific laws must be objective features of the
