Civilization is a flow of billions of human beings, but it is only few who take up the task of developing it. It is purely their hard work that secures, augments, ramifies and manifests the lives of the rest. (more…)
In order to understand the activity of enzymes at different temperatures the ability of the enzyme to function can be measured. This is important in many applications such as Polymerase Chain Reaction for forensics as well as genetics research where manipulation of temperature-dependent enzymes allows …
Title of the Experiment: Enterobacteriaceae Identification: The Enterotube II System Learning Objectives: After completing this exercise we were able to inoculate an unknown bacterium that belongs to the Enterobacteriaceae by using technology effectively with a Enterotube II. An Enterotube II is a miniaturized multi-test system …
I am going to investigate osmosis when potato is placed in different concentrations of sucrose. I am aiming to witness osmosis in 5 different concentrations of sucrose. I will use 5 varying concentrations so that I have a wider spread to compare the results, and …
PhysioEX notes Autorhythmicity- heart’s ability to trigger its own contractions Phase O- a lot like depolarization in neuronal action potentials. Sodium channels open, increase of sodium INTO cell. Phase 1- sodium channels close, potassium channels close, decrease in potassium and sodium. Calcium channels open, increase …
The symbiotic relationships that establish involving the roots of major plant species and fungi are called Mycorrhizae. These symbiotic relationships differentiated by the two-way movement of nutrients whereby carbon runs to the fungus. The fungus then facilitates the movement of the inorganic nutrients towards the …
Enterococcus By Richard Guilford Enterococcus Enterococcus, or more appropriately enterococci, are a family of bacteria in the division firmicutes (meaning strong skin and referring to the cell wall) and the class bacilli (which refers to its rod like shape). They look just like streptococcus bacteria …
Chemical and Environmental Effects on the Heart Introduction The heart is the centerpiece of the circulatory system, its muscular contractions allow for the timely delivery of essential gases and nutrients to virtually all cells of the body. The pressure created by the heart also plays …
An Analogy of a plan cell to a country nucleus/governement/primie minister/parliament house- they are the control centre of the city or cell. They both control what goes on in the city or cell. the nucleus contains all the DNA or important information, of the whole …
Your Inner Fish: A Review of Chapter 4 In Your Inner Fish, a book about the study of evolution in mammals, chapter four is dedicated to the study of teeth. Neil Shubin is explicit in his insistence that teeth are extremely important when studying evolution …
In Austin many people suffer from seasonal allergies which are triggered by mold spores and pollen grains mainly during spring and fall. Mold spores are responsible for causing seasonal allergic rhinitis also known as hay fever. Molds did not have a specific bloomy seasons but …
Asian tiger mosquito Aedes albopictus, the Asian tiger mosquito or the Forest day mosquito is a small black and white mosquito, about 1/4-inch long. Its white and black color pattern gives it the name “Tiger Mosquito”. A white stripe runs down the center of its …
So far, nearly 100 million animals have been used for experiments annually. Many people have been arguing whether animal testing be banned? Obviously, the answer is animal testing should not be banned. Due to animal can be tested to ensure the safety of some cosmetics, …
In order to build muscle for example, one must gain an efficient mind muscle connection – therefore more experienced bodybuilders have adapted a stronger neurological connection between their mind and the muscle group they have chosen to work out. Thus, by doing a chest/tri split …
Abyssal Zone Steven Jevan 10. 2 Located deeper than 2000 meters underneath the ocean surface, lies a biome that we have barely seen and realize. This unbelievable and incredible biome is called the abyssal zone. With a depth reaching down to 6000 meters, it is …
This module will examine how information is encoded in DNA, and how that information is interpreted to bring about changes in cells and tissues. Objectives : Understand the triplet nature of the genetic code, and know the meaning of the term codon Know that the …
B. Assuming that Joseph’s heart stopped, all of the cellular processes and membrane functions are going to be affected. The loss of oxygen is going to affect everything, ultimately killing off all of the cells. Loss of oxygen and glucose will affect the mitochondria, making …
Nature and nurture are a convenient jingle of words, for it separates under two distinct heads the innumerable elements of which personality is composed. Nature is all that a man brings with himself into the world; nurture is every influence that affects him after his …
Biology is defined as the study of life while psychology examines the human mind and its processes, especially those affecting behavior. Biological perspective links biology and psychology by focusing on the analysis of human behavior based on biological and physical evidence.
Why is biology important? As a field of science, biology helps us understand the living world and the ways its many species (including humans) function, evolve, and interact. Advances in medicine, agriculture, biotechnology, and many other areas of biology have brought improvements in the quality of life.
Chemical biology deals with how chemistry can be applied to solve biological problems while biochemistry is the study of the chemistry of biology. In general, the chemical biology major focuses on small molecules while the biochemistry major focuses on proteins and nucleic acids.
