IntroductionFrom an exposure to antigens, antigenic molecules have several epitopes which result in synthesis of a mixture of antibodies. Each B-cell synthesizes a specific antibody. But antigens which contain multiple epitopes stimulate a series of B-cells which ultimately result in multiple cloning of plasma cells that are responsible for synthesizing different specific antibodies. This is termed as polyclonal activity (Kulkarni, 2002). In 1975, Kohler and…
Heart the blood and carbon dioxide then
Heart RateThe circulatory system is made up of blood vessels, such as arteries and arterioles; these vessels takes oxygenated blood from the heart to the thin-walled capillaries which is where exchange of oxygen and nutrients takes place and vessels known as venues and veins return the now deoxygenated blood back to the heart, this is an ongoing cycle. Nutrient molecules then leave the capillaries to…
A the diversity of a microbiome as
A limitation of this is that PCR amplification of genomic DNA is inherently biased by primer design 24,25 and generally only identifies the target organisms. Complex environments are inhabited by organisms from all domains of life. Eukaryotes, including fungi, protozoa, oomycetes and nematodes, are ubiquitous in soils and can be important plant pathogens or symbionts, whereas others are bacterial grazers. The archaea carry out important…
Evolution is the adjustment in
Gigantopithecus Evolution Introduction: In Biology, Evolution is the adjustment in the attributes of species over several generations and depends on the procedure of natural selection. The theory of Evolution depends on the possibility that all species are connected and gradually change over time, (www.yourgenome. org 17 Feb 2017). The theory of evolution is as of now the most prevalent and controversial concept of how life…
The partying, and having fun was all
The roaring twenties, a time for advancements and new technology. After World War 1, there had been and economic boom in the nation where most people just wanted to live their lives. Big cities such as New York and Chicago were viewed as ‘sinful’ because of the way people were living after the war. Drinking, partying, and having fun was all part of this phenomenon.…
Natural to survive and reproduce more than
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term “natural selection”, contrasting it with artificial selection, which is intentional, whereas natural selection is not.Variation exists within all populations of organisms. This occurs partly because random…

Artificial Take an example of mobile phone
Artificial Intelligence (AI) that is a combination of two words Artficial and Intelligence. Artificial means man made and Intelligence refers to the ability to understand think and learn. Artificial Intelligence was first propsed by John Mc Carthy in 1956 in his first academic conference. The idea of machines operating like humans started out to be the center of scientist’s thinking and wheather or not if…
Biology to observe how the inserted potato slice
Biology IB November 26th, 2017 Frau Moll Effects of Osmosis on Living Tissue Research Question: What is the effect of osmosis on a slice of potato in varying salt solutions? Six different concentrations of salt water (0%, 0,4%, 0,8%, 1,2%, 1,6% and 2,0%) will be used in order to observe how the inserted potato slice changes. The length of the potato slice will be measured…
