Since my time at secondary school I have always been very keen on the scientific subjects especially Chemistry and Biology. Topics such Haematology and Stem cell regeneration‚ have given me a greater understanding of the methods involved in diagnosing‚ analysing results from experiments‚ and then treating diseases accordingly. I also have a keen interest in reading scientifically based journals‚ as it gives me an insight into new technologies and methods used to treat diseases‚ and know that regenerative

She told me she learned about him in high school when she needed to do a project on him in her advance biology class. Barbara explained to me that Daly was the first African American woman to get a Ph.D in chemistry. When I asked how she was familiar with Daly‚ she just answered‚ she learned about her sometime in high school. I asked Barbara how she felt that

Hardy-Weinberg Equilibrium One of the most difficult concepts to understand about the process of evolution is how changes in the genetic composition of a population affect the phenotypic composition of a population‚ and how both ultimately act to allow evolution of the species. Charles Darwin’s theory of evolution emphasizes that populations‚ not individuals‚ evolve. The purpose of my experiment was to test the allele and genotype frequencies. Alleles for a gene are represented by letters of

When leading scientific theories and concepts somehow manage to find a way to your dinner table and become the subject of discussion while you much down on beef and boiled broccoli‚ there’s a chance you might have nothing to add to the conversation. And after hearing comments and arguments made by the rest of your company or family members‚ you would have wished you had a proposal to make. There are many breakthroughs that one could call upon‚ but there is one theory that has altered the way the

Zoology Connect Quizzes Chapter1 Your friend releases a pair of goldfish from an aquarium into a pond. The fish survive long enough to produce many young. Returning to the pond after several years‚ you find that only drab olive-brown offspring remain from the original brightly colored golden parents. Select any factors listed below that would have promoted the survival of olive-brown fish over the brightly colored variety. The fish in the wild spent most of their energy finding food and

Who do you think of when a person says “evolution”? Charles Darwin probably came into your mind first‚ didn’t he? Surprisingly‚ Darwin is not the only evolutionary theorist‚ as there are two others with similarly different ideas. Jean-Baptiste Lamarck‚ Alfred Russel Wallace‚ and Charles Darwin all investigated this field of science. Jean-Baptiste Lamarck was the first to have extended theories of evolution. In 1794‚ Lamarck started working in the natural history museum‚ Jardin des Plantes‚ and
