my first glimpse at molecular biology then. But that brief introduction to molecular biology was enough to compel me to the idea that I want to spend my whole life working and conducting research on it. That passion and zeal brought me to where right now I am. I have successfully completed my masters from the Department of Genetic Engineering and Biotechnology‚ University of Dhaka. I want to note that very few universities offer courses related to molecular biology here in Bangladesh but University

Biology and Behavior Animal testing is not a problem in today’s society because it is beneficial to humans. It seems unethical to put animals through such pain and torture‚ but if we stopped it completely there would be a large amount of human lives lost. How could this be? The further advancements in medical and technological science is inevitable. Therefore‚ if the testing must be done to learn more about the brain and body‚ which species (animals or man) seems expendable for such testing. The

REVISION NOTES FOR PRELIM BIOLOGY: [ A LOCAL ECOSYSTEM ] ~ Ecosystems: “any area that contains living organisms interacting with each other and their environment. In a balanced ecosystem‚ there is a flow of energy through it and recycling of some materials” Inputs and Outputs of Ecosystems include: - the energy flow through the ecosystem; energy from the sun flows one way through‚ with heat loss at each trophic level - the input and recycling of inorganic and organic material (matter) - the

In this lab we will look at how molecules move across the membrane of a cell . Osmosis is the movement of water across a cell membrane.In osmosis the cell membrane is selectively permeable‚which allows for the membrane to control what types of substances that passes through.Transportation can either be passive or active.Passive transport does not require the use of added energy where as active transport requires the cell to use energy. Diffusion is the simplest form of passive transport. Using

Marine biology I would be an extremely happy man if I could do what I love for the rest of my life.With the many issues going on in our waters such as overfishing‚ pollution‚ and global warming. Marine biologists work hard day in and out to put an end to these terrible things that occur more often that one thinks. Did u know Water covers the 71 percent of the earth. As a kid must of my summers were spent at my family’s lake house and I loved every minute of it. I saw a lot of terrible things
