Question 1 : The distribution of organisms in a community is affected by the biotic factors and abiotic factors. Abiotic factors are the non-living components in the ecosystem such as air‚ water‚ soil‚ temperature and light intensity. Biotic factors are the living components in the ecosystem such as animals and plants. In an ecosystem‚ the living organisms live together in their non-living environment and function as a unit. This dynamic system starts with species‚ populations‚ ecosystems‚ communities

Ever since then‚ we (and they) have changed a bit to adapt to the different environments we invaded and created” (Gitig 2009). Organisms need to adapt both physiologically and anatomically in order to survive in changing environments. For example‚ Tibetans have developed genes to help them adapt to life at high elevation. While most humans would become very

(Taxa or Taxon) 1b. Why do common names of organisms – like daisy or mountain lion – often cause problems for scientists? The common names of organism often cause problems for scientist because common names can change meaning among languages and from place to place. 1c. The scientific

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
