Transport System of Organisms Problems faced by Multicellular Organisms: a)Big size-the total surface area to volume (TSA/V) is decreased . Rate of diffusion of substances into and out of all body cells is low. b)Cells are often located far away from the external surface of the body. How multicellular organism overcome these problem? a)Have specialized structure to increase the surface area for the exchange of respiration gases. b)Have transport system to get gases respiration in and

Genetic engineering From a Christian perspective a biological topic that has many ethical issues is genetic engineering. Genetic engineering is the process by which genetic material is changed in such a way to make possible the production of new substances or new functions. In other words‚ it is the alteration of genetic material by direct intervention in genetic processes with the purpose of producing new substances or improving functions of existing organisms. It is considered a young and exciting

A controversial issue of the twenty-first century is the possible application of new techniques in genetic engineering to produce human clones. Up until now genetic engineering and cloning has been used to clone plants‚ unicellular organisms‚ amphibians and simple mammals. This has led to significant advances in agriculture‚ industry‚ and medicine. Newer techniques in genetic engineering have enabled scientists to clone more complex mammals and opened up the possibility of cloning humans. Although

Do you really know what is in the foods you eat? Most likely not. You probably have never heard of the words genetically modified organisms. It is time to open your eyes to this silent problem that is occurring right now. Genetically modified organisms are in the foods we eat and are ultimately making people sick. Research has shown that consuming genetically modified foods increases your risk for getting cancers and tumors. The only way to avoid it is to eat organic which is not always affordable

Designer Babies The first batch of genetically modified babies were created in 2001. Out of the 30 babies that were born‚ 15 were found to have DNA from three different adults. Although having DNA from more than two sources can occur naturally‚ these 15 babies were created with a method called “cytoplasmic transfer‚” which had been banned by the FDA . The method was initially developed to save female eggs that had been difficult to fertilize and was showing much promise—until tracking the growth

Genetic Engineering Do you think that Genetic engineering is a positive step in our development? Many people think that genetic engineering is the next step in the evolution of humanity and has many benefits. However‚ genetic engineering presents unprecedented ethical and social concerns‚ such as damaging nature‚ limiting human autonomy and risking to human health. First of all‚ genetic engineering can cause widespread crop failure affecting the natural environment. Nowadays‚ many people think
