I don’t believe in having cell phones during class‚ just like a lot of others. Cell phones are distracting students who are around them‚ students are not paying attention‚ their entering phone numbers‚ playing games‚ and they are getting in trouble. Does this sound appropriate to you? Do you agree with having cell phones in class? If you say yes to these questions‚ I hope to persuade you by the end of ‘Cell Phones in Class’. I have noticed many students have been texting during class. I don’t know

To do so‚ it is essential to

Biology Period 1 Stem Cell Debate I think that we should stick to researching adult stem cells because it is more ethical‚ better success rate than embryonic cells‚ and they are more knowledgeable to the people. Adult stem cells are controversial but way less than embryonic stem cells. Stem cells are found in all multicellular organisms and are divided through mitosis. Adult stem cells are found in various tissues. Adult stem cells can be regenerated into specialized cells just not as many. Embryonic

Cell Size Control David A Guertin‚ Whitehead Institute for Biomedical Research‚ Cambridge‚ Massachusetts‚ USA David M Sabatini‚ Whitehead Institute for Biomedical Research‚ Cambridge‚ Massachusetts‚ USA Growth in biological systems is defined as the accumulation of mass‚ which leads to an increase in size. In this article‚ we discuss how cells‚ organs‚ and organisms normally control growth‚ and how deregulated growth can lead to a variety of pathological conditions. Introductory article Article

Cells Now we need to discuss CELLS. You’ve probably heard of cells‚ and may even know of a few‚ such as blood cells‚ nerve cells‚ or skin cells. What are these things called cells? Cells are the smallest living things. You’ll be learning a lot about cells in this course. For now‚ however‚ I’ll introduce you to just a few basic things about them. Cells are extremely tiny organisms that carry out all of the functions of life inside a thin layer of “skin” called (unimaginatively) the CELL MEMBRANE

Red blood cells transport oxygen from the lungs to various other organs and tissues with the help of a protein called hemoglobin. The main cause of sickle cell disease is when hemoglobin mutates into an abnormal type called

Suddenly‚ stem cells are everywhere. Once relegated to the depths of esoteric health journals‚ the microscopic clusters have made their way to the nation�s front pages. The complexity and drama surrounding these relatively simple cells has increased due a ticking clock: By the end of the month‚ President Bush is scheduled to decide whether to continue federal funding for stem cell research. The question of using stem cells for research is intrinsically scientific‚ and yet has become the political

Stem cells. To be or not to be It is one of the most evocative phrases in the lexicon of science: stem cells research‚ the creation of cells that can be used to make people healthier‚ stronger and even can treat cancer – the greatest killer of our time. Stem cells have been touted as one of the most significant discoveries in medical history! The ongoing research in this field hold high hopes that in a few years stem cells used in genetic therapy may be able to cure or alleviate the suffering
