Stem Cell Research Stem cell research is no longer a future unrealistic concept‚ it is here and having enormous impacts on the medical field. Stem cells are the primary cells that can be trained to develop into any human cell tissue such as muscle‚ skin‚ and brain. However‚ in embryonic stem cell research‚ to retrieve stem cells from embryos requires a process called therapeutic cloning where a person’s DNA is put into an unfertilized human egg (effectively cloning a person)‚ the embryo is then

An Introduction to Autism By National Institute of Mental Health Autism. Not until the middle of the twentieth century was there a name for a disorder that now appears to affect an estimated 3.4 every 1‚000 children ages 3-10‚ a disorder that causes disruption in families and unfulfilled lives for many children. Research from 2009 suggests autism now affects every 1 in 110 children. In 1943 Dr. Leo Kanner of the Johns Hopkins Hospital studied a group of 11 children and introduced the label early

Testing on Animals Animal testing can date back to the Ancient times of the Greeks and the Romans. Animal testing and its ethics have always been questioned and some of us as humans do not want to consider animals being on the same level as us. Just because an animal is not capable of speaking to us does not mean they don’t have feelings or that we’re not on the same level. If an animal’s baby was taken away from the mother she would be sad and hurt as would a human mother. Animals do not deserve

ANIMAL TISSUES 1. Classify the animal tissues. On the basis of the function they perform‚ animal tissues are classified into four different types. They are: i) Epithelial tissue ii) Connective tissue iii) Muscular tissue iv) Nervous tissue 2. What are epithelial tissues? What are the characteristic features of these tissues? The covering or protective tissues in the animal body are called epithelial tissues. They also perform the functions of secretion and absorption

simple cells surrounded by a membrane and a cell wall‚ with a circular strand of DNA containing their genes. They do not contain a nucleus or other internal structures that higher cells may have. These are called prokaryotes. Basically all the life you see today‚ including plants and animals‚ belongs to the third domain‚ Eukaryota. Eukaryotic cells are more complex than prokaryotes; the major difference between the eukaryotic and prokaryotic cells is the nucleus. The nucleus in a eukaryotic cell is
