The following points highlight the three important examples of transgenic animal. The examples are: 1. Cloning Dolly 2. Transgenic Mice 3. Reporter System. Example # 1. Cloning Dolly: In February 1996, Ian Wilmut and co-workers from the Roslin Institute and PPL Therapeutics, both in Edinburgh, Scotland, reported in Nature journal that they had successfully cloned a sheep from a cell [...]
In this article we will discuss about the origin of the frog heart beat with the help of suitable diagram.

Keith and Flack (1907) have described that from the S.A. node the heart beat first [...]
In this article we will discuss about:- 1. Introduction to Cardiac Output 2. Normal Values of Cardiac Output 3. Distribution 4. Control 5. Methods of Measuring 6. Factors Influencing. Introduction to Cardiac Output: At each beat certain amount of blood is pumped out by each ventricle into the circulation. This is called cardiac output. Two terms are used: 1. Stroke [...]
