Cardiovascular System: The Heart Purpose Explain why you did this exercise. Where there any safety precautions you needed to follow? If so‚ what were they? The safety precautions in this exercise were to wear goggles and gloves due to being exposed to chemicals and dissection of the sheep and cat heart. Appropriate work space was also required.

Such experiments were the main contributors to our current knowledge in some fields of science‚ especially medicine. Dissections performed on rabbits‚ mice‚ chimpanzees‚ and other animals‚ along with some imagination may have helped shape what we knew about the human anatomy back in a day‚ but only up to a certain extent. In the end‚ in order to learn more about the human body‚ dissection accompanied by experimentation had to be done on humans themselves.

M1 – Differentiate between those questions that science is currently addressing‚ those that science cannot yet answer and those that science will never be able to answer. There’s many questions that scientist are currently addressing and many they will never be able to answer because of individual opinions and no evidence between any of the answers clearly because you can’t experiment any of it. For example in our modern day society there’s always debates on whether there’s a God or not? Around

Chicken Wing Dissection The chicken wing dissection was very helpful in understanding not only the muscular system but also the skeletal system. We looked at both the bone and the muscles of the chicken wing. We noticed many different things that we had been studying in class. In this dissection we studied structure and function of a chicken wing‚ which is comparable to that of the human arm. First‚ we removed the skin of the wing with the tools provided for us. We examined yellowish tissue clumped

Dissection is the process of studying and disassembling a deceased animal or plant to enrich the understanding of the anatomical structure. As a student I do enjoy dissecting animals because it does give me a good understanding of what our organs and body parts look like and how they are all related. In contrast to that I do not believe it is ethical to do dissections on dead animals and plants. Obviously when you think about what you are doing you soon realize that cutting an animal open is an

Variance in the components of maternal behaviour are categorised into subsections‚ including protective behaviour‚ post-parturient and pre-parturient behaviour and behavioural endocrinology.

Cloning‚ this word only spoke up in science fiction movies‚ many now also be the subject of a documentary. This same one word that for some evokes the dream of a life time a huge leap is scientific world‚ or a lab miracle is synonym of immoral and unorthodox beginnings for other. It has in fact triggered debates among researchers‚ ethicists‚ and politicians all over the world. The ethical controversy over any future experiments that involve the cloning of human beings -- which has NOT occurred
