Rat Dissection Prelab 1. Is your left like your right side? It should be similar to your right but there can be differences like if damage was done to one side or if one side was mutated and disfigured. 2.

Many female snakes (15 of 20 snakes)‚ but few male

The religion I chose to observe was Jehovah’s Witness‚ they usually hold services two times a week‚ and most of the programs involve audience participation similar to a classroom discussion. Worship beginnings with a song from their “Song Book” which leads to prayer and before ending the service with prayer they sing again. All services focus on reading and discussing the Bible and seeing how to apply it in one’s life. Those in attendance—no matter what ethnic group or age—are encouraged to read

and Mussels we dissected. I chose these because‚ for me‚ these dissections were the most fun! Seeing what was inside of the starfish was nothing I had thought it would be‚ and the mussel is something I eat but usually it is mostly cleaned out by then so it was interesting to see what it looked like before it was cooked. As well as dissecting these animals‚ I was able to learn about how they interact with one another. In this essay I am going to cite information from J Exp Biol 2013‚ an article

Aortic Dissection An aortic dissection is a tear in your aorta. The aorta is the main blood vessel that carries blood out of your heart to supply the rest of your body. It comes out of your heart and curves around‚ then goes down through your chest (thoracic aorta) and into your belly (abdominal aorta). The wall of the aorta has inner and outer layers. Aortic dissection occurs most often in the thoracic aorta. This is more likely to happen if the inner layer of the aorta has a weak spot or gets

love the peace of mind knowing there weren’t rats lurking in your walls? Rats create many problems in the world and I believe we should eliminate all rats. One reason rats need to be eliminated is they spread diseases. According to CDC (Centers for Disease Control) rats spread hemmoragic fever‚ Lassa fever‚ Leptospinosis‚ and many more. Having rats running around infected with possibly fatal diseases is far too dangerous. To emphasize the deadly effect rats have‚ we can look at the Black Plague‚ in

FETAL PIG ESSAY Through the dissection of the fetal pig‚ we were able to compare and contrast the structure and functions of the organs to those of a human. We dissected the pig and observed all the exterior and interior structures. The fetal pig’s structure was almost identical to the human body. Since humans and pigs are both mammals‚ it can be very useful to study the fetal pig. We dissected the pig so that we should see the skeletal and organ structures that we learned about in class. Because
