GERMS For as long as humans have been on this planet‚ the microscopic life forms that we call germs‚ or pathogens‚ have been here too. For all this time they have been multiplying in the soil‚ in the water‚ and in our bodies. They are in the mouth‚ on the skin‚ and even in important organs. But that is not always a bad thing‚ because humans could not live without germs. Some germs‚ or "microbes" help digest food‚ while others produce vitamins. Most of the time‚ people and germs coexist peacefully;

Some bacteria are good for our bodies; they help keep belongings in balance. Good bacteria live in our intestines and help us use the nutrients in the food we eat and make waste from

1. Explain what clonal selection theory is and its role in humoral or antibody-mediated immunity. Clonal selection theory is a rationalization for the growth of lymphocyte specificity and diversity during immune development. This theory demonstrates how immunological memory can deliver a fast reaction when coming into contact with an antigen that has been seen for the second time. Specifically‚ the clonal selection theory is based on the concept that premature‚ undifferentiated lymphocytes in the

Upon closer examination of the Vishnu sculpture shown above‚ one can begin to understand how the artistic aspects of expression/anatomical configuration‚ symbol‚ material‚ and scale both reflect and illuminate specific facets of the historical context in which it was created.

Anatomical Terms Certain terms are used to describe the location of body parts‚ regions of the body‚ and imaginary planes by which the body can be sectioned. You should become familiar with these terms before your study of anatomy and physiology begins. Anatomical terms are useful only if everyone has in mind the same position of the body and is using the same reference points. Therefore‚ we will assume that the body is in the anatomical position: standing erect‚ with face forward‚ arms at the sides

Clare Worley 6S 4 - 16 - 18 What Surface in OLV has the most Germs? Introduction I have tested several surfaces in Our Lady of Victory to see which surface has the most germs. I tested ten surfaces and let the petri dishes grow for five days. Over the five days I counted the spores each day and took pictures every other day. It is amazing how things can look and feel clean but they are actually filthy. It is also crazy how many surfaces we touch every day and how one
