According to the results‚ the experimental group had a huge impact when the diluted concentration of caffeine was put in compared to the control group that contained no concentration of caffeine. The hypothesis was supported because a significant decrease of the total number of cells when caffeine solution was added to the experimental group was clearly shown. An addition of small amounts of caffeine does inhibit cell proliferation and affect cell viability during the lab experimentation one more

1.CANCER Cancer /ˈkænsər/‚ known medically as a malignant neoplasm‚ is a broad group of diseases involving unregulated cell growth. In cancer‚ cellsdivide and grow uncontrollably‚ forming malignant tumors‚ and invading nearby parts of the body. The cancer may also spread to more distant parts of the body through the lymphatic system or bloodstream. Not all tumors are cancerous; benign tumors do not invade neighboring tissues and do not spread throughout

This standard has been approved for use by agencies of the Department of Defense. 1. Scope 1.1 The primary objective of metallographic examinations is to reveal the constituents and structure of metals and their alloys by means of the light microscope. In special cases‚ the objective of the examination may require the development of less detail than in other cases but‚ under nearly all conditions‚ the proper selection and preparation of the specimen is of major importance. Because of the

egg. The word cell comes from the Latin cellula‚ meaning a small room. The descriptive name for the smallest living biological structure was chosen by Robert Hooke in a book he published in 1665 when he compared the cork cells he saw through his microscope to the small rooms monks lived in. Each cell is at least somewhat self-contained and
