Type 2 diabetes is the most common form of diabetes. In type 2 diabetes‚ either the pancreas does not make enough insulin (insulin is a hormone that helps glucose to enter cells) or muscle cells are unable to use insulin properly. As the result‚ a diabetic patient has very high blood sugar levels. When the sugar or glucose level is over 600 mg/dl‚ it’s dangerous to the diabetic’s health. Untreated diabetes affects the eyes‚ nerves‚ kidney‚ heart and blood vessels. Type 2 Diabetes is usually controlled

According to Fremgen (2012)‚ every state has a statue or regulation that necessitates that all health care professionals and physicians report all cases of acquired immunodeficiency syndrome (AIDS) to the department of health local or state level. This would allow Dr. K to meet his obligation in reporting the communicable disease. In some states it is also legal to inform a spouse‚ needle sharing partner‚ or other party that may be at risk of contracting the disease (Fremgen‚ 2012). In this case

Membrane Functions: Aim: To demonstrate the process of osmosis using a chicken’s egg Hypothesis: I predict that the egg’s mass after 10 min. in the 5% salt solution would increase due to and balancing out the solution. In the 10% salt solution‚ the egg’s mass would decrease since there is a high amount of salt. In the dilute water solution‚ the egg’s mass will increase‚ as the membrane would take in that water. Materials: 1- One fresh egg 2- One plastic spoon 3- One plastic fork

Describe the structure and function of each of the eukaryotic organelles. ”A eukaryotic cell is sectioned by internal membranes into different functioning categories called organelles. For example‚ the nucleus houses DNA‚ the genetic component that controls the cells activities. (Boundless. “Introduction” Boundless Biology). The Cytoplasm is the material between the cell membrane and the nucleus. It has a lot of responsibilities within the cell. It contains enzymes for breaking down waste and also
