Q-1 A surgeon wish to predict the live or death (status) of a CABG patient through their pulse rate‚ systolic blood pressure‚ sugar level‚ hemoglobin etc. He got the data from last 1600 surgeries held in a local hospital and applied an analysis. He got the following result Identification: It is binary logistic regression (LOIGT) Coding 0 = Death 1 = Alive The two post-operative status of the patients are death and alive coded by 0 and 1 respectively to use in binary logistic regression.

Digestive processes in both plants and animals convert starch to glucose‚ a source of energy. Starch is one of the major nutrients in the human died. Its presence in foods and other substances can be detected by the blue-black color produced when iodine solution is added to a sample of the material to be tested [5]. Starch + I2 blue-black color Amylase enzyme Proteins which catalyze the chemical reactions are called enzymes. Non-biological catalysts work at wide ranges of temperature and pH‚

Abstract A buffer is a solution that resists changes in pH when H+‚ OH-‚ or H20 is added. By using standard lab equipment‚ a lab pro diagnostic tool‚ and acidic and basic solutions‚ the pH can be found. By recording the pH while adding a base or an acid gradually to a buffer solution you can find the capacity of each buffer to resist drastic changes in pH. The best buffers will keep a solution from becoming either too acidic or basic with the addition of a strong base or acid. Introduction The

The experiment was comprised of two parts. For the first part (effect of temperature)‚ 2 ml of the enzyme solution was placed in a large test tube and labelled as 4℃. In a separate large test tube‚ 2 ml of the buffered starch solution was added. Both test tubes were incubated for 10 minutes in an ice bath with a temperature
