did. Even though sociology comes with lot of work once the subject begins being taught to you‚ you start to unexpectedly experience many of the things discussed in the topic‚ which makes it easier to remember. For example you get taught about the effect of self-fulfilling prophecies the process in which a student gets told that they are not doing well by peers or others and so they stop trying‚ I experienced this in many class rooms around school. One time in a history lesson my friend had a confrontation

Biology- Maintaining a Balance Summary 1. Most organisms are active in a limited temperature range 1. identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates Enzymes are proteins which act as catalysts in living things (they lower the amount of energy needed for a reaction‚ therefore increasing rate of reaction). Enzymes speed up reactions but are not used up by them. Enzymes catalyze only one

The effect of Lead ions on amylase activity Aim What is the effect of Lead ions on the enzyme Amylase. And does it have an inhibitory effect‚ which causes the substrate‚ in this case starch to be blocked from the reaction process in the enzyme catalyst. Also is the effect reversible or irreversible‚ which is put on the amylase. Method Apparatus and substances required Test tube holder 2% starch solution 6 boiling tubes labelled 1 to 6 1% lead nitrate solution 6 test tubes labelled A to E‚

encode for positive mediators of cell proliferation and growth. They drive the proliferation of the cell ex: growth factor receptor Tumor suppressor gene encode negative growth regulatory factors. They counter the effects of protooncogenes. In cancer cells they bypass the negative effects of these so they continue to grow Cancer epidemiology is the study of distribution of various cancer types among world populations with consideration of specific risk factors and etiologic agents involved in disease

Experiment 10 – Enzymes Enzymes are proteins that act as catalysts for biological reactions. Enzymes‚ like all catalysts‚ speed up reactions without being used up themselves. They do this by lowering the activation energy of a reaction. All biochemical reactions are catalyzed by enzymes. Since enzymes are proteins‚ they can be denatured in a variety of ways‚ so they are most active under mild conditions. Most enzymes have optimum activity at a neutral pH and at body temperature. Enzymes are
