TEMPERATURE ON CATALASE ACTIVITY AIM The aim of this experiment is to find out the effect of temperature on catalase or hydrogen peroxide. This will enable us to tell at what temperature hydrogen peroxide is most efficient. This (degradation) reaction will help us determine some of the catalase’s different attributes. HYPOTHESIS In this experiment it would be safe to hypothesise that no activity would take place at 1 to 20 degrees. It would be probable that a little activity would take place around

Introduction Contractions of the uterus can occur throughout pregnancy. Contractions are not always a sign that you are in labor. Contractions that occur before labor are called Braxton Hicks contractions‚ or false labor. These contractions are sometimes confused with true labor. What are Braxton Hicks contractions? Braxton Hicks contractions are contractions of the uterus that occur before labor. Toward the end of pregnancy (32–34 weeks)‚ Braxton Hicks contractions can develop more often and may
