zmosis The IB Lab Report Measuring osmosis 1. Introduction My experiment is about osmosis on a potato and if or the quantity of salt affects osmosis. I would do the experiment with 5 potatoes cut into squares all the potatoes weight the same so the weight can`t be a variable the I put the potatoes on 5 different plastic cups with different amounts of salt and then I weight them again to see if the quantity of salt affected the osmosis of potatoes 1a. Research question ¿Does the quantity

This means that all of the HA will be neutralized‚ causing the pH to change. Because of the rapid pH change around the equivalence point‚ the titrant has to be added in lesser and lesser amounts as we approach the equivalence point.

Introduction In this lab we had to design a system that would test if changing the mass‚ angle of release and length would have any effect on the period of a pendulum. Hypothesis As the length‚ mass and angle of release change‚ the period (T) will change for each one of these factors.

root tip of a plant spend a comparatively long time in the mitotic phase‚ whereas those cells comprising slow-growing tissues would spend most of their lives in interphase. Non-dividing cells remain in interphase and never enter the mitotic phase. (Lab Manual 64) Interphase is the synthesis of biological molecules including DNA and duplicated DNA with associated proteins. These comprise the chromatin that begin to condense toward the end of this phase‚ but are not yet visible. The nucleoplasm

Determining the Catalytic Properties of the Enzyme Peroxidase Extracted from a Turnip Under the Conditions of Temperature‚ pH‚ Boiling and Competitive Inhibitors By Robin Caserta BIO 101 September 30‚ 2013 ABSTRACT The enzyme‚ peroxidase‚ extracted from a turnip was tested for its efficiency in binding to its substrate and its stability under several conditions. To do this‚ we tested effects on peroxidase activity‚ first‚ with different amounts of the enzyme‚ next at temperatures of

Title: Enzyme Catalysis of Hydrogen Peroxide by Catalase Problem and Objectives: How do different temperatures and different levels of pH affect the reaction rate of the enzymes in chicken liver? Demonstrate the activity of an enzyme in living tissue‚ observe the effects of changes in temperature and pH on the activity of an enzyme‚ perform analyses for the presence of an enzyme in tissues‚ and analyzing relationships between environmental conditions and enzyme activity. Background: Cells produce

Biosphere Lab Report A biosphere can be defined a lot of different ways. Our interpretation of a biosphere is the area in which life can be contained within. In the case of the earth‚ it means as high as a bird can fly and as deep as fish can swim in the ocean. A biosphere is a closed system that has a constant flow of energy between the organisms living within it and it needs nothing outside of itself but sunlight to continue to be sustained. At the University of Arizona‚ they attempted to build

Abstract In this experiment‚ the preferences of mealworms towards lighted and dark environments were tested. The main question posed was whether the behavior of the mealworms would be affected by the variable of light‚ and whether they would move towards or away from the light source (taxis). We placed ten mealworms into two adjoining containers and tried to simulate the effects of above ground and underground by exposing the mealworms to minimal amounts of light in one of the containers (underground)
