Biology Laboratory Report MEASURING RATE OF WATER UPTAKE BY A PLANT SHOOT USING A POTOMETER Introduction All plants need salts minerals‚ water‚ CO2 and O2. To fulfill their requirements different plants use different ways. Lower plants use diffusion‚ however higher plants use vascular tissue that is located in the middle of the root and in the vascular bundles in the stem. The transpiration is the important process in the plant. The main reason is that transportation

to move in space. This is because there is no external forces act on the system. The forces acting between the bodies during the small interval of time when they are in contact cause changes in the velocities of each separate body. An exact determination of these forces is not practical but the presence of the forces can be allowed for by using a property known as the coefficient of restitution. The coefficient of restitution is the ratio of speeds of a falling object‚ from when it hits a given

Then a pinch of salt and 1 mL of water was added into each mortar and used the pestle to ground the tissue into a pulp like substance. After it transformed into pulp‚ 50 μl of the fluid extract was taken to be used for the experiments. Doing so‚ this evaluated the actions

experiment is the amount of water absorbed. There are many constants including the same brand of cucumber slices‚ the same amount of each substance applied‚ the same measuring tools being used‚ and the same observation time. The control of these scientists’ experiment is no substances applied. The Scientists have hypothesized that if salt‚ sugar‚ baking powder‚ are applied to the cucumbers‚ the salt will absorb the most wa‚ then the salt will be more efficient in absorbing water from the cucumber

Ammonia and Its Salts 1. Ammonia‚ NH3 is a very important compound in industry. 2. The main uses of ammonia: a) To manufacture nitrogenous fertilizers such as ammonium sulphate‚ ammonium nitrate and urea b) The liquid form is used as a cooling agent (refrigerant) in refrigerators c) As a raw material for the manufacture of nitric acid in the Ostwald process d) To be converted into nitric acid used for making explosives e) As an alkali to prevent the coagulation of latex

officially ban. Modern audiences have become accustomed to attitudes‚ language‚ and stories that are political‚ graphic‚ violent‚ and more than just a little bit avant garde. Obviously‚ such was not the case in the blacklisting days of the 1950s! “Salt of the Earth” violated every aspect of the white‚ middle-America‚ conservative mindset of 1954. As a political statement‚ it demonstrated the inter-connection that exists between working class‚ feminist‚ environmental and Latino concerns‚ and yet it

The percent discrepancy obtained for one spring was 14.66% and the percent discrepancy for two springs was 0.375%. Objective: The physics concept being studied from this experiment is the spring constant and simple harmonic motion. Equipment Part 1 Two nearly identical springs Long rubber band Support stand with

Behavior of Gases and Absolute Zero Determination Lab Report Experiment 4 Introduction In this experiment we measured the relationship between temperature‚ volume‚ and pressure. Objectives: Conduct a set of experiments‚ each of which illustrates a gas law. Gather data to identify the gas law described by each activity. Complete the calculations necessary to evaluate the gas law in each activity. From your results‚ derive a single mathematical relationship that relates pressure‚ volume‚ and
