ABSTRACT The experiment was conducted to determine the carcass characteristics and haematological indices of broilers fed diet supplemented with phytase additive at finisher phase. 180 birds were procured at day old and were brooded and raised for four weeks prior to commencement of the data collection. The completely randomized design (CRD) was used as the experimental design. There were 5 treatments (T1, T2, T3, T4 and T5) each replicating 3 with birds, treatment one was used as the control while
1. Describe risk assessment in genetic counseling Genetic risk should be estimated as precisely as possible as it is an important component of genetic testing and counseling, and for family decision making. It is always good to take out extra information from pedigree charts and genetic testing as it can improve the accuracy of risk assessment drastically. The risk can be calculated using Bayesian analyses. Among populations, families or individuals within the same family have significantly different
painting “Enguerrand Quarton, Cornation of the Virgin”. Another type of balance is asymmetrical balance. Balance can be achieved even when both sides of the composition lack symmetry but they appear to have the same visual weight. So Asymmetrical means neither side reflects or mirrors the other. An example is of Johannes Vermeer’s “Woman Holding a balance”; the subject is the balance between material and spiritual worlds. In this painting light and
Volume Lab In this four parted lab the purpose is to use measurement and water displacement and calculations to find the volume of various objects. Part A questions were how much drops of water were needed to make 1mL the original hypothesis made was ten drops however this was proven wrong once the data in which twenty drops of water rose 10 mL of water to 11 mL of water, nineteen to rise from 11 mL to 12 ml, and finally eleven drops of water to rise from twelve mL to thirteen mL. Once the average
able to package products properly if engineers know exactly how fast the item flows out of the machinery. Solids, liquids and gases are the commonly known states of matter that consist of distinguishable physical properties. A solid has a fixed volume and shape consisting of rigid particles locked into place. Because a solid’s particles have little free space to slide past one another, solids are not easily compressible and do not flow easily. An example of a solid is a couch. A
The question is, how does a physical or chemical change affect the mass of a substance within a closed system? To respond to this question, my group did a lab to determine whether or not the mass would change or not. Our lab was to have a plastic bag containing baking soda, then add a cup of vinegar and a block of clay to the mix. We made sure to weight every element separately and then add them up for our total mass of 31 grams before the reaction. During the reaction, as soon as the vinegar was
The first measurement that was retrieved as the mass of the metal object was 24.15 g. This was repeated for a second measurement of 23.85 g, and a final measurement of 23.82 g. All three mass measurements were recorded. Moving forward, to find the volume of the metal object, the graduated cylinder
Density: A Characteristic Property I Purpose The purpose of this experiment is the density of six different substances. The way to figure this out is by finding the mass and volume of each of the substances. The hypothesis for the different experiments is that with each of the different substances and mixtures will be different depending on what they are. II Equipment The late nite lab was used to conduct this experiment. The product used were a balance, a graduated cylinder, water, Ethanol, and
3. Results and Discussion 3.1 Excess molar volume The experimental values of densities for pure components and their binary mixtures as a function of mole fraction at T = (303.15 to 313.15) K are given in Table 2. Excess molar volumes V^E were calculated from the measured values of density using the following equation: 〖 V〗^E = V_m-V_1 x_1-V_2 x_2 (1) V^E=((x_1 M_1+x_2 M_2)/ρ_m
mentions the Column volumes of Gel Filtration experiment: Void Volume (Vo), Elution Volume (Ve), Included Volume (Vi), Entire Volume (Vo + Vi), and Inert Volume (Vg). Void Volume (Vo) came out to be 1.25 ml. It was calculated by adding all the fractions that contained blue dextran. Blue Dextran was the biggest substance in size which made it impossible to fit in the available pore sizes of the beads. Void Volume represents the space between the beads in column. In addition, Elution Volume (Ve) came out
Water Olympics Lab Write Up In station one, we explored the idea of density. Density is the amount of cmpactness in an object. We used oil and water, and observed the density of each substance. when pouring the two back and forth, the oil moves slower and the water moves faster and more choppy then the vegetable oil. Seeing this, oil was presumed to be more dense, so I made a hypothesis that if testing the density of oil and water, oil is more dense than its counterpart of water. After a trial
Graphing to Determine the Density of Unknown Metals Purpose: The purpose of this lab was to graph and compare measurements of mass, volume, and density of two unknown metals. Relationships in data and physical appearances were observed and used to identify each metal. The density was shown as the slope of the graph as both were equivalent to mass divided by volume. The experimental density was then compared to the actual value and a percent error was determined. Materials: Equipment and materials
“P1V1 = P2V2” shows that as the volume increases, the pressure of the gas decreases in proportion, as long as the temperature stays the same. The relationship between pressure and volume was first noticed by mathematician and astronomer Richard Towneley and experimenter Henry Power. Robert Boyle, a chemist and physicist, confirmed the discovery and published the results in 1662. According to science historians, Boyle’s assistant, Robert Hooke, built the experimental rig. The law is based on air
liquid wax. Here are some important measurements of part A. Before heating the candle weighed one gram, and the test tube and beaker weigh 40.2 grams. Then after heating, the test tube, beaker, and candle weighed 41.2 grams all together. Which then means that the candle weighed one gram after heating. Therefore, the candle’s mass stayed the same, and part A demonstrated a physical change since the candle could be put back into its original state if someone tried very hard to do so. Part B however,
results tested in the lab. One significant finding of the experiment based on the data about the three cubes was the inverse relationship which was as cell size increases, the surface area to volume ratio decreases. To find the ratios, the calculation of the surface area of each cube (length x width= cm^2) and the volume of each cube (length x width x height= cm^3) was necessary. As a result, the ratio of surface area to
INTRODUCTION Density, mass divided by volume, is one of the most important characteristic of matter (Sciencing) since it affects whether objects will float or sink, thus making it hugely important for the workings of the universe and in daily live (Sciencing). All objects have density and that density can increase or decrease as the result of actions taken on the object (Sciencing), such as adding salt into a substance like water, as has been done in this particular experiment. When salt is dissolved

Purpose- The purpose of the lab is to discover how to measure the mass and volume of liquid and solid samples, such as water, olive oil, vegetable oil, and other solid samples, as well as using the correct number of significant figures and determining how to calculate and find the density and specific gravity of each of the substances. b.) Equipment-
physical property of matter, as each element and compound has a unique density connected with it. Density defined in a qualitative manner as the measure of the relative "heaviness" of objects with a constant volume. For gases the density may amount with the number of gas molecules in a constant volume. Helium balloon: Compare the behavior of helium filled balloon with that of an air filled balloon. Even taking into account the weight of the rubber balloon, the helium balloon floats on the air and is
concentration of water. There are various factors that affect osmosis such as: concentration, surface area and temperature. The concentration of solutions can affect the rate of osmosis, as there is more difference in the concentration of the solutions, which means osmosis, will take place quicker. Surface area could affect osmosis based on the ease by which molecules can get through the semi-permeable
the differences in density between soft drinks. Rather than calculating using two different methods to calculate for the same substance we had two different soft drinks, diet and non-diet Coca-Cola. We then used two volumetric pipets to measure the volumes of the soft drink, then placed the soda in a beaker to calculate the mass using an analytical balance. The questions that I considered before beginning the experiment were, “How does each method of calculating density affect the outcome?’ “How does
