As said before by many people‚ the better man in certain situations is the person that learns that they are wrong‚ are willing to learn from their mistakes‚ for the sake that they will be able to move on forward from what they learned. The North and the south are like a teacher and student‚ the North can teach the South as a student how lead the reconstruction era for it to become successful however‚ its up to the South as the student to see what they think is best. As so the South did act foolish

Lab Time/Date ___ Activity 1 Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. Size of material and concentration 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? The molecules were too large to pass through. This is what I predicted on my Hypothesis. 3. Describe the results of the attempts to diffuse glucose and albumin

L.O CYP 3.1 1.2 The difference between sequence of development and rate of development. Children will usually follow the same pattern of development‚ the ages of which they reach them could vary depending on them as an individual as each child is unique and will develop at their own rate. Goals of development are given on a wide average of when the children may be expected to reach this particular stage. In schools some children stand out from the rest of the class because they have reached

Unit 01- Child and Young Person Development (1.1) 1. Explain the difference between sequence of development and rate of development and why the difference is important. (1.1) It is important to know the difference between the sequence and the rate of development as it gives us direction when it comes to monitoring child/young person’s needs during stages of their school years. We can then plan effectively to make sure the child receives the help and support they need in areas they could find difficult

cultural identities. It seems like the difference between Black and African-American is that the first one was used more in political settings where they thought there was a need to separate or divide people by their skin color while African-American was used by people who still identify themselves with African‚ Still both terms were created to alienate one group from the other. As the reading explains the term black “Maintained that physical differences between the races account for social and

The Effect of Molecular Weight on the Diffusion Rate of Substances Jesselyn P. Rodriguez Group 4 Section X-2L August 13‚ 2013 ------------------------------------------------- ------------------------------------------------- ------------------------------------------------- ABSTRACT The effect of molecular weight on the rate of diffusion of substances is tested using two tests: the glass tube test and the agar-water gel test. In the glass tube test‚ two cotton balls were soaked

How reaction rate varies with sodium thiosulphate concentration Background information Sodium thiosulphate and hydrochloric acid are both colourless liquids‚ when the two reactants are reacted together they produce sulphur. The sulphur that is produced from the reaction changes the solution to yellow and cloudy‚ this is a precipitation reaction‚ where a two solutions react and a solid forms in the solution‚ the solid is said to precipitate out. Some reactions will occur quickly such as fireworks

Area P Write down the aim of your Investigation. To investigate the effects of change in concentration on the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid. Briefly describe your Preliminary Experiment and include your results. Explain how these results have helped you plan your main experiment (p8b). An increase in concentration will lead to an increase in the rate of reaction because there will be a greater number of particles per unit/cm3. The particles will be closer together

These pyramids took place in the Third Dynasty during 2630-2575 BC. King Djoser commissioned this monumental architecture in Egypt. The designer was Djoser’s prime minister‚ Ihotep‚ whose name is inscribed on a statue at the site. The purpose was to hold his mummified body. The Step Pyramid of Pharaoh Djoser’s at Saqqara arose as a traditional‚ flat-roofed mastaba‚ although in 2611 B.C.‚ by the end of his nineteen-year reign‚ it had risen to six stepped layers and stood two hundred and four feet

There are many differences in the composition and storage of genetic material in prokaryotes and eukaryotes. Chromosomes in prokaryotes consist of a single nucleic acid molecule which can be either DNA or RNA. There is comparatively little genetic material for example E.coli genome is 1200 micrometres while a single human chromosome is between 12000 and 73000 micrometers in size. Unlike in eukaryotes the genetic material in viral prokaryotes can be single or double stranded RNA or DNA. It can also
