was separated into four stages‚ the first being preparation of cell competency. In this stage two vials were placed in ice baths‚ one vial containing 50 µL of E. coli and the other containing a CaCl2 solution. 630 µL of the CaCl2 solution was then transferred to the E. coli vial‚ using a sterile pipet. After tapping the tube to mix the solution‚ it was then returned to the ice bath to continue incubation for at least 10 minutes. The cell competency preparation was carried out by the instructor in this

Based on the labs you completed‚ answer the following questions: 1. Which solute(s) were able to diffuse into the right beaker from the left beaker? Which did not? Answer: The solute(s) that were able to diffuse Na+/Cl- ‚ Urea‚ Glucose. The solute that didn’t was Albumin. 2. Explain the relationship between the rate of diffusion and the size of the solute. What do you think changes in temperature such as cold/hot would have on the diffusion rate? Answer: The rate of diffusion of molecules

CHAPTER 3 Response surface methodology 3.1 Introduction Response surface methodology (RSM) is a collection of mathematical and statistical techniques for empirical model building. By careful design of experiments‚ the objective is to optimize a response (output variable) which is influenced by several independent variables (input variables). An experiment is a series of tests‚ called runs‚ in which changes are made in the input variables in order to identify the reasons for changes in

Question 1 Surface level diversity Surface level diversity are those differences that are easily noticeable such as age‚ gender‚ ethnicity/race‚ culture‚ language‚ disability etc. Surface level diversity is easy to be measured and managers/recruiters can fall into the wrong practice of discrimination based on these factors. For example‚ thinking that performance degrades with age‚ they might prefer younger workforce. Surface level diversity is often difficult to change. For e.g. racial differences

photoshelter.com/image/I0000WDNZi_s2W4A Smarties Diffusion Experiment RESEARCH QUESTION How does changing the colour of smarties affect the extent of its passive diffusion? INTRODUCTION Passive diffusion‚ also known as simple diffusion‚ is used to describe the exergonic reaction of a substance where the substance passes in the direction of the concentration gradient. Most of the molecules move from the area of high concentration‚ inside the membrane of a cell‚ to the outside where there is a lower concentration

light intensity onto the leaf’s surface and the surface area of the leaf. Hypothesis I think the light intensity could affect the surface area in the following way: ·A higher light intensity could make the surface area of the leaf larger. The reason I think a higher light intensity could make the surface area larger is the fact that there would be a larger amount of chlorophyll‚ containing chloroplasts‚ for photosynthesis. By having leaves of a larger surface area‚ there would be a much more efficient

How does diffusion affect the rate of growth? If I placed a gummy bear in various solutions‚ then the gummy bear would change in size‚ because diffusion and osmosis cause the gummy bear to react to the solution’s molecules‚ and further affects the gummy bear’s mass. An experimental lab conducted in class was tested‚ essentially to observe the effects of diffusion/osmosis. More specifically‚ according to‚ “merriam-webster.com/dictionary/diffusion‚” the process of diffusion causes particles to spread

Depending on the cancer that one may have cancer cells have more chromosomes that are scattered which is for why cancer cells are formed. In cell division all living things obtain cells in which come from other preexisting cells. If normal cells are do not divide and make new cells then cancer will occur. In order of all cells to be
