kd ingnd r w Same whr h ai 4 After 24 hours, check to see if the egg shell is dissolved by gently taking out each egg and rinsing with a small amount of water. The eggs should have a yellow tint to them and you should be able to lightly squish the egg between your fingers (Figure 2). BE CAREFUL TO NOT BREAK THE EGG s If any of the eggs still have a hard shell after 24 hours, allow the eggs to sit for another 12-24 hours. Be sure to add fresh vinegar to the egg to ensure complete removal of the shell. Once the egg shells have been dissolved, remove them from the vinegar. HANDLE EGGS CAREFULLY THEY CAN EASILY BREAK. Rinse out and dry all four beakers. sLabel the four beakers “100% distilled water,””100 % com syrup solution,””10% corn syrup 90% water solution,” and “control.” In the beaker labeled “10%% corm syrup 90% water solution,” prepare a 10 % sugar solution by mixing 45 mL of distilled water with 5 mL of corn syrup. Mix well with a stir rod. Record the initial volume in Table 1. In the beaker labeled “distilled water,” measure and pour 50 mL of distilled water. Record the volume in Table 1. The egg should be covered. Add or reduce the amount of water if necessary. Record the initial volume in Table 1. In the beaker labeled “100% com syrup solution,” measure and pour 50 mL of con syrup (100% sugar solution). The egg should be covered. Add more corn syrup if necessary. Record the initial volume of the solution in Table 1. 12 In the beaker labeled “control,” do not add any solution. Record the volume in Table 1. ts Add one egg to cach bcaker and cover with foil 14 Let the eggs sit for 24 hours. In the meantime, develop a hypothesis stating how you believe each egg will be affected by the solution in the beaker over the 24 hour period. Record your hypothesis in the Post-Lab Questions section 15. After 24 hours have passed, observe the eggs. If you do not see any noticeable difference, let the eggs sit for another 12-24 hours. 16 After the eggs have rested for 24-48 hours in the solutions, carefully remove them from the beakers Make sure to note which eggs came from cach beaker Be careful to not spill the solutions 17.

Which of the following is/are true regarding observed effects of pH on enzyme activity and rate, and the underlying causes of these effects? Choose one or more: All enzymes exhibit their fastest rate of reaction at an approximate physiological pH of 7.4, as all organisms maintain a pH range very close to this in order to avoid alkalosis or acidosis. b a The rate of an enzyme-catalyzed reaction will slow down when outside the optimal pH range of the enzyme. The active site of an enzyme can change shape and overall charge when pH is not optimal, possibly reducing the enzyme’s activity. Most enzymes will display the same reaction rate across a broad range of pH levels due to the flexibility of the active site. C d. 5. You have a mystery hormone (agonist), and to test the nature of the agonist you add it to a dish of cultured liver cells. Shortly afterward you observe an increase in protein kinase activity.

haploid strains of yeast -one with the genotype A Lq and the other performed between two A cross was of genotype a 1 Q. The A, L and O loci are all tightly linked, with the L locus placed between the A and Q loci. Transient diploid cells formed, and these underwent meiosis to produce spores contained in tetrads. Of the many tetrads produced from this cross, one tetrads was identified containing spores of the following genotypes: al Q ALq, AlQ alg The molecular events of recombination thought to follow the double-strand break model. For this are question, you do not need to explain how the heteroduplexes arose, but do need to discuss later relevant events a) Draw a labelled diagram of the Holliday intermediate stage of the double-strand break model of recombination.
