2. The LDL used in today's experiments was oxidized by incubating native LDL in 10 MM CuSO4 at 37°C for 24 hours with gentle rotation. The molecular weight of CuSO4.5H20 is
249.68. How much CuSO4.5H20 would you need to add to 4 ml of the LDL solution? Is
weighing out this much CuSO4.5H2O possible? If not, how would you get the desired
concentration of CuSO4 in your LDL solution?

In what way do investigations build scientific knowledge? the results of investigations lead to questions that cannot be tested. they reflect the opinions and social values of scientists, ensuring valid information. the results of investigations lead to new questions, which lead to new investigations. they are not influenced by the research of earlier scientists, so they are able to address gaps in understanding. i
