A cell wishes to import glucose from its environment. For each mode of transport noted below indicate if that is not transport is a potential option for the cell. If the mode of transport is not an option, indicate why this mode is not an option. If the mode of transport is an option, explain when this mode would be useful.

When comparing an E.coli wild type bacteria to its mutant strain, A t-test was used to compare their antbiotic susceptibility. The "p" value of the T-test was 0.497. In comparison, another mutant was compared to the wild type and the "p" value was 0.385. 1- How would you describe the differences between the wild type and mutant? 2- If there is a "p" value of 1, does that suggest a significant difference between wild type and mutant?

Why does 0.01M KMnO4 not change color at first when it is added to 0.025M of Na2C2O4 (sodium oxalate)? I did a titration of KMnO4 and Na2C2O4 a week ago and initially when I added the KMnO4, it turned the sodium oxalate a deep purple. It later turned colorless after about 15 seconds. Why is that? Is there a reasonable explanation?

Recall that Carson Company relies heavily on commercial banks for loans. When the company was first established with equity funding from its owners, Carson Company could easily obtain debt financing because the financing was backed by some of the firm’s assets. However, as Carson expanded, it continually relied on extra debt financing, which increased its ratio of debt to equity. Some banks were unwilling to provide more debt financing because of the risk that Carson would not be able to...
