in \( f(x, y, z) \) from \( x=0, y=2, z=2 \) to \( x=\frac{1}{4}, y=1.9, z=2.1 \). Give your answer correct to 4 decimal places. 9. Let \( f(x, y)=x y^{1 / 2}+e^{2 x+y^{2}} \). Use total differential to approximate the change in \( f(x, y) \) as \( (x, y) \) varies from point \( (1,2) \) to the point \( (0.97,2.04) \). Give the answer correct to three decimal places.

NFKB regulates cellular responses to stress and damage including regulating the immune response to infection. In the absence of stimulation, a second protein, IKB, binds to NFKB blocking the nuclear import signal of NFKB so NFKB remains inactive in the cytosol. After stimulation by signaling pathways that sense cellular stress or infection, IKB is ubiquitinated and degraded, releasing NFKB. The nuclear localization signal of NFKB is unmasked when IKB is degraded leading to nuclear import of NFKB. Nuclear NFKB regulates transcription of genes that respond to the cellular stress or infection. Eventually NFKB is transported back to the cytosol to await the next cellular stress signal. The location of NFKB in cells under different conditions can be studied using immunofluorescence microscopy with an antibody that specifically binds NFKB. NFKB is mostly found in the cytosol in unstimulated cells and in the nucleus in cells stimulated with IL-1a. Which of the following would lead to decreased nuclear localization of NFKB after IL-1? stimulation? Choose one or more: A. The ubiquitination sites on IKB are altered so ubiquitination no longer occurs. B. Ran is bound to a nonhydrolyzable analog of GTP. C. Ran-GEF is kept in an active form in the nucleus. D. A large excess of a short peptide containing a nuclear localization signal is added to the cells.
