Discuss how does Newton's force (F) of gravitational attraction (F = G*[m1*m2]/r^2) between two water molecules (having a gravitational constant G = 6/67 *10^-11 N*m^2/kg^2 with masses m1 and m2) compare to van der waals attractive force? Assume a separation distance of r = 0.24 nm; water has a molecular mass of 18 g/mol; and van der waals attractive force is 1.6 pN, as previously calculated.
While working in a cell biology laboratory, you are instructed to create a solution that is iso-osmostice to the cells that the lab uses.
GIve the organizational levels in order, starting at the atom. Then, analyze how each level relates to specific functions and to each other.
Glycogen stored in muscles can be mobilized to supply metabolic energy by hydrolyzing individual glucose subunits from the polymer.
How may stomata density serve as a bioindicator for monitoring the response of plants to changes in greenhouse gas concentrations in the future.
An analyzer has two true breeding lines of rabbits, both of which are albino. Albinism is recessive in both lines. When the researcher crosses the rabbits,
Energy is stored in different forms in the body. ATP is very unstable and is put to use very quickly in cells. Other storage molecules last longer.
Consider the HIV enzyme called protease. The amino acid residues at the active site are highly hydrophobic. In designing a drug that would bind to the active site and jam it, researchers should use which sort of molecule.
Assume you isolate a mutant e.coli strain that is unable to grow without tryptophan supplementation at 37 degrees C but grows normally at 25 degrees C.
For each of the E. coli strains given below, estimate the effect of the genotype on expression of the trpE and trpC genes in the presence and absence of tryptophan.
Proportion of Australians aged twenty-five years and over with high blood pressure, by age group, 1999-2000. Note: High blood pressure is defined as systolic blood pressure of 140 mmHg or more;
Give details how those mutations can potentially result in cancer. Make sure you list all references used for information and images.
