You again want to map the positions of three genes (l, m, and n) in drosophila. each gene has one dominant allele and one recessive allele. you perform the three different two-fac- tor crosses (cross 1: lm and lm, cross 2: mn and mn, and cross 3: ln and ln). assume all crosses are between diploid flies homozy- gous for the alleles of these genes. you observe 5% recombinants in the first cross, 50% recombinants in the second cross, and 50% recombinants in the third cross. based on the data given, what can you determine for the gene order and distance between the genes?

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

not sure if this is what you'r looking for eubacteria and archaebacteria

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
