When an organism is diploid, that means it has _____. matching allele on the X chromosome. A power cycle operates between a reservoir at temperature TTT and a lower-temperature reservoir at 280K280 \mathrm{~K}280K.

The flow rate required to yield a specified reading on an orifice meter varies inversely as the square root of the fluid density; that is, if a fluid with density 1(g/cm3)\rho_{1}\left(\mathrm{g} / \mathrm{cm}^{3}\right)1(g/cm3) flowing at a rate V1(cm3/s)\dot{V}_{1}\left(\mathrm{cm}^{3} / \mathrm{s}\right)V1(cm3/s) yields a meter reading \phi, then the flow rate of a fluid with density 2\rho_{2}2 required to yield the same reading is V2=V1(1/2)1/2\dot{V}_{2}=\dot{V}_{1}\left(\rho_{1} / \rho_{2}\right)^{1 / 2}V2=V1(1/2)1/2 a) An orifice meter has been calibrated with nitrogen at 25C25^{\circ} \mathrm{C}25C and 758 mm Hg, but it now has methane flowing through it at 50C50^{\circ} \mathrm{C}50C and 1800 mm Hg. allele and one recessive allelle, the actual III. The genotype at loci A, B and C each produces a protein that influences the length of an organism by an average of 0.6, 0.4 and 0.3 cm, respectively. There are two types of molecular genes: protein-coding genes and noncoding genes. In biology, the word gene (from Greek: , gnos; meaning generation or birth or gender) can have several different meanings.The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA.
