If the mass ratio of magnesium to magnesium oxide is 0.455 g/ 0.755 g what is the ratio to oxygen to magnesium oxygen by mass

(6 pts) Draw a rough sketch (gene locations including resistance genes, gene directions for insert and origin of replication, promoter) of five common plasmids that could result from the “dirty” ligation that we performed. (5 pts) You must assume that not all the enzyme reactions were 100% effective. Indicate which ones of these plasmids you would observe if performing not “dirty” but “clean” ligation. (1pt.)

If a neurons resting membrane is around -70mV, it is likely that, in addition to potassium leak channels this neuron has a leak channels permeable to another type of ions, such as sodium ions

Every single male for an entire lineage is affected with this disorder or disease. No females are affected with it. What type of inheritance system does this suggest? Y-linked X-linked Autosomal dominant Autosomal recessive

Person A has a dominant trait and person B has a recessive trait. They mate and half of their offspring have the recessive trait. What genotype is possible for their offspring with the dominant trait? TT only TT or Tt tt only Impossible to tell from this information. Tt only
