Illustrate in the form of a Punnett square the results of crossing a pink-flowering four o'clock with a white-flowering four o'clock. Students should place symbols representing one parent's alleles (Rr) on the left side of a four-box square and those representing the other parent's alleles (rr) across the top. Students should fill in each box with the appropriate two symbols. The boxes reveal all possible genotypes. (Rr, Rr, rr, rr)
Figure 1: Structural formula of Novolin R. Novolin R is a sterile, clear, aqueous, and colorless solution that contains human insulin (rDNA origin) 100 units/mL, glycerol 16 mg/mL, metacresol 3 mg/mL, zinc chloride approximately 7 mcg/mL and water for injection. The pH is adjusted to 7.4. Hydrochloric acid 2N or sodium hydroxide 2N may be added to adjust pH.
1 For example, if you need five units of NPH and two units of Novolin R, the total dose of insulin in the syringe would be seven units. 2  Roll the NPH vial between your hands until the liquid is equally cloudy throughout. 3  Draw into the syringe the same amount of air as the NPH dose.ifferent insulins should be mixed only under instruction from a health care provider. Do not mix Novolin R with any other type of insulin besides NPH insulin. Novolin R should be mixed only when injections with syringes are used.
