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.
Intermediate-acting insulin. What itâs called: Humulin N (NPH), Novolin N (NPH) Intermediate-acting insulin can control blood sugar levels for about 12 hours or longer, so it can be used overnight. It begins to work within one to four hours, and peaks between four and 12 hours, depending on the brand.
