Answer:
Option 2, Injection into a large muscle with the use of the Z-track method
Explanation:
The z-track method is used for parenteral iron preparations to avoid tissues from staining and irritation over the air lock method. Z track method prevents the leakage of medicine beneath the skin. In this method, after injecting the medicine the muscle and skin is pulled first and the injection is pulled later. This forms zigzag line that prevents medicine from leaking. Generally injected at thighs and buttocks
Hence, option 2 is correct
Most commonly, jello or any kind of gelatinous material is used when making a cytoplasm, while a nucleus is represented well with a plum.
Hardy and Weinberg’s work determining how allele frequency changes (C)
When glucose is high, cAMP is low; CAP does not bind the lac operator, and RNA polymerase does not bind the lac promoter. CAP is only active when glucose levels are low, which means the cAMP levels are high, and therefore the lac operon can only be transcribed at high rate when glucose is absent. The importance of this is that the bacteria only turns on the lac operon and start using lactose only after they have used up all the preferred energy source which is glucose.
