A True breeding Wild type fly was crossed with a True breeding Mutant fly to produce a Heterozygous F1. An F1 female was then crossed to a Test male. The results of this cross are as follows: cn vg 4202; cn 458; rd 4258; rd vg 482; cn rd 28; Wild Type 276; vg 32; cn rd vg 264. Which Phenotypes represent the Parentals i. s., the non- Cross Over Phenotypes from the F1 generation

air enters through the nose, moves through the nasal cavity, the pharynx, the larynx, enters the trachea, moves through the bronchi andbronchioles till the alveoli.

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
