Answer:
Taxonomy
Explanation:
<em>Taxonomy is the science of identifying different organisms, living and extinct, by classifying and naming them. </em>To achieve this goal taxidermists consider genetics, biochemistry, behaviors, and morphology and resume this information into the species name. Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species are the taxonomic categories used from general to particular.
I hope you find this information useful and interesting! Good luck!

Answer:
B
Explanation:
We never see short bristle males, suggesting some type of lethality. I.e. any males who inherit the mutation die before birth so we don't see the phenotype. This also hints that it could be X-linked.
Females can be short bristled, but males can't, as it is likely lethal. This suggests that having one copy of the short bristle trait without the long bristle trait is lethal (as males as XY and so only have one copy of the trait). The female then must be heterozygous for the short bristle trait (which also explains how in generation F2, long bristle males can be produced, as if she was homozygous males would all be short bristled, and therefore dead, so there would be no males.
Since the first short bristle female is heterozygous, the trait for short bristles must be dominant.
However, since evidence suggests the trait is X-linked, it cannot be autosomal, as suggested in B.
Presence of nutrients is detected using various chemical reagents. Glucose is detected using Benedict's solution, while proteins are tested using the biuret reagent while lipids are tested using ethanol and water. In addition starch is tested using the Lugol's iodine. Therefore, the correct answer is 3 (starch- Lugol's iodine.
