Odonata ( but see Neuroptera)

Explanation:0

1) Does the insect have wings? YES >  GO TO 2)

2) How many pairs of wings does the insect have? TWO >  GO TO 3)

3) Does the insect have very short antennae? NO > Order Odonata.

Following the given dichotomus key, the insect belong to the order Odonata. However, there is an error in this key since Odonata does have short antennae, and according to this key odonata has short antennae.

Although in the attached image cannot be distinguished if there are five segments on each leg, the image seems to correspond to an insect within the order Neuroptera

Lactose is more likely to be utilised by E. Coli than Arabinose because Lactose will yield more energy (ATP) and lactose breakdown will give glucose and galactose and these will enter into the glycolytic pathways to pyruvate for ATP generation until Arabinose which will undergo Pentose phosphate pathway and this does not produce enough energy.
