Ans. B. Hox genes.

Hox genes (homeobox genes) can be defined as a group of related genes, which specify regions of an body plan of an organism's embryo along its head-tail axis. Given figure represents body plan in fruit fly, in which has eight Hox genes, clustered into two complexes.

These genes include labial (for head involution),  proboscipedia (for labial abd maxillary pulps), deformed (maxillary and mandibular segments), sex combs reduced (for cephalic and thoracic development), antennapedia (pair of legs and wings), ultrabithorax (pair of legs halteres), abdominal-A and abdominal-B (for abdomen).

Thus, the correct answer is option (B).

Beriberi is caused by a deficiency of thiamine in the diet.
denis23 [38]

Answer:

Thiamine pyrophosphate  (derived from vitamin B1) is a coenzyme required for the activity of pyruvate dehydrogenase enzyme complex.

Explanation:

Pyruvate is the end product of glycolysis. During aerobic cellular respiration, pyruvate is oxidatively decarboxylated into acetyl CoA which in turn enters the Kreb's cycle. Oxidative decarboxylation of pyruvate is carried out by enzyme complex pyruvate dehydrogenase (PDH). The first step is simple decarboxylation and is catalyzed by pyruvate decarboxylase of the PDH complex.

The enzyme pyruvate decarboxylase and has a tightly bound coenzyme, thiamine pyrophosphate. Thiamine pyrophosphate is derived from vitamin B1. Lack of vitamin B1 in the human diet leads to beriberi that is characterized by an increased concentration of pyruvate in blood urine since oxidative decarboxylation cannot occur due to lack of the coenzyme thiamine pyrophosphate.
