Erythropoietin stimulates production of haematids in the treatment of anaemia.

Mycoplasmas or mollicutes are the simplest and smallest of all the free living prokaryotes. Due to the absence of a cell wall, these organisms can change their shape and are pleomorphic.

Polyembryony is the phenomenon of two or more embryos developing from a single fertilised egg. Polyembryony occurs regularly in many plants and animals. Polyembryony is more common in gymnosperms than in angiosperms.

The operon consists of a series of structural genes, a segment of DNA called operator, adjacent to the structural and next to the operator and an additional DNA segment called the promoter. Elsewhere on the chromosome there is a segment of DNA called regulator gene.

The Enter-Doudoroff pathway is an alternative pathway of glucose metabolisms. It is found in aerobic and anaerobic prokaryotes (especially in Gram negative bacteria) but not found in eukaryotes.

The term amphibolic is used to describe a biochemical pathway that involves both catabolism and anabolism. The Tricarboxylic acid cycle (TCA cycle or Krebs Cycle) is a good example of the amphibolic pathway. The first reaction of the cycle, in which oxaloacetate (a four carbon compound) condenses with acetate (a two carbon compound) to form citrate (a six carbon compound) is typically anabolic. The next few reactions, which are intramolecular rearrangements, produce isocitrate. The following two reactions are typically catabolic. CO₂ is lost in each step and succinate (a four carbon compound) is produced.

Standard free energy change of hydrolysis of 1,3-diphosphoglyceric acid is 11.8 kcal mol^-1.

Cuttlefish (Sepia) and Devil fish (Octopus) are false fishes belonging to phylum Mollusca.

Tape worm (Taenia solium) is a false worm belonging to Phylum Platyhelmithes. Silk worm (Bombyx mori) is a false worm belonging to Phylum Arthropoda. Earth worm (Pheretima posthuma) is a false worm belonging to Phylum Annelida.

Aggregation pheromones help in making the group of the animal of the same species. Gerdiol is an aggregation pheromone of honey bee.

When two hormones work together these are known as synergesic hormone. Ex. – FSH and LH.

Fe is in +3 oxidation state in transferrin as well as ferritin.

Koch’s disease is also known as Tuberculosis (TB) is a potentially fatal contagious disease that can affect almost any part of the body but is mainly an infection of the lungs. It is caused by a bacterial microorganism, the tubercle bacillus or Mycobacterium tuberculosis whereas Leprosy, also known as Hansen's disease (HD), is a chronic infection caused by the bacteria Mycobacterium leprae and Mycobacterium lepromatosis.

Within cells, iron is stored in a protein complex as ferritin. Ferritin is a intracellular protein that stores iron and releases it in a controlled fashion. Iron circulates in plasma bound to transferrin (which can bind one or two iron molecules).

It is the correct answer. Clove is the dried flower bud of Syzygium aromaticum. Coir fibre is obtained from the mesocarp of the coconut fruit (Cocos nucifera). Litmus is an acid base indicator obtained from lichen Rocella tinctoria. Saffron is obtained from the style and stigma of the flower Crocus sativus.
