a. One
b. Two
c. Four
d. Six

Answer 1

Entamoeba histolytica is an anaerobic parasite. It is a parasitic protozoan. E. histolytica belongs to the genus Entamoeba. It mainly infects human beings and other primates which cause a dangerous syndrome called amoebiasis.

Complete answer:

Entamoeba histolytica is a type of Gram-negative anaerobic parasite. E. histolytica is part of the genus Entamoeba and it is a coliform bacteria. This amoebozoa is considered a pathogenic protozoan that infects humans and other primates. This infection is associated with intestinal and extraintestinal infections which is a dangerous syndrome called amoebiasis.

Entamoeba histolytica is contaminated with cysts. Cysts are passed in feces and they are generally found in the formed stool. The infection caused by Entamoeba histolytica occurs due to the ingestion of mature cysts. The transmission of E. histolytica takes place through food or water.

Entamoeba histolytica life cycle consists of a cyst stage and a trophozoite stage. The trophozoite matures into a tetra-nucleated cyst. A mature cyst of E. histolytica is a tetra-nucleate cyst and divides twice. The cyst bears four nuclei and two chromatid bodies found in the cyst. This tetra-nucleate cyst is the infective stage. Generally, a cyst of Entamoeba histolytica produces only one young amoeba.

It is reported that, generally, E. histolytica infects about millions of people worldwide. The word histolysis refers to the disintegration and dissolution of organic tissues.

Hence, the correct answer is option (A).

Additional information:
Entamoeba histolytica is a protozoan and pathogenic in nature. A parasitic type of nutrition is noticed among the genus of Entamoeba. The parasite E. histolytica has generally possessed one pseudopodium and the contractile vacuole is not found in them because osmoregulation is not required for this type of parasite. Entamoeba histolytica caused damages to the wall of the large intestine and It feeds on red blood corpuscles then reaching to the blood capillaries. It produces ulcers. It is found in the upper part of the human large intestine.

Note: Entamoeba histolytica is a type of anaerobic protozoan, which is a parasite in nature. It is associated with its intestinal and extraintestinal infections. This infection in humans causes a dangerous infection called amoebiasis. This amoebozoa belongs to the genus Entamoeba. Generally, it is contaminated through the cyst which is transmitted through the food and water. A cyst of Entamoeba histolytica produces only one young amoeba.
