Question

The advantage of hermaphroditism in Hirudo is
A. To produce a double population
B. To decrease population
C. To increase population
D. None of these

Answer 1

Hint: Hirudo is a leech that lives indefinitely in freshwater and is segmented, or so they specifically thought. It is hermaphroditic, meaning it particularly has both sort of male and generally female sex organs that kind of produce kind of male and particularly female gametes. The advantage of this hermaphroditism to Hirudo is to essentially produce a pretty double population subtly.

Complete answer:
Leeches mainly are protandric hermaphrodites, with the certainly male reproductive organs, the testes, maturing first and the ovaries later in a for all intents and functions big way The penis for the maximum element passes a spermatophore into the virtually female gonopore and sperm more often than not is transferred to, and probably stored in, the vagina, which suggests that leeches are protandric hermaphrodites, with the male reproductive organs, the testes, maturing first and the ovaries later, which is fairly giant. Some jawless leeches and proboscis less leeches lack a penis, and in these, sperm is passed from one individual to another by hypodermic injection. The sperm generally is liberated and for all intents and purposes passes to the ovisacs, either through the coelomic channels or interstitially through specialist "target tissue" pathways in a for all intents and purposes major way. Producing a pretty particularly double population subtly is the advantage of leech, kind of contrary to popular belief.

Hence, the correct answer is option A. Produce a pretty particularly double population subtly is the advantage of leech.

Note:
Leech any of about 650 species of segmented worms characterized by a small sucker, which contains the mouth, at the anterior end of the body, and a very large sucker located at the posterior end, which is quite significant. All leeches have 34 body segments in a fairly big way.
