Question
Chapter 46, Problem 10TYU
Summary Introduction
To determine: Why motile species are less often hermaphrodites.
Concept introduction:
Hermaphroditism is a condition in which an organism has both male and female reproductive systems. They produce both male and female gametes, so any two organisms can mate. In hermaphrodites, the gametes produced by meiosis have different genetic makeup than the parent organism.

What is a dauer larva ?
It's a larva from a special variant of C. elegans that was first identified
in samples from soil in Germany
It is a larva that shows accelerated development in highly nutritious
environments
Dauer is just the technical term for "hermaphrodite" - so dauer larva
means hermaphrodite adult
It's a larva that arrests development in a low metabolic and enduring
stage, caused by harsh environmental conditions. The larva will
remain in the dauer stage until the conditions improve, at which
point they'll resume development.
In sea urchin, which step of egg and sperm recognition involves the formation of a fertilization cone?
Sperm binding to the egg's vitelline membrane
Fusion of the sperm and egg membranes
Acrosomal reaction
Chemo-attraction
Sperm binding to the egg's jelly coat
Annelida (Segmented round worms)
How do these worms differ from the other two?
What are the different classes of these worms?
Evolutionarily; what advances do we see with these worms over
the previous two groups?
What is a simultaneous hermaphrodite?
Define: setae, septa, parapodia

The parasite's life cycle is as follows: Hermaphroditic adults live in the small intestine cavity of an infected human. The adult worm consists of rings that are produced in the anterior region of the worm, in which there is production of male gametes which fertilize female gametes then these rings (called proglottids) detach from the posterior end of the worm and exit in the external environment through the anus of the infected human. The eggs resulting from fertilization, present in the proglottids, are released and can infect a bovid if they are ingested along with grass. In the bovid, the developing eggs are particularly localized in the muscles of the bovid and turn into a shape called a cysticercus (each egg becomes a cysticercus). 1-Specify which species is the definitive host of the parasitic worm, justifying your answer 2- Specify the type of parasitism of this worm, justifying your answer 3-Specify which is (are) the…arrow_forward
