A parasitic organism is one that benefits from its host, but doesn't benefit the host, in fact, it has negative effects to the host.

In this case, we have 4 examples of worms, and we're supposed to find the parasitic one. And, I think this is something we can do without having to go deep into the subject, because at first sight, we can distinguish a worm, that we all know isn't paricularly good - leeches.

→ Leeches are an example of parasitic annelides that live in high-humidity environments, and live partly from the blood they suck from animals and sometimes humans.

Hope it helped,

In general, the frequency of crossing over between two linked genes depends on what?
mrs_skeptik [129]

Answer:

Crossovers during meiosis happen at more or less random positions along the chromosome, so the frequency of crossovers between two genes depends on the distance between them.

The closer two genes were to one another on a chromosome, the greater their chance of being inherited together. In contrast, genes located farther away from one another on the same chromosome were more likely to be separated during recombination.
