Answer: a) hybridization of species, specifically parasites
Explanation:
Hybrid speciation is a kind of speciation that is caused by reproductive isolation from the parent species. In this the hybridization occurs between the two different species which leads to the formation of new species.
The hybrid formed because of the hybridization of the species that belong to the same genus called as interspecific hybrids and those formed between different sub-species are called as intra-specific hybrids.
Here, in the given situation, the hybridization of the different species of parasites due to geographical distribution of parasite due to global trade has resulted which is responsible for co-infections.
I just did this lesson in my school, If there were world wide educators on the subject, and/or a clean environment.
The lines often drawn on a map or globe that look like east/west paths are lines of constant latitude. The points on any one line are all at the same latitude, and there is a point on the line at every possible longitude all the way around the Earth.
Since the lines of constant latitude are all parallel to the Equator and to each other, they're often called 'parallels' of latitude.
