What is known about the genus? Who discovered this species? When and where was your species first discovered? What makes your species a species (what is different about them, which character etc.)? What do we know about its distribution and habitat need

Which of the following is correct concerning the total number of ticks collected at each life stage for each species?   a:The highest number of adults were of D. variabilis and the highest number of larvae collected were of D. occidentalis.   b:The highest number of adults collected were of D. variabilis, and the highest number of larvae collected were of H. leporispalustris.   c:The highest number of adults collected were of D. occidentalis, and the highest number of larvae collected were of I. pacificus.   d:The highest number of adults collected were of D. variabilis, and the highest number of larvae collected were of I. pacificus.   article link:   https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0201665   I don't know what else should be included in my question, everything is in the article link that i attached

We have learned two geographical speciation modes - allopatric and sympatric. The example of frogs developed into two species at year 2500, right and left. Explain which geographic speciation mode led to these two species. Provide your reasoning using the information we learned from the class. *** (Picture is in my lecture slides):

T or F a)Quadrula and Radiatula each have glochidia that are unhooked – this must be a result of convergent evolution (e.g. homoplasy). b)The common ancestor of Parreysiinae mussels definitely had 'Unhooked' glochidia. c)Note that Mytilus, Mercenaria, and Neotrigonia are mussels that do not have glochidia larvae - they still have larvae, but they are distinct from the other taxa in this tree. Given this, it is unlikely that the common ancestor of all mussel taxa represented in this tree had glochidia larvae.
