Two insects in the same order are in the same . If two insect species are in the same family, are they in the same order? If two insect species are in the same order, are they in the same family? Do two insect species more likely have the most recent shared common ancestor if they are in the same family or in the same order? If insect species X and insect species Y are in the same family, and insect species Z is in a different family, which pair of species listed is more likely to have the most recent common ancestor?

The classification is as follow:

1-Class: Insecta

2-Order

3-Family

4-Genus  

5-Species

If two insect species are in the same family they share the same order, but not in reverse mode

Two insect species have the most recent shared common ancestor if they are in the same Family since this group is more inclusive than one defined by the Order  

If an insect species X and other insect species Y are in the same Family,  is more likely that X and Y have the most recent common ancestor compared than the insect species Z that is in a different family

i think it would be b. tissue because an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
