Homologous :

a). Two of the homologous traits thats I believe are the same would be  Rabbits and Frogs.  Frogs and rabbits share similar bones in their bodies just like the rabbits such as humerus,radius and ulna. Although they both have different sets of bones they are both homologous.

b). The homologous traits of each of these species that they have in common would be forelimbs. Having forelimbs allow frogs and rabbits to do certain things in order to survive such as swimming, jumping and landing. Rabbits on the other hand need it for balance and hopping.
c ). The common ancestor of these two species would be a group of dinosaurs names is theropods

            



Analogous:

a). Two of the Analogous that I have chosen were parrots and butterflies. Parrot wing bones are very small but butterfly wings are completely different because their wings are rigid by fluid pressure. They might have some similarities but they are build with different structures which make them analogous. 

b). Both the butterflies and parrots have some similarities in structure and traits for example both the are able to fly and need this specific trait in order to survive. Both the butterfly and the parrots use their wings as a way to avoid predators if encountered they have the ability to go away.

c). Butterfly and parrots do not come from the same ancestor for many reasons but one specific reason would be because both of these animals don't have similar types of wings the butterfly for example comes from a family where their wings are tissue substances and parrots have different materials it makes them completely different in that aspect.

If I were stranded in an island and I was only able to take two things I would most likely take my phone and a boat. The reasons why I would take my phone would be just in case I am able to contact someone and send for help i would have the opportunity to call or send a message to someone if i were in that situation. If I was able to do that i would use it to keep me sane while I wait for help. I would also take a boat that will be able to take me to the nearest island where hopefully I can find people or a way to get back home. Not having any type of transportation I wouldn't have a way to go out there and look for help and I would just be stuck in an island without an opportunity to go back home until someone comes to find me.
