Which is a method of transmitting pathogens from one host to another by carrying microorganisms inside the body and hosting their survival until transmission has occurred

is this a psat question, if so do not cheat try your best.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.  

since there are no options posted i'll give you a few examples.

a dolphin's flipper, bird's wing, cat's leg.
