Apopulation of rodents, called population a, lived together in harmony on a large landmass until one group of the population dispersed to a nearby island. two million years later, the island population is split into two smaller, equal-sized populations when a river formed across the middle of the island. now two new species have evolved on the island, a1 and a2. they have replaced the population from which they were derived. which represents the phylogeny of the three extant species discussed in this scenario?

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.  

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community

explanation:

i do believe the correct answer would be the third one. location c, because earth is tilted away from the sun at this time

hope this
