What is a specific example of competitive advantage exhibited by Darwin’s finches?(1 point) Birds have one of two forms of the HMGA2 gene.

Female finches mated with males that had similar-sized beak

All of the finches evolved from one ancestral species and adapted to their specific niche.

Medium ground finches with small beaks survived multiple droughts.

Ur answer is C. All of the finches evolved from one ancestral species and adapted to their specific niche.?

Explanation:

Because the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.

this website is for anybody really not just for girls just saying, also while a lot of males are mean and you know there are the few who are kind and then there's the nice-guys but then theirs also guys like me who are shy we don't get out much because there are people like you who exist who would most likely punch a guy in the face so next time just think about things before you post them to a website where guys and girls can see your question.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
