Since it is already answered, I am just coming to get the points (someone just stole mine recently lol). I hope you don't mind, and have a great day!
Answer:
C. Gene trees are only useful studying the relationships of sequences from different species.
Explanation:
Gene tree traces the evolutionary history of a particular gene. It includes all the events like duplication and speciation. It helps to study the relationship of genes from different species. Often these are orthologous genes which came form the same ancestor and code for the same protein indifferent species. Gene tree also helps to study the relationship of genes in the same species. Often these are paralogous genes which evolved by duplication and code for similar but not identical proteins in the same species. Hence, the statement that gene trees are only useful for studying the relationships of sequences from different species is incorrect.
Because of transcription. Transcription is the first step, where the RNA is synthesized.
Answer:
eat, lignite, bituminous, and anthracite.
Explanation:
The stage depends upon the conditions to which the plant remains are subjected after they were buried: the greater the pressure and heat, the higher the rank of coal.
