When hypothesizing a possible phylogeny in order to classify taxa, scientists incorporate systematics to A)provide primarily morphological information.
B)provide molecular or genetic information, as well as morphological information.
C)name organisms using a genus and specific epithet.
D)create a hierarchy of classification based upon reproductive mating patterns.

B)provide molecular or genetic information, as well as morphological information.

Explanation:

Systematics is the science of classification and phylogeny reconstruction. Studies diversity as a consequence of evolutive history and establishes the bases to reconstruct biological patterns and formulate hypotheses to explain the processes of these patterns. It reconstructs the origin and diversification of a taxon. Systematics creates systems of classification represented in a tree. Taxonomy is based on systematics.

The main goal of systematics is to solve the genealogical relationship between different species and biological groups that produces natural clusters.

Systematic considers morphological characters, as well as physiological, cytological, molecular, and behavioral characters.  

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.
