Answer: seven
Explanation: the valence electrons are the numi of electrons found in the outermost shell of an element. The group of an element indicates it's number of electrons in the outermost shell while the number of shells occupied by electrons indicates the period.
Thus since the element is in group seven it has seven valence electrons.

Answer:
B. Molecular Systematics
Explanation:
First, let's review a few definitions. DNA, deoxyribonucleic acid: an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms, constructed of two nucleotide strands coiled around each other in a ladderlike arrangement with the side pieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine and pyrimidine bases adenine, guanine, cytosine, and thymine: the genetic information of DNA is encoded in a sequence of the bases and transcribed as the strands unwind and replicate. Molecular systematics is a scientific discipline that uses nucleic acids or other molecules to infer. evolutionary relationships between different species.
