Please help! Cladograms represent hypotheses of relatedness based on evidence. When cladograms are constructed from molecular evidence, scientists must examine genes to determine placement. What key factor should scientists look for when determining relatedness between species using this type of evidence? Biochemical pathways
Mutations to homologous genes
The pattern of embryological development
Morphology

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
