(03.05 LC) A student is measuring plant growth in an experiment. Using the same species of plant, he places one plant in the dark and one in artificial light. He hypothesizes that, over time, the plant in the artificial light will grow to a greater extent than that in the dark. What is the independent variable in this experiment? (3 points)

(03.07 HC)You are a forensic scientist on a case of a missing child. You are tasked with using genetic genealogy to determine if a child in custody is the missing child. Currently, you do not have a DNA sample from the child. However, the child has albinism, a recessive trait that is expressed as an absence of pigment in her skin and hair.Looking at the grandparents and parents of the missing child, you put together this pedigree. The shaded shapes mean the person has albinism. The open shapes mean a person does not have albinism or they are an unknown carrier of the disorder. The child in custody is represented with a shaded circle.Could the child in custody be the missing child?
