150 POINTSSS PLSS HELP HELP 150 POINTS PLS HELP Two different families asked a group of scientists for help in determining what type of genetic disease was in their families. The two different pedigrees are shown in the image.

Construct an argument based on evidence to determine which of the pedigrees, A or B, could be used to trace both an autosomal dominant and an autosomal recessive genetic disorder?

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)
