HELP IM SOOO CONFUSED Different leads are used to measure the ECG because

Select one:

a.

measurement of heart rate depends on which lead is used to measure it

b.

the signal has a larger amplitude on some leads so it is easier to measure

d.

the interval between ECG events differs on the different leads

e.

Suppose a particular species of tulip plant has three alleles for the gene that codes for flower color. the cr allele produces red tulips, the cp allele produces purple tulips, and the cw allele produces white tulips. cr is dominant over cp and cw, and cp is dominant over cw. for each of the following crosses, determine the expected ratio of offspring for each flower color. cr cp x cp cw cr cw x cp cw 1 red: 1 purple : 0 white, 1 red: 2 purple: 1 white, 2 red: 1 purple 1 white, 1 red: 3 purple : 0 white, 2 red: 0 purple : 2 white, 2 red: 2 purple : 0 white
