A person filters 720 millimoles of K in a day and secretes 42 millimoles. She excretes 75 millimoles in her urine. How much is K is reabsorbed, in millimoles

687millimoles

Explanation:

To calculate the amount of K reabsorbed in the kidney of an individual, we say:

Amount reabsorbed = Amount filtered + Amount secreted - Amount excreted

Based on the provided information,the respective amount of K is:

Amount filtered = 720 millimoles

Amount secreted = 42 millimoles

Amount excreted = 75 millimoles

Hence,

Amount reabsorbed = 720 + 42 - 75

Amount reabsorbed = 762 - 75

Amount of K reabsorbed = 687millimoles

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)

thats not even an aswer choice
