Assume that endogenous acid production is 40 meq during a 12-hr period. A urine sample collected during this time contains 30 mmol NH4 and 15 meq titratable acid. If the body is in steady state for HCO3-, how much HCO3- must be in this urine sample?

Thus, the Quantity of Present in urine sample in 24 hours is 35mmol

Explanation:

Acid Production in 12 hours = 40 meq

For, 24 hours = 40 meq × 2

Acid Production in 24 hours = 80 meq

Urine sample for = 30mmol

Present in Urine Sample in 24 hours

= Acid Production - Urine sample for - Titratable Acid

= 80 - 30 - 15

= 50 - 15

= 35mmol

Present in urine sample in 24 hours is 35mmol

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)

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
