An nrbc (nucleated red blood cell) is a mature erythrocyte. a. less mature than b. the same as c. more mature than d. from a different cell line than

A. 

Nucleated red blood cell is less mature than a mature erythrocyte. They are erythroid precursors that have apoptotic nucleus, the last nucleated stage of red blood cell production to contain a defined, intact nucleus before the erythrocyte losses its nucleus.

Moreover, they are confined to the bone marrow, in the peripheral blood in newborns and in uncompensated hemolytic anemia.

the fact that your name is twinkie makes me not wanna you at so im not

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
