As for the feeding and nutrition a 4-5 month old infant formula-fed should consume a drinking formula milk of 8-10 oz per day, but as the above mentioned statement specify that formula-fed infant who needs approx 600 kcl per day, he should consume 32 ounces.
I think the answer might be A or B. Not so sure...
In changes the way it looks.
The cellular structure that was visible in the transmission electron micro graph but not visible in the cells when microscope was used is NUCLEOLUS.
The transmission electron micro graph is a microscopy method that involves using electrons beams to form image of specimens. Transmission electron micro graph can be used to view minute structures of the cell because of its higher optical capacity.
The nucleolus was not seen under the microscope because is a very small cell structure.
