When comparing the birth patterns of humans and non-human primate, Rosenberg and Trevathan discovered some very clear differences:
1. The human period of labour and child birth is exceptionally long and painful compared to other non-human primates.
E.g. a human labour can last anywhere from 10-20 hours while that of a chimpanzee lasts only 2 hours.
2. Humans have the ability to walk straight, the trade off however is that it is extremely difficult and painful to give birth to a big brained human baby.
4^3 = 64
There are 64 ways to arrange the four bases (Adenine, Thymine, Cytosine, and Guanine) into triplets (include repeats of bases as well, for e.g. AAT).
Just in case you are confused by my use of Thymine above, one thing to note is that Thymine will be replaced with Uracil in RNA.
Hope this helps! :)
The answer to this question would be: <span>producing large quantities of proteins for secretion.

A cell with many rough endoplasmic reticulum has a high protein synthesis capability. This will make the cell able to produce many proteins like enzyme. One example of this type of cell will be pancreas cells. This cell will need many enzymes to digest food that you eat so it will need many ER to produce it.
The region of the body that will be examined is the EPIGASTRIC REGION.
The epigastric region refers to the upper central region of the abdomen. Its exact location is in-between the coastal margin and the sub - coastal plane.
