Complete question -
The passage of the end products of digestion into the cells of an organism is an example
a) absorption
b) digestion
c) circulation
d) regulation

The blood stream carries the nutrient along with it and transport it to the brain, organs and other parts of the body as per their requirement.
Thus, option A is correct
Answer:
a) false
Explanation:
It is possible to sequence the entire genome, but not as one long molecule. By using the Massive parallel signature sequencing (MPSS), the latest technology available until now, the DNA is then fragmented into small pieces in order to be sequenced. In this technique, que marked sequences are obtained from several copies from cDNA and binded in long chains in order to create concatemers, which will be then sequenced.
