Heterozygous parents would have the genotype Rr. In a punnett square, this would show a result of 25% homozygous dominant (RR) offspring, 25% homozygous recessive (rr) offspring, and 50% heterozygous (Rr) offspring.
(I attempted to simulate a punnett square with the text)

It would in fact be lethal. The main function of the digestive system is just that, to digest food. Both intestines play an important part in the digestive system( to digest and absorb all nutrients possible from stomach contents) The function of the large intestine is to absorb water, left over nutrients from the small intestine and, electrolytes. It would be equally if not more deadly if the small intestine couldn’t absorb nutrients. Since the small I intestine also plays an important role with providing the body with nutrients and other vital materials it would be deadly if you could not absorb anything. You would go into a state of malnutrition and would need to be treated immediately.
Answer: HORMONES
Hope this is correct :-)
The ratio of 
indicates the purity of nucleic acid.For pure DNA it should lie between 1.8-2.0.Whereas for RNA it should be greater than 2.
This is calculated for DNA using the given values of absorbance-
= 2.71
As the value is greater than 2.0,it reflects the RNA contamination in the sample.
