Which enzymes are secreted only by the pancreas?
a_sh-v [17]

Nucleases are the enzymes that are unique to the pancreas. These are enzymes which break down nucleic acids DNA and RNA into nucleotides. When these nucleotides reach the ileum, they are further degraded or digested into sugars, bases and phosphates. These nucleases are known as DNAase and RNAase

Other pancreatic enzymes such as amylase and protease are also produced by other digestive organs such as the salivary glands and the small intestine respectively. However no other digestive organ has been known to produce nucleases apart from the pancreas.

Nucleases are of two  main types, namely exonucleases which cut off the end of a nucleotide and endonucleases which will cut out certain nucleotide sequences right in the middle of a nucleic acid.

The average person blinks 25 times per minute how many times do they blink per year
Serggg [28]

If the average person blinks 25 times per minute you have to multiply and times it by 60(which is an hour) to equal {1,500} . Next times the number 1,500 by 24 because that is how many hours are in a day so that would equal {36,000} times a day. Now times 36,000 by 7 because that is how many days of the week so {252,000} is the answer per week.


Now to figure out how many times we blink in a year we will multiply

252,000 by 52 because there are 52 weeks in a year.


You get the answer 13,104,000


So you blink 13,104,000 times in a year.


Hope this helps
