Answer: The answer is neutralizes acid entering from the stomach into the duodenum.

Explanation: Bicarbonate secretion is a base and critical to neutralizing the acid coming into the small intestine from the stomach. This mechanism explain bicarbonate secretion is essentially the same as for acid secretion by parietal cells in the stomach and is dependent on the enzyme carbonic anhydrase.

A particular triplet of bases in the template strand of DNA is 5' AGT 3'. The corresponding codon for the mRNA transcribed is __
earnstyle [38]

Answer:

The correct answer is 3' UCA 5'

Explanation:

The rule of pairing of base-pair says that A and T base pairs with each other with two hydrogen bonds and G and C base pairs with each other with three hydrogen bonds in DNA. In the case of RNA Uracil comes at the place of thymine that means uracil replaces thymine.

Therefore according to this base-pairing rule the corresponding codon of mRNA transcribes from DNA codon 5' AGT 3' will be 3' UCA 5' as U came in place of A nucleotide, C comes in place of G nucleotide, and A comes in place of T nucleotide.  

Therefore the correct answer is 3' UCA 5'.

larisa [96]

Answer:

No, the lack of short-tailed animals in the sample does not suggest that the population is out of Hardy-Weinberg equilibrium in this forest. It probably means that individuals with short tails were not included in the sample by chance, as their expected frequency in the population is considerably low.
