Which of the following correctly lists the organ sand regions of he gastrointestinal tract in sequence after the stomach?
a. duodenum, jejunum, ileum, descending colon, transverse colon, ascending colon, rectum, anus
b. duodenum, ileum, jejunum, large intestine, anus, rectum
c. jejunum, duodenum, ileum, large intestine, anus, rectum
d. duodenum, jejunum, ileum, ascending colon, transverse colon, descending colon, rectum, anus

Option D, Duodenum, jejunum, ileum, ascending colon, transverse colon, descending colon, rectum, anus

Explanation:

The Duodenum, jejunum, ileum are the parts of small intestine and ascending colon, transverse colon, descending colon , rectum, anus are part of large intestine.

Basically after the gastrointestinal tract, the chyme enters into the small intestine where it passes through duodenum, jejunum, ileum. The shortest region is duodenum with length of 25.4 cm, while length of jejunum and ileum is 0.9 meter and 1.8 meter respectively.

After the small intestine the food enters the large intestine which has four major parts -

a) the cecum

b) the colon - it has three subdivision - ascending colon, transverse colon, descending colon (the food passes through) in given order

c) the rectum

d) the anus

Hence, option D is correct

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
