Arrange the following structures in order from the small intestine to the rectum. (1) ascending colon (2) descending colon (3) s
Hitman42 [59]

Answer: in order from small intestine to the rectum: 1, 4, 2 and 3.

Explanation: Ascending colon; the colic valve(the ileocecal valve) is located at the bottom of the ascending colon. At the top of the ascending colon, the colon bends to the left, forming the right colic flexure called the hepatic flexure. The transverse colon begins after this flexure.

The transverse colon; is the longest and most movable part of the colon which runs across the abdomen from the ascending colon at the right colic flexure with a downward convexity to the descending colon, here it curves abruptly on itself under the lower end of the spleen to form left colic flexure called the splenic flexure.

Descending colon; it start from the splenic flexure to the beginning of the sigmoid colon. The descending colon stores the remnant of digested food that will be deposited into the rectum.

Sigmoid colon; also known as pelvic colo is the closest to the rectum, it is a passage by which digested food move into the rectum.

One of the most common methods of differentiating between early hominid stages of human evolution is through examining what?
REY [17]

The early hominid stages can be differentiated from one another based on the complexity of the tools used by these species. The tool evolved along with the evolution of the humans. The more the hominids evolved by more complex their tools became.  The tools made by the earliest hominids were used to fish out the termites. These tool developed and became more widely used as the humans evolved.

Hence, the answer is 'by observing the complexity of the tools'.

Gluconeogenesis shares some, but not all, enzymes with the glycolytic pathway. It would appear to be more efficient if both path
viva [34]

Answer:

D) Three of the reaction steps in gluconeogenesis would have prohibitively large, positive free energies if they used glycolytic enzymes for their catalysis.

Explanation:

The glycolytic enzymes catalyze the conversion of glucose to pyruvate, while gluconeogenesis enzymes catalyze the formation of carbohydrates from pyruvate.
