Some animals, but not humans, have an organ called a gizzard located near the top of their digestive tract. This organ is small and can contain small rocks. It also has thick, muscular walls. Based on this physical description, which of the following is most likely to be the function of this organ?
A.Chemical digestion
B.Mechanical digestion
C.Absorption of water
D.Absorption of nutrients*
i just took the quick sheck and i got 4/4 100%
the answers are:
1: C
2: A
3: B
4: D
B. Mechanical digestion.
b I had the same question
@UwU 4 ever
I correct!! 100%
Based on the physical description provided, the function of the organ described is most likely B. Mechanical digestion.
To arrive at this answer, let's break down the options and see how they align with the given information:
A. Chemical digestion involves breaking down food through the use of enzymes and other chemicals. Since the organ described - the gizzard - is described as having muscular walls without any mention of chemical secretions, it is less likely to be involved in chemical digestion.
B. Mechanical digestion involves physically crushing, grinding, or mashing food into smaller pieces. The gizzard, with its small size, muscular walls, and ability to contain small rocks, is well-suited for this function. The rocks in the gizzard help in grinding down the food, aiding in mechanical digestion.
C. Absorption of water occurs mainly in the large intestine, where water is reabsorbed from digested food. The gizzard, being located near the top of the digestive tract and described as having muscular walls, is not involved in water absorption.
D. Absorption of nutrients mainly occurs in the small intestine, where nutrients are absorbed into the bloodstream. The gizzard, described as a small organ with thick, muscular walls and containing small rocks, is less likely to be involved in nutrient absorption.
Therefore, the most likely function of the gizzard, based on the given physical description, is B. Mechanical digestion.
