The most accurate disadvantage of using a dissected pig versus a 2D model of the human digestive system is:
A dissected pig’s inner structure is slightly different than a human’s.
This acknowledges that while the pig's digestive system is similar to a human's, there are anatomical differences that could affect the study or understanding of human digestion.

You observe a potted plant that has been tipped over. Initially, its roots had been pointing left, but after a few days, the roots began to grow downward.
Select the type of geotropism that is being exhibited and where auxin is accumulating in the roots.
(1 point)
Responses
negative geotropism; auxin is accumulating on the top side of the root
negative geotropism; auxin is accumulating on the top side of the root
positive geotropism; auxin is accumulating on the bottom side of the root
positive geotropism; auxin is accumulating on the bottom side of the root
positive geotropism; auxin is accumulating on the top side of the root
positive geotropism; auxin is accumulating on the top side of the root
negative geotropism; auxin is accumulating on the bottom side of the root

positive geotropism; auxin is accumulating on the top side of the root
positive geotropism; auxin is accumulating on the top side of the root
negative geotropism; auxin is accumulating on the bottom side of the root
The type of geotropism being exhibited is positive geotropism; auxin is accumulating on the bottom side of the root.
In positive geotropism, roots grow downwards toward gravity, and auxins accumulate on the lower side of the root, causing the cells there to elongate more than those on the upper side.
