Answer:

Its location.

Explanation:

The main difference between pyrogenesis and setting garbage on fire in a landfill is that pyrogenesis process occurs on the surface whereas garbage on fire in a landfill occurs inside the soil at certain depth. Pyrogenesis is an extreme thermal process that converts organic matter into gas made up of hydrogen and oxygen whereas garbage on fire in a landfill decomposes garbage that breaks down materials in simpler substances.

Pachacha [2.7K]

Answer:

b) the plastic bag was permeable to iodine

the plastic bag was selectively permeable

the iodine moved into the plastic bag.

the plastic bag was permeable to cornstarch.

Explanation:

The experimental set up represented the concept of osmosis.That is  the movement of water  molecules from the region of higher  water potential to region of lower water potential through a semipermeable membrane(a  cell membrane which only allows water and certain molecules to pass through,but restrain other molecules through its pores.

Generally potassium iodine test is the standard test for starch.

Therefore, in the question,water moves iodine molecules as iodine solution(from high water potential) to move across the paper bag(semi permeable membrane) to the reach the corn solution.(low water potential,high solute potential).This turns the starch in the corn solution  blue-black/purple.
