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.
The role microbiologists can play in reducing the number of Parasitic helminths infections is to create public awareness for environmental and personal hygiene.
<h3>What is Parasitic helminths infections?</h3>
These are infections that are caused by parasitic helminths.
The role microbiologists can play in reducing the number of Parasitic helminths infections is to create public awareness for environmental and personal hygiene.
This infection can be diagnosed through stool analysis in a laboratory and antihelminth drugs can be given such as albendazole for the treatment.
