Inner core
The inner core is the most dense layer of earth. The second next dense layer would be the outer core.
D. The large surface area of leaves allows for maximum light absorption.
Head moulding. Although, head moulding is common in any vaginal delivery, for a primigravid, which is having a child for the first time, is much more significant. The bones of a neonate are soft, flexible, and present gaps between them. These gaps and softness of the bones allow the moulding of the head when going through the vaginal canal. Being the first birth the vaginal canal is tighter and does not dilactate so well leading to a more significant head moulding.
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.
