Answer:
The phosphate head of the phospholipid is hydrophilic because it is polar (having charge), and thus readily dissolves in water which is a polar solvent. The hydrocarbon chain tails of phospholipid are hydrophobic because they are nonpolar (uncharged), and thus remain undissolved by water. These hydrocarbon tails have an affinity for each other, orienting themselves to face each other in water, forming the hydrophobic …

The control group is the group that does not receive the experimental treatment. Experimenters use the control group to compare it to the experimental group in order to determine if the treatment had an effect. So, if there is the same result in both groups (decrease in the grass blades) it means that the given treatment had no effect on the experimental group and that the decrease is due to some other conditions.
