The term which best describes the region "b" of the phospholipid model in the attached image (below) is: Hydrophobic.
Phospholipids are also referred to as phosphatides and they are a type of lipid whose molecule comprises the following:
- A hydrophilic "head" that contains a phosphate group.
- Two (2) hydrophobic "tails" joined by an alcohol residue and that are mainly derived from fatty acids.
This ultimately implies that, a large potion of the cell (plasma) membrane is made up of lipids, which are mainly phospholipids and they control the movement of large hydrophilic molecules such as alkanes, oils, and fats.
In conclusion, hydrophobic is a term that is used to describe the tail or lower part of a phospholipid model, which is the "b" region in the image attached below.

A is the answer I promise or b or c or d
A positive and a negative charge are released from rest in vacuum. They move toward each other. As they do: A positive potential energy becomes more positive.
For better understanding, lets explain the terms
- Electrical potential energy is positive and negative. If positive , it mean that the two charges are of the same type, that is, it is either positive or it is negative when the two charges are of opposite types
- A Positive potential energy means that work is done on a positive test charge so as to move it from one place to another, this result in the potential energy increases and also the electric potential increases
From the above we can therefore say the answer A positive and a negative charge are released from rest in vacuum. They move toward each other. As they do: A positive potential energy becomes more positive.

Considering the p-value of 0.6, the decision is that we do not reject the null hypothesis.
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, we test if the proportions are equal, that is:
At the alternative hypothesis, we test if they are different, that is:
<h3>What is the decision rule?</h3>
- If the p-value is greater than the significance level, we do not reject the null hypothesis.
- If the p-value is less than the significance level, we reject the null hypothesis.
In this problem, the significance level is of 0.1, while the p-value is of 0.6, hence the correct decision for the test is to not reject the null hypothesis.
