I’m on that same question
Answer:
C. About 18 percent of the variation in blood pressure can be explained by a linear relationship between blood pressure and caffeine consumed.
Explanation:
Here, r = 0.428
∴ We can say it will give a positive curve, as 0.428 indicates it is a positive correlation.
Though the amount of correlation is low, still it is positive and more than 0.4
So, nearly about 18% of the variation in the blood pressure can be observed by the consumption of caffeine water. As consumption of caffeine water and blood pressure is both increasing so we can say that r= 0.428 will give a positive linear curve.

I don't get what you are trying to ask
The other is a result of ones radiation or sun exposure
The difference between the bonds that compose the hydrophobic hydrocarbon tail of a lipid molecule versus the forces that drive lipid droplet formation (the hydrophobic effect) is hydrophobic hydrogen tail of a lipid molecule is the non water loving lipid whereas hydrophobic is the effect which is known as non water loving effect.
<h3>What is hydrophilic meant?</h3>
If a molecule is the “water-loving”, it is known as the ‘hydrophile’ (noun) that possesses a hydrophilic nature. In the contrast, if a molecule doesn’t like water (h2o) i.e. repel the water, it is known as the ‘hydrophobic‘. The terms hydrophilic and the hydrophobic are used to describe the molecules or the substances based on how they react to the water molecules. The degree or the extent to which a molecule or a surface attracts water is known as the ‘hydrophilicity‘ of that molecule. Some of most common examples of the hydrophilic substances are sugar, salt, starch, and cellulose.
The tail of the phospholipid is the hydrophobic because it is composed of carbon and hydrogen atoms. If a molecule is made up of mostly of carbon and hydrogen atoms, it is a nonpolar or hydrophobic molecule. Carbon and hydrogen have the similar electronegativities, so they share the electrons equally resulting in the nonpolar bond. Because the tail of the phospholipid is the nonpolar, it does not interact with the water, whereas, Hydrophobic effect is just a tendency of non-polar molecules to come together so that they can avoid the water from their surface area as much as they can.
