E.the number of amino acids in the protein
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.

Answer:</h2><h2>when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell .</h2>
Explanation:
Cell membrane is composed of phospholipid bilayer . Cell membrane is hydrophilic at the surface of outside of the cell and inside surface of the cell thus both surface of cell membrane is a hydrophilic . Interiorly cell membrane is hydrophobic or nonpolar region because membrane composed of long fatty acid chain interiorly . Inner surface of cell membrane have no contact with water or polar molecules . When membrane binds to each other then the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell , while nonpolar parts of cell avoid water and create bilayer phospholipid where hydrophobic tails are in between the hydrophilic heads .
