The difference between the two students that we know of is that they used a different meter stick. So the difference would be best attributed to the different tools they used.
Note, this is quite a huge difference. It's likely that one of the sticks, or both, are quite defect.
Answer:
"As a molecule moves through the plasma membrane it passes through <em>a hydrophilic layer of phospholipid heads then a hydrophobic layer of phospholipid tails and then another hydrophilic layer of phospholipid heads".</em>
Explanation:
Biological membranes are formed by two lipidic layers, proteins, and glucans.
Lipids characterize for being amphipathic molecules, which means that they have both a hydrophilic portion and a hydrophobic portion at the same time. These molecules have a lipidic head that corresponds to a negatively charged phosphate group, which is the polar and hydrophilic portion. They also have two lipidic tails that correspond to the hydrocarbon chains -the apolar and hydrophobic portion- of the fatty acids that esterify glycerol.
Membrane lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane.
Through this lipidic bilayer, some molecules can move from one side of the cell to the other, which happens because of concentration differences. When this occurs, molecules must pass through the hydrophilic layer of phospholipid heads then through the hydrophobic layer of phospholipid tails and then again through another hydrophilic layer of phospholipid heads.
Antagonistic is the term for the phenomenon that occurs when two hormones present together to produce effects that are weaker than the effects of either one acting alone.
An antagonism, in ecology is an association between the organisms in which one benefits at the expense of the other. In Biology, it can be defined as A biological response to the exposure to multiple substances which is very less than would be predicted if the known effects of the individual substances were added together. For example, Your little sister or brother benefiting by disturbing you while you study.

Answer:
Stem cells are divided into 2 main forms. They are embryonic stem cells and adult stem cells. Embryonic stem cells.
Compared to other people, a person who has a "thrifty metabolism" GAINS WEIGHT MORE EASILY.
Thrifty metabolism is characterized by burning few calories for daily activities and leads to obesity. It might sabotage your weight loss plan as it utilizes very less calories. Apart for this there are other factors such as age and sex that also that affect the weight loss program.
