1. Based on the examples in the table, how do opinions differ from facts?
baherus [9]

1. Opinions are not always right; facts are.

2. Theories are sometimes right, but sometimes they are either wrong or a little off; facts are on point and with the exact answer.

3.  A theory is a scientific explanation of a fact.

4. They all have a good amount of information; also they say approximately to let you know it's not the exact answer.

5. A law is more like a prediction of what will happen if the situation is given and it's shown by the mathematical equation; Theory describes what happens. (Happened).

6. This would try to go against my understanding but it won't happen because I know that theories don't become laws or vice-versa; theories remain theories and law remain laws.

Explanation:

C. They make it more fluid

Lipids are composed of fatty acids which form the hydrophilic head and glycerol which forms the hydrophilic tail; their arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.

The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Cholesterol, which is comparatively rigid, anchors other molecules attached to the membrane, maintain membrane stability or structural integrity  and aid in separating some lipids, helping with membrane fluidity at low environmental temperatures.
