Answer:
a. fats, oils, meats, and nuts.
Explanation:
Lipids are macromolecules that are insoluble in polar solvents like water, but soluble in non-polar solvents like diethyl ether. They made up of hydrocarbon and serve as a functional molecule in living cell membranes. In addition, they are involved in cell signaling and serve as energy stores. Lipids could be in the form of steroids, fats and oils, waxes and phospholipids.
In diets, oils, fats, nuts, meats whole milk, margarine, butter, cheese, fried foods supply lipids in large quantities. They serve as energy stores and also help in the absorption of fat-soluble vitamins in the small intestine.
<h2>Operational </h2>
Explanation:
The operational definition is the description of a specific process, or set of validation tests, accessible to more persons than the definer (i.e., said to be publicly accessible), where it can be repeatedly measured or tested
Operational definitions are also used to define system states or (nonspecific) physical objects by the description of a specific process of preparation which can be repeated
For example in the given example experimenter is using the case of hitting a punching bag to measure the level of aggression in someone
Tailings
Slurry is a liquid concrete or cement
Impoundments are enclosures of water
Answer:
A) Neither; they both have the same frequency.
It makes sense that cell membranes are made of phospholipids because water cant mix in with lipids, so the phospholipids will be able to effectively block out any unwanted water or chemicals suspended in water outside of the cell.
