Saturated fatty acids are different to unsaturated fatty acids because they?
saul85 [17]

Saturated fatty acids are different to unsaturated fatty acids because they have no C=C double bonds.

<h3>What are the differences between saturated and unsaturated fatty acids?</h3>
  • Saturated fatty acids do not have C=C double bonds, while in unsaturated fatty acids there is at least one C=C double bond in the fatty acid chain.
  • Saturated fats are usually solid at room temperature and are derived from animal sources, whereas unsaturated fats are usually liquid at room temperature and are from plant sources.
  • One must reduce the amount of saturated fat in their diet and consume more unsaturated fats like olives, seeds and nuts.
  • Unsaturated fats can be monounsaturated (contains only C=C double bond) or polyunsaturated (contains two or more C=C double bonds).

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.

Answer:

For example, the respiratory and circulatory systems work together to provide the body with oxygen and to rid the body of carbon dioxide. The lungs provide a place where oxygen can reach the blood and carbon dioxide can be removed from it. Each of your body systems relies on the others to work well. Your respiratory system relies on your circulatory system to deliver the oxygen it gathers, while the muscles of your heart cannot function without the oxygen they receive from your lungs. ... Your circulatory system delivers oxygen-rich blood to your bones.
