Question

select the correct answer from each drop - down menu. fats obtained from a variety of foods are essential nutrients but may be harmful to the body in some forms.
______ are fats that have at least one double bond in the fatty acid chain. most
______ are artificially hydrogenated fats that have detrimental effects on health.

Explanation:

To solve this, we analyze the types of fats:

1. For the first blank: Fats with at least one double bond in the fatty acid chain are unsaturated fats. But the sentence says "Most [blank] are artificially hydrogenated fats...". Artificially hydrogenated fats are trans fats (which are a type of unsaturated fat that's been hydrogenated, but the key here is that trans fats are the ones with harmful effects and often artificially hydrogenated). Wait, correction: Unsaturated fats have double bonds. But the second part about artificially hydrogenated fats refers to trans fats (which are made from unsaturated fats via hydrogenation, but trans fats are harmful). Wait, no—let's recall:

• Unsaturated fats (monounsaturated or polyunsaturated) have one or more double bonds. They are generally healthy (like olive oil, omega - 3s).
• Trans fats: These are often artificially hydrogenated unsaturated fats (to make them more solid, like in margarine). Trans fats are harmful.

Wait, the first sentence: "Fats obtained from a variety of foods are essential nutrients but may be harmful to the body in some forms. [First blank] are fats that have at least one double bond in the fatty acid chain. Most [second blank] are artificially hydrogenated fats that have detrimental effects on health."
Wait, no, maybe the first blank is "Unsaturated fats" (since they have double bonds) and the second blank is "Trans fats" (since trans fats are artificially hydrogenated and harmful). Wait, but let's re - read:
The first part: "__ are fats that have at least one double bond in the fatty acid chain." That's unsaturated fats (mono or poly). Then "Most __ are artificially hydrogenated fats that have detrimental effects on health." Trans fats are the ones that are artificially hydrogenated (converting unsaturated fats to trans fats, which are harmful). So:

• First blank: Unsaturated fats (because they have double bonds)
• Second blank: Trans fats (because they are artificially hydrogenated and harmful)

Wait, but maybe the options (not shown here, but from typical questions) are:
First drop - down: Unsaturated fats (since they have double bonds)
Second drop - down: Trans fats (since they are artificially hydrogenated and harmful)
Alternatively, maybe the first is "Saturated fats" no, saturated have no double bonds. So:

• Fats with double bonds: Unsaturated (mono or poly)
• Artificially hydrogenated, harmful: Trans fats

Answer:

First blank: Unsaturated fats
Second blank: Trans fats
