Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Unsaturated fats are liquid at room temperature as they have double bonds. Saturated fatty acids have single bond and are solid at room temperature. Polyunstaurated fats are good for health as they boost up the good cholestrol level. As they are liquid so they do not choke the blood vessels and they are easily metabolized. Polyunsaturated fats include omega-3 and omega-6 fats. These are essential fatty acids that the body needs for brain function and cell growth.

So, the correct answer is option D.

  2. Fats

  3. Monosaccharides

  4. Starch
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The excess carbohydrates and proteins are stored in the body as fats. It gets converted into energy during excessive physical work. Essential fatty acids are those fatty acids which play an important role in the biological process and they can be metabolized easily. These acts as a fuel rather getting deposited as fat in the body. The human body cannot synthesize essential fatty acids. Unsaturated fats are liquid at room temperature as they have double bonds. The essential fatty acids are unsaturated as they have double bonds. Saturated fatty acids have the single bond and are solid at room temperature.

So, the correct answer is option B.
