Correct Answer is D

Explanation

A. Unsaturated fats (HDL): High-density lipoprotein (HDL) is considered "good cholesterol" because it helps remove LDL cholesterol from the blood, reducing the risk of heart disease.

B. Omega-3 fatty acids: Omega-3 fatty acids are healthy fats that reduce inflammation and lower the risk of heart disease by improving heart health.

C. Omega-6 fatty acids: While excessive omega-6 intake may contribute to inflammation, they are not the primary contributors to plaque buildup in blood vessels like saturated fats (LDL).

D. Saturated fats (LDL): Saturated fats increase low-density lipoprotein (LDL), also known as "bad cholesterol," which contributes to plaque buildup in arteries and increases the risk of heart disease.

A. Bilirubin B. Carotene C. Keratin D. Melanin

Correct Answer is D

Explanation

A. Bilirubin: Bilirubin is a yellow pigment derived from the breakdown of red blood cells, associated with jaundice rather than freckles or moles.

B. Carotene: Carotene is an orange pigment found in foods like carrots and can contribute to skin tone but is not the main factor in moles or vitiligo.

C. Keratin: Keratin is a structural protein found in skin, hair, and nails but does not influence pigmentation.

D. Melanin: Melanin is the pigment responsible for skin color, moles, freckles, and conditions like vitiligo, which causes depigmentation.
