The percentage of skin aging that is caused by the rays of the sun is approximately
- A.
50 to 65 percent
- B.
60 to 65 percent
- C.
70 to 75 percent
- D.
80 to 85 percent
Correct Answer
D. 80 to 85 percentExplanation
The correct answer is 80 to 85 percent. This means that the majority of skin aging is caused by the rays of the sun. Sun exposure can lead to the breakdown of collagen and elastin in the skin, causing wrinkles, sagging, and other signs of aging. Protecting the skin from the sun's harmful rays by wearing sunscreen and seeking shade can help prevent premature aging.Rate this question:

The UV rays of the sun reach the skin in two different forms which are
- A.
UVA and UVB rays
- B.
VBC and ABA rays
- C.
UVA and ULB rays
- D.
UVB and ABB rays
Correct Answer
A. UVA and UVB raysExplanation
The UV rays of the sun reach the skin in two different forms, UVA and UVB rays. UVA rays are longer in wavelength and can penetrate deeper into the skin, causing premature aging and wrinkling. UVB rays are shorter in wavelength and primarily affect the outer layer of the skin, causing sunburn and increasing the risk of skin cancer. Both UVA and UVB rays can be harmful to the skin, so it is important to protect oneself from exposure to both types of rays.Rate this question:

The UVA rays that are deep- penetrating and can go through a glass window are
- A.
Sun rays
- B.
Aging rays
- C.
Light rays
- D.
Ultra rays
Correct Answer
B. Aging raysExplanation
UVA rays are deep-penetrating rays that can go through a glass window. These rays are responsible for causing skin aging, such as wrinkles, fine lines, and age spots. They can also contribute to the development of skin cancer. Therefore, the term "aging rays" accurately describes UVA rays and their effects on the skin.Rate this question:

Wrinkling and sagging of the skin are caused by weakening collagen fibers and
- A.
Protein fibers
- B.
Tissue fibers
- C.
Elastin fibers
- D.
Dermis fibers
Correct Answer
C. Elastin fibersExplanation
Wrinkling and sagging of the skin are caused by weakening collagen fibers and elastin fibers. Collagen provides structural support to the skin, while elastin allows the skin to stretch and bounce back. As we age, the production of collagen and elastin decreases, leading to a loss of elasticity and firmness in the skin. This results in the formation of wrinkles and sagging. Therefore, the correct answer is elastin fibers.Rate this question:

UVB rays contribute to the bodys synthesis of vitamin D and other imoirtant
- A.
Absorption
- B.
Minerals
- C.
Elements
- D.
Rejuvenation
Correct Answer
B. MineralsExplanation
UVB rays contribute to the body's synthesis of vitamin D, which is essential for the absorption of minerals. Vitamin D helps the body absorb calcium and phosphorus, which are important minerals for bone health. Without sufficient vitamin D, the body may not be able to properly absorb these minerals, leading to potential deficiencies and health issues. Therefore, UVB rays indirectly contribute to the absorption of minerals by promoting the synthesis of vitamin D.Rate this question:

Daily moisturizers or protective lotions should have a sunscreen with an SPF of at least
- A.
5
- B.
6
- C.
10
- D.
15
Correct Answer
D. 15Explanation
Daily moisturizers or protective lotions should have a sunscreen with an SPF of at least 15 because SPF, or Sun Protection Factor, measures the level of protection against the sun's harmful UVB rays. An SPF of 15 means that the product can block about 93% of UVB radiation, while higher SPFs provide even more protection. This is important to prevent sunburn, premature aging, and reduce the risk of skin cancer. Therefore, an SPF of 15 is the minimum recommended level for effective sun protection in daily moisturizers or lotions.Rate this question:

Sebum from a comedo exposed to the enviornment turns black and
- A.
Closes
- B.
Opens
- C.
Oxidizes
- D.

Correct Answer
C. OxidizesExplanation
Sebum is an oily substance produced by the sebaceous glands in the skin. When a comedo, also known as a blackhead, is exposed to the environment, the sebum inside it reacts with the oxygen in the air. This reaction causes the sebum to undergo oxidation, resulting in a dark or black color. Therefore, the correct answer is "oxidizes".Rate this question:

A chronic skin condition characterized by inflammation of the sebaceous glands is
- A.
Freckles
- B.
Acne
- C.
Tumors
- D.
Milia
Correct Answer
B. AcneExplanation
Acne is a chronic skin condition characterized by inflammation of the sebaceous glands. It typically presents as pimples, blackheads, whiteheads, or cysts on the face, chest, back, or shoulders. The sebaceous glands produce an oily substance called sebum, which helps to lubricate the skin. However, in acne, the sebaceous glands become overactive, leading to clogged pores and the growth of bacteria. This causes inflammation and the formation of acne lesions. Freckles are small brown spots on the skin, tumors are abnormal growths, and milia are small white bumps. None of these conditions involve inflammation of the sebaceous glands like acne does.Rate this question:
