Question

Does the sun have ori the skin to cause cancer?

O Sunburn removes the upper layers of the skin.
O Chemicals from the sun change the skin cells.
O The heat from the sún interrupts the cell cycle.
O The Sun's rays cause mutations in the skin cells.

Answer 1

Skin cancer is primarily caused by UV radiation from the sun which damages the DNA in skin cells, potentially leading to mutations and the growth of tumors. Protective measures such as sunscreen and clothing are vital to mitigate this risk.

Step-by-step explanation:

The sun emits ultraviolet (UV) radiation, which has been identified as a primary factor in the development of skin cancer. The two main types of rays that contribute to skin damage and cancer risk are UV-A and UV-B. Exposure to these rays can lead to DNA damage in skin cells, which is one of the starting points for the development of skin cancers such as basal cell carcinoma, squamous cell carcinoma, and melanoma.

UV radiation from the sun can cause mutations in the skin cells by damaging the genetic material (DNA). When the DNA of a cell is damaged, it may result in the cell growing out of control, leading to the formation of a tumor. This risk is higher with increased sun exposure, and therefore it is important to protect skin from the sun by wearing sunscreen with high SPF, protective clothing, and hats.

While sunburn can strip away the upper layers of the skin and heat from the sun can affect the skin, it is the UV-induced mutations that directly contribute to the formation of skin cancer. Therefore, the correct answer to the question is that the Sun's rays can cause mutations in the skin cells.
