Answer:
B. The rating number means it will protect you that many times longer than without sunscreen
Explanation:
The sun protection factor is a comparison between the length of time it will take for a skin that has no sunscreen to begin reddening compared to a skin with sunscreen applied. Therefore, the ratings is an indication of the length of time a person will be protected from ultraviolet rays than when the individual has no sunscreen applied.
While higher SPF's are believed to offer more protection against UV rays, the added protection is usually just a negligible amount. They are very important for the skin and protect the body against diseases like cancer.

Explanation:
Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. In eukaryotic cells, t
Genus represents taxonomic rank above species and below family. When organisms belong to the same genus, they must be of the same phyla, but may be in different species. In binomial nomenclature it is the generic name shared by the group of close relative.
Chondromalacia is the synonymous of the cartilage softening (chondro = cartilage, malacia = soft). It's a pathology of softening affecting the joints and more particularly those of the knee (kneecap and femur).
This anomaly can be observed in several circumstances:
• the first is that of direct trauma. It is the cartilaginous lesion occurring before the fracture (fissure) of the cartilage.
• the second is that of common osteoarthritis. It is highly likely that the first stage of osteoarthritis begins with edema (swelling of the cartilage or closed chondropathy) that makes the cartilage less resistant and more vulnerable; this soft cartilage can then crack on its surface (open chondropathy) and these cracks will be more difficult to heal.
