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.

A solution with HCl would likely have a low pH and a high pOH. Hydrochloric acid or HCl, from the name itself is acidic its pH is always below neutral pH or 7. pH is the measure of the concentration of hydronium ions (H3O+) in a solution while pOH is the measure of the concentration of hydoxide ions (OH-) in a solution. A relationship exist between the two values of a solution where pH + pOH = 14 therefore when the pH is low, consequently, the pOH is high.

Which body cells always or sometimes carry out the anaerobic energy extraction pathway? A. Red blood cells and muscle cells. B.
ExtremeBDS [4]

Answer:

A. Red blood cells and muscle cells.

Explanation:

Cellular respiration which takes place in the presence of the oxygen is known as aerobic respiration and which takes place in the absence of oxygen is known as anaerobic respiration.

In anaerobic respiration, the cells produce a very low amount of ATP compared to the aerobic respiration but still in the human body to survive, the cells have this conserved process.

The cells in humans in which the process takes place are the red blood cells which do not possess the nucleus, the mitochondria and the other organelles so they perform anaerobic respiration. The muscle cells, when deprived of oxygen, undergo anaerobic respiration which produces a very low amount of ATP molecules and lactic acid also called fermentation.

Thus, option-A is correct.
