Water molecules are polar, having partially positive and partially negative ends.
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.
The presence of protein in the urine is called proteinuria. Proteinuria is an indicator that THE KIDNEYS' FILTRATION MEMBRANE HAS BEEN DAMAGED.
It is the work of the kidneys to filter the blood and remove all the waste products while conserving the materials needed in the body. When body materials such as protein begin to come out with urine in excess of the normal quantity expected, then that means that the kidney is not filtering the blood very well again and this is usually due to damage in the kidney glomeruli which perform the process of filtration.
If there are respiring organisms within that sample of air, the partial pressure of oxygen decreases because the organisms utilize it for respiration activities.
