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.

How does evidence in each of these areas of research help explain evolution (i.e. what does each of theses tell about evolution
Korolek [52]

Answer:

Biogeography: Animals can come from certain areas and move to other areas causing their adaptations and therefore traits to change.

Radioactive Dating: The time zone fossils come from can be dating to certain times where there species may have changed. This can also be said for Fossils.

Comparing anatomy and development: There characteristics of certain biological features can differentiate species and their traits to determine which animal has came from another and other relative species.

Genetics and Molecular Biology: Genes can be passed onto on another and looking at genes passed down from one species to the next determines evolution of traits.

The hydrolysis of atp on the na+/ k+ pump results in
Shalnov [3]
I believe it results to a conformation change that moves the Na+ binding site to the inside of the cell. ATP hydrolysis involves the release of chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate.For example in muscles. The process of moving sodium and potassium ions across the cell membrane is an active transport process involving the hydrolysis of ATP to provide the necessary energy. It involves an enzyme referred to as Na+/K+ ATPase.

Which is an example of active transport?
Tju [1.3M]

Active transport is a type of transport that requires energy to move substances across a membrane. It occurs against a concentration gradient.

  • The use of energy to move waste materials out of a cell is an EXAMPLE of transport active.

  • Active transport occurs against a concentration gradient, whereas passive transport (i.e., diffusion) occurs in favor of a concentration gradient.

  • Active transport can be mediated by membrane proteins that move substances from an area of high concentration to an area of low concentration.

  • This movement (active transport ) usually requires the energy provided by the hydrolysis of ATP.

  • Water molecules move across cellular membranes through membrane protein channels called aquaporins that act in favor of a concentration gradient (passive transport).
