Answer:
the life cycle of a frog consists three stages : first stage is egg and second stage is larva and the final stage is adult
Answer:
In eukaryotes, it occurs in the chloroplast. In prokaryotes it does it in the cytoplasm.
Explanation:
Prokaryotes don't have organelles such as the mitochondria and the chloroplast, it just has cell membrane, which its only function is to protect the cell and is unable to generate chemical processes; the DNA, which stores and manages only the genes, which would be affected if exposed to a chemical process like photosynthesis; and the cytoplasm, which stores the materials that the cell needs, where photosynthesis occurs. Eukaryotes have chloroplasts, which absorb the sunlight and combine it with carbon dioxide and water to realize photosynthesis.
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.
