Answer: 1) Recessive allele is unable to express its effect in the presence of dominant allele WHILE a dominant allele is able to express itself even in the presence of its recessive allele.
2) Recessive allele produces its phenotypic effect only in the presence of a similar allele. E.g; tt is dwarf. WHILE a dominant allele does not require another similar allele to produce its effect on the phenotype. E.g; Tt is tall.
3) Recessive allele forms a defective polypeptide or enzyme so that the expression consists of absence of the effect of dominant allele. E.g; white flower colour in Pea. WHILE a dominant allele can form a complete polypeptide or enzyme for expressing its effects. E.g; red colour of flower in Pea.

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.
