Answer:

The correct answer is option D.

Explanation:

The outer surface of body defenses is nonspecific, which means they do not attack specific pathogens. Skin is the very first immune system against nonspecific pathogens. Other than mucous membranes also act as a barrier to pathogens and produce chemical defenses.

Saliva also provides a non-specific external response as it contains mucus, antibacterial compounds and various enzymes to target bacteria and other pathogens.

Thus, the correct answer is option D.

A boy received one dominant allele for brown hair from his father and a recessive allele for blonde hair from his mother. ​Which
Damm [24]

Well say the father had the genotype BB (dominant brown) and his mom had the genotype bb (recessive blonde).

If the boy got only one allele of brown hair and his phenotype is brown hair, then his genetic type is Bb

He is heterozygous (has two different alleles). But since brown hair is dominant, his phenotype is brown hair. But he does have the blonde recessive allele.

Hope this helps!
