Which of the following is a barrier against pathogens provided by the skin?
Alexxandr [17]

Answer:

Low pH

Explanation:

The skin has sebaceous glands that secrete sebum. Sebum makes a protective layer over the surface of the skin and imparts it an acidic pH due to the presence of fatty acids in it.

Mostly, the pH level of skin is maintained within the range of 3-5 (acidic) which in turn serves as one of the barriers against pathogen provided by skin. Likewise, sweat glands of skin secrete sweat which also imparts the acidic pH to the skin to prevent any infection.

For a dominant/recessive trait, do the offspring of identical parents always look like the parents?
Mashcka [7]

Answer:

No, they don't always look like the parents.

Explanation:

They won't always look like the parents because from each parent, they will receive different dominant and recessive traits. In addition, certain traits skip generations or don't get passed down. For example, you can have 2 parents with red hair and have dark brown hair, but have a child who DOES have red hair.
