Acidity in human sweat is an example of<u> </u><u>innate immunity</u>

Explanation:

Sweat arising from human skin is acidic in nature with a pH ranging between 4.5 to 7.

As part of innate immunity, the skin acts both as a physical barrier and chemical shield.

As part of chemical shield, the skin’s sebaceous glands present on the skin produces an oily substance called sebum which contains free fatty acids. Further, hair follicles on skin releases lactic acid which bind with the amino acids of the proteins present on the keratinized layers of skin. The acidity of the sweat is due to the combined action of free fatty acids, lactic acid and the amino acids present on the skin.

This natural acidic nature of skin creates a hostile acidic environment to pathogens which prevents their entry into the body.

Mrrafil [7]

Answer:

In taxonomy, binomial nomenclature ("two-term naming system"), also called binominal nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages.

Bone can be classified as a connective tissue because it contains an extracellular matrix that surrounds widely spaced cells. Tr
kotykmax [81]

Answer:

False. Bone can be classified as a connective tissue because it provides support and structure to the body.

Explanation:

Connective tissue is those tissues that fill spaces between organs and other tissues, and also provide support to the organism. It is characterized by the presence of different types of cells separated by intercellular material synthesized by them.

The bony tissue is the principal structural and supportive connective tissue that differs from the other connective tissues because its extracellular matrix is mineralized, which makes it possible to accomplish its support and protection function due to its rigidity and hardness. The mineral that deposits in the osteoid matrix is the calcium phosphate, composing hydroxyapatite crystals. The bony tissue is a storage site of calcium and phosphate, which are available for maintaining constant the calcium blood levels according to the individual physiological needs.
