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.

Connective tissue.
- tissue that provides structure, support, and protection to other human tissues and organs. In addition to helping to transport nutrients and other substances between tissues and organs, connective tissue also helps to store fat and mend damaged tissue. A gel-like substance, fibers, and cells make up connective tissue.
- connective tissue is a set of tissues found throughout the body that help to keep the body and its organs in shape as well as to give internal cohesion and support. The more specialized and recognized variations—bone, ligaments, tendons, cartilage, and adipose (fat) tissue—as well as a variety of fibrous tissue types that differ only in density and cellularity are included in the connective tissues.
- The majority of the organs in the abdominal cavity are connected to the abdominal wall by a membrane strip called the mesentery.
Therefore, the correct answer is connective tissue.

Answer: A. A blockage in the aorta
Explanation:
A heart attack happens when one or more aorta or coronary arteries get blocked. With the passage of time, the coronary artery becomes narrow that is because of the deposition of various substances such as fat, cholesterol and other reserves. This restricts the smooth circulation of blood hence results in heart attack or heart stroke.
Answer:
All of the above is the answer.
