Explanation:
Sebaceous glands linked to your hair follicles secrete the oil that coats your scalp.
Option a is correct.
<h3>Which gland produces a substance that is secreted into a hair follicle?</h3>
The skin's sebaceous glands are known for producing oil. Their secretion, known as sebum, is released through tiny ducts that open into the hair follicles and lubricates both the skin and the hair.
<h3>Test your knowledge of the relationship between sebaceous glands and hair follicles.</h3>
A hair follicle's related oil glands secrete sebum onto the hair shaft. It prevents hair from splitting and becoming brittle while also lubricating and waterproofing the stratum corneum layer.

Answer:
Explanation:
Active - the process of exposing the body to an antigen. Exposing the body will generate an adaptive response that takes a few days or weeks to develop and can be life long lasting.
Passive - it is provided when we are given antibodies to disease. Instead of producing the antibodies with the immune system, they are given. Like a newborn baby acquires immunity from the placenta.
Natural - it works to fight off pathogens before they begin an active infection. Sometimes it is not enough to stop the pathogen or the pathogen exploits the immune response and gets to the cells.
Life expectancy is a generalization for a specific generation or peoples in a given era. People born between the late 90s to early 2000s have a greater live expectancy than say peoples 300 years ago. We are “expected” to live until about our late 70s, early 80s because we as a society have the means to keep us living longer. Someone who dies before that window, may have had some complications with their health that prevented them the estimated age.
