Bronchial atresia
* is thought to be a congenital abnormality.
* rare anomaly presenting as recurring lung infections.

Basidia
* are characteristic of the Basidiomycetes
  - in extensive fertile layer which are susceptible to rain when exposed
  - located at the ends of tiny projections within the mushroom cap
* occur elsewhere on the fruiting bodies of non-gilled fungi.
* produce four spores at the end of microscopic spines called sterigma.

Biological concept
* Some biological concepts rely on reproduction.
* have important limitations

Behavioral research
* is also critical to public health
  - similarly important for understanding and treating severe mental illnesses
* refers to studies of the behavior of individuals or behavior of aggregates.
* shows that children influence the purchasing decisions of parents, too
  - most boys have different inclinations, different emotions from girls

Blastomycosis
* can affect the lungs, bones, and skin.
* can cause rapid changes in the eyes
  - respiratory signs such as difficulty breathing, tiring easily or coughing
* fungal disease caused by Blastomyces dermatitidis
  - infection involving the lungs and occasionally spreading to the skin
* has a well-defined endemic area where it is found.
* is an uncommon, but potentially serious fungal infection
  - diseases
  - more common in the upper Midwest
  - mycosis
* is primarily a disease that infects people and dogs
  - lung infection, but occasionally it spreads through the bloodstream
  - treated with anti-fungal medication
  - usually a slow-growing infection involving the lungs and the skin
* occurs only in North America and Africa.
* rare fungal infection.
* starts out as a lung infection caused by inhalation of the conidia.

Benevolence
* is good willing, or the love of being and of happiness
  - good, but altruism is evil because it requires sacrifice
  - impossible in a society where people violate each others' rights
  - kindness

* Some boas live in deserts
  - underground holes while others live in trees
* defend themselves by striking.
* live in tropical areas, forests, grasslands, and deserts.
* vary in color from brown to gray with irregular saddles down the entire dorsal body.

Behavioral adaptation
* allow an animal to respond relatively quickly to environmental challenge.
* are a change in behavior that allow a species to better survive
  - complex and variable and show an evolutionary relationship to landscapes
  - important for winter survival too
  - inherited behaviors
  - the things animals do to survive
  - thing organisms do to increase their chance to survive and reproduce
* can be a response to some external stimulus
  - as simple as moving from place to place
  - either genetic or environmental
* is as important as physical health in puppies.
* is the learned behavior-something the animal does to survive
  - way an organism acts or behaves to stay alive
* works in other ways, too.

Biomedical research
* commitment to life.
* continues to improve the quality of our lives, but it involves risk
  - pave the way toward better diagnostics, treatments, and cures
* encompasses virtually all areas of the life sciences.
* form of biological research.
* funded by the federal government is public health.
* involves the world of medicine.
* is an approach used towards solving medical problems.
* is essential for enhancing human health and well being
  - to the future of medicine
  - the foundation of a good public health system
* provides fundamental information about living things.
