What appropriately describes innate immunity?
The general pathogen fighting system people are born with that does not change over time
The process in which endothelial cells are separated away from each other, making the capillaries larger
The process by which the body automatically reacts to tissue injured by trauma or bacteria
The set of proteins that enhance the ability of the body to initiate the inflammatory response, attack a pathogen, and remove damaged cell material
The Correct Answer is A
A. The general pathogen fighting system people are born with that does not change over time:
Innate immunity is nonspecific, present at birth, and provides immediate defense without adapting to specific pathogens.
B. The process in which endothelial cells are separated away from each other, making the capillaries larger:
This describes vascular permeability, a component of inflammation, not a definition of innate immunity.
C. The process by which the body automatically reacts to tissue injured by trauma or bacteria:
This describes the inflammatory response, which is a mechanism of innate immunity, but not the full definition of innate immunity itself.
D. The set of proteins that enhance the ability of the body to initiate the inflammatory response, attack a pathogen, and remove damaged cell material:
This describes the complement system, which is part of innate immunity, but again, it is not the complete definition of innate immunity.

Correct Answer is A
Explanation
A. There is no known safe level of alcohol use during pregnancy or when trying to get pregnant:
Research has shown that any alcohol consumption during pregnancy can potentially cause fetal alcohol spectrum disorders (FASD). There is no safe amount.
B. Alcohol prior to conception cannot impact the fetus:
Alcohol use prior to conception can affect fertility and early embryonic development, especially since many pregnancies are unrecognized during early stages.
C. Alcohol exposure is most dangerous during the last trimester:
All trimesters are critical, but the first trimester is often considered the most vulnerable for teratogenic effects, especially for organ formation.
D. Fetal alcohol exposure increases the likelihood of twins or other multiples:
Alcohol exposure does not increase the likelihood of multiple births; it causes developmental abnormalities.
