Biological barriers are mechanisms within the body that prevent harmful microorganisms from entering and causing infection. Examples include the skin acting as a physical barrier and the acidic environment of the stomach killing ingested pathogens.
Biological has two definitions. Biological is an adjective meaning "of or relating to biology or living organisms" Biological is also a noun meaning "a therapeutic substance derived from biological sources."
Interspecies reproduction is generally rare among organisms, as most species have specific genetic and biological barriers that prevent successful mating and offspring production between different species.
"Biological island" is a term given to the last of a species that is on its way to extinction. These species require intense human intervention in order to avoid becoming a genetic dead end, where adaptation and survival cease and the species dies out.
Movable concrete barriers found on freeways are typically referred to as "barrier transfer machines" or "moveable median barriers." These barriers can be shifted to create a safer environment for road maintenance or changing traffic conditions.
The cost of human cloning is currently unknown as it is not a legal or widely practiced procedure. Additionally, the ethical and scientific challenges associated with human cloning make it a controversial topic with significant barriers to its widespread application.
security barriers
Biological barriers are factors that prevent species migration, interbreeding, or free movement. What determines the barrier depends on the species and it's method of movement. For some species biological barriers are physical like bodies of water, mountains, or deserts.

Barriers to migration refer to obstacles or challenges that individuals face when trying to move from one place to another, such as legal restrictions, lack of resources, cultural differences, or physical barriers like borders or bodies of water. These barriers can make it difficult for people to relocate or seek better opportunities in other areas.
Significant barriers refer to obstacles or challenges that can impede progress, success, or access to a particular goal or opportunity. These barriers often require concerted effort or resources to overcome.
If your sperm impregnates her then you are the biological father if your not sure get a DNA test.
The process of flux through a membrane helps substances move across biological barriers by allowing them to pass through the membrane from an area of high concentration to an area of low concentration. This movement is driven by the natural tendency of substances to reach equilibrium, where the concentration is the same on both sides of the membrane.
In a biological context, "mean" typically refers to the average value of a set of data points. It is used to summarize and compare quantitative observations within a population of organisms or biological samples. Calculating the mean helps researchers understand central tendencies and variation in biological phenomena.
Bio means living - biological, therefore, means pertaining to living things.
I means your biological father.
