If a pathogen breaches these barriers, the innate immune system provides an immediate, but non-specific response. Innate immune systems are found in all animals . [ 2 ] If pathogens successfully evade the innate response, vertebrates possess a second layer of protection, the adaptive immune system , which is activated by the innate response. [ 3 ]

The decolorization step is critical and must be timed correctly; the crystal violet stain is removed from both gram-positive and negative cells if the decolorizing agent is left on too long (a matter of seconds). [19] After decolorization, the gram-positive cell remains purple and the gram-negative cell loses its purple color. [19]
Interactive animation of the structure of ATP. Adenosine triphosphate (ATP) is a nucleoside triphosphate [2] that provides energy to drive and support many processes in living cells, such as muscle contraction, nerve impulse propagation, and chemical synthesis.
As a result, disabled people came to be regarded as a problem, to be solved or erased. [22] In the early 1970s, the disability rights movement became established, when disability activists began to challenge how society treated disabled people and the medical approach to disability. Due to this work, physical barriers to access were identified.
Pearson's correlation coefficient is the covariance of the two variables divided by the product of their standard deviations. The form of the definition involves a "product moment", that is, the mean (the first moment about the origin) of the product of the mean-adjusted random variables; hence the modifier product-moment in the name.
The demand for timely, high-quality fire information has increased in recent years. Fast and effective detection is a key factor in wildfire fighting. [136] Early detection efforts were focused on early response, accurate results in both daytime and nighttime, and the ability to prioritize fire danger. [137]
Almost forgot: REgarding Superm401's question - yes, some air will redissolve back into the water when it cools, but the difference is that the rate of freezing is significantly higher than the rate at which the air dissolves. --HappyCamper 03:24, 3 December 2005 (UTC) (exdenting for readability) Quiz question: Why are icicles clear?
