Which of the following statements best
reflects the connection between the specific
and non-specific immune systems?
-Nonspecific immunity is designed to deal only
with microbes that are not a threat to the
body, whereas, the specific immune system
only deals with microorganisms that cause
infection.
-Nonspecific immunity is designed to finish the
job that the specific immune system started
-The nonspecific immune system is designed as
a first line of defense against microorganisms,
while the specific immune system uses
antibodies to attack specific antigens.
-The nonspecific immune system deals with
microorganisms that the specific immune
system can't deal with.

The statement that best reflects the connection between specific and non-specific immune systems is that nonspecific immune system is designed as  a first line of defense against microorganisms,  while the specific immune system uses  antibodies to attack specific antigens.

Explanation:

The non-specific immune system is a response that organizes the body's defense against attack from any harmful agent, trying in the first instance to eliminate it. The non-specific response is natural and innate, and examples of this response are mechanisms such as sneezing, coughing and inflammation.

The specific immune system is acquired, and requires exposure to a harmful agent - called an antigen - to develop an appropriate response to attack that agent, such as the production of specific antibodies.

For this reason, the first barrier of defense is provided by the nonspecific immune system, and then the specific immune system acts.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
