Answer:
effector
Explanation:If the value is not at the set point or is outside the normal range, the control center sends a signal to the effector. The effector is an organ, gland, muscle, or other structure that acts on the signal from the control center to move the variable back toward the set point.
Answer:
antibodies being produced to fight off a pathogen inside the body
Explanation:
Specific immune responses, also known as the adaptive immune system are ways the body fights against pathogens. The body is able to identify cells that are unique to it. When pathogens bearing an unknown identity enter the body, antibodies are released to attack the antigens on the surface of these pathogens.
The body usually develops this immunity after a previous attack by the pathogen. Lymphocytes known as the B and T cells are released by the immune system t engulf the pathogens.
Biochemical tests and use of media allow physicians to identify
the type of bacteria causing a disease (such
as whether its gram+ or gram-) and use appropriate
antibiotic effective against the bacteria. Another clinical significance is to
determine the resistance of bacteria to antibiotics (this is conducted using susceptibility tests).
We could possibly use water as a fuel source, rather than fossil fuels (which are limited)
Science has already developed something of the sort, and with using water as a fuel source for say vehicles and such, it's inevitable for a positive change to happen because there would be less carbon monoxide; which means less polution.
