Answer:
Etest
Explanation:
The Etest is used for sensitivity testing particularly for anaerobic microbes. In the test, the agar medium in a single plate is streaked in three different directions with the microbe under study.
The plastic Etest strips are arranged on the surface of the medium in such a way that they appear radiating out from the center of the plate. Each of the plastic Etest strip serves as source for different antibiotics. The plate is incubated to allow the elliptic zone of inhibition to appear which in turn are used to determine the MICs.
The correct answer is A. Provides body tissues with oxygen
Explanation:
The respiratory system includes different organs such as the lungs, diaphragm, trachea, etc. that allow organisms especially animals to exchange gases that are necessary to survive. This mainly occurs as oxygen is taken from air or water in the case of fish and other aquatic animals and this provides the body tissues with oxygen that is necessary for multiple processes and at the same time it takes out the carbon dioxide through exhalation. Considering this, it can be concluded the respiratory system provides body tissues with oxygen.
