<span>One of the key ideas in biology is that structure always impacts function. For one, a neuron has a long axon because it helps to transmit signals from cell to cell, allowing the nervous system to function. Secondly, epithelial cells are long and thin, which allows them to cover numerous organs in the body. Finally, muscle cells are more rod-shaped and are comprised of contractile units which allows them to withstand the wear and tear of muscle movement.</span>

Plants use photosynthesis to get there energy from the sun. Chlorophyll is what’s inside of the plant that turns energy into useable carbon dioxide and water.
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.
