Answer:
D. Serial dilution followed by a colony forming units calculation.
Explanation:
The best way to count bacterial cells such as Salmonella accurately is through serial dilution and calculation of colony forming units.
Serial dilution is made using a petri dish containing appropriate culture medium for Salmonella growth. In this petri dish, with the help of an inoculation loop, the suspension containing the Salmonella will be scratched in the middle of the petri dish. Then, the inoculation loop will be passed over the salmonella streaks and will be dragged to the other side of the plate, where the loop will be scratched halfway through this space. The inoculation loop should again pass over the new salmonella streaks and be dragged through the rest of the petri dish. Then one must wait for the bacterial colonies to grow inside the plate.
Once these colonies are grown, those that appear in isolation will be counted through a specific calculation for the count of salmonella colonies.
Answer:
C) Respiration
Explanation:
an organelle present in both plant and animal cells. it is where the process of cellular respiration takes place. ... the process which both plant and animal cells use to release energy for the cell to use (ATP) from food molecules such as glucose. the equation for this process is: C6H12O6 + 6 O2 > 6 CO2 + 6H2O.
Right there are 440 known species of sharks around the world right now discovered by humans so far there are more sharks around the world that we hadn't discovered yet. Here are some sharks: Hammerhead Sharks, Sand Sharks,Saw Sharks, Carpet Sharks and much more.
Answer:
Sunlight, water, and carbon dioxide
Explanation:
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
