Answer:
I think its sharply focused ultrasound but I'm not sure
Explanation:
A fish finder utilizes high frequencies of sharply focused ultrasound, which is transmitted with high voltage in order to determine the direction fish schools are moving. Locating objects in the air is different than locating objects in the water. I hope this helped ♡.
1. Enterococcus and coliforms can enter the water through feces. Although a water sample is negative for these bacteria, it could still be infected by pathogens from other sources than feces.
2. Culture media are sterilized by filtration because they could contain antibiotics or serum which deteriorate upon heat. Filtration is used in sanitation to remove large particles.
3. In the membrane filter technique, it is assumed that <span>all viable bacteria will form colonies. This means that formed colonies develop from the viable bacteria so that the number of colonies suggests the number of bacteria.
4. E. coli is negative for Citrate and Voges-Proskauer tests, and is positive for Indole and Methyl red tests.
5. The answer is yes because eo</span><span>sin-methylene blue agar is inhibitory to Gram+ bacteria.</span>
Slow movment is called slow mo
The most likely result is that in such conditions would be the reduction in the number of animals, plants and fishes that were in water.
