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>

Answer:
100% of the progeny will be speckled
Explanation:
<u>Available data:</u>
- Three colors: dark brown, light brown, and speckled.
- The genotypes for these colors are BB for dark brown, bb for light
brown, and Bb for speckled.
Cross: dark brown crab with a light brown crab
Parentals) BB x bb
Gametes) B B b b
Punnett square)
B B
b Bb Bb
b Bb Bb
F1) Genotype:
4/4 = 100% of the progeny will be heterozygous for the trait, Bb
Phenotype:
4/4 = 100% of the progeny will be speckled
