The word in the blank should be 'segregation' :)
Answer:
When organisms use urea, ammonia is generated during incubation, which makes the reaction of these media alkaline
Explanation:
Urea broth preparation:
Suspend 3.87 grams of the medium in 100 ml of distilled water without heating. When the powder dissolves, sterilize by filtration. Dispense quantities of 0.5 to 2 ml in small sterile tubes. Larger volumes may be used but the reactions will be slower. Do not sterilize in autoclave.
Do not boil the medium.
If no filter is available, the medium can be sterilized at 100-110 ° C for 10 minutes. If the medium is prepared and inoculated immediately, it provides good results without sterilization.
Answer:
it would be C, D, E
A is a mixture
B is a mixture
C is a pure substance because Oxygen gas by the chemical symbol O2, is strictly pure
D is pure substance because Gold is one of the basic elements found naturally in nature, and as such, in its pure form
E is a pure substance because Both ice and liquid water are the same substance. H2O Though ice water is a mixture of both solid and liquid it is a pure substance, based on the molecular structure of its components .
F is a mixture

Answer: Gut microbiome degrade the ingested milk sugars through a biochemical pathway, producing ATP required for the energy needs of infant.
Explanation:
The human breast milk fed on by infants contains a high concentration of indigestible oligosaccharides which include lacto-N-tetraose and lacto-N-fucopentaose.
These milk sugars are utilized by microbes in the gut of infants, yielding lactate as the final product of metabolism and releasing several molecules of ATP as useful energy for use by the infant.
Thus, the presence of these gut microbes at birth, and the feeding of infant with breast milk is vital to fulfilling their energy needs
