The lactose-digesting bacteria like to grow on milk agar .Bacillus cereus growth and survival were examined during the production of cheese of the Gouda variety. Approximately 102 B. cereus spores per milliliter of cheese milk were intentionally added to pasteurized milk before it was used to make the cheese in the pilot plant.
"milk agar," in which 2% nonfat powdered milk is added to the agar base. lactose-digesting bacteria like to grow on milk agar. Surface plating on B. cereus selective medium was used to count B. cereus, while lactic acid bacteria were counted on lactic agar and MRS agar (de Man-Rogosa-Sharpe). Samples of the milk before renneting, the curd at cutting, the half-whey removal, the final whey removal, the hooping of the curd, the cheese after pressing, the cheese after brining, after one week, after two weeks, after four weeks, and after six weeks were all taken for microbiological analysis. The growth of lactic acid bacteria during cheese production was unaffected by B. cereus.

Lthough much of the explanation for why certain substances mix and form
solutions and why others do not is beyond the scope of this class, we
can get a glimpse at why solutions form by taking a look at the
process by which ethanol, C2H5OH, dissolves in
water. Ethanol is actually miscible in water, which means that the two
liquids can be mixed in any proportion without any limit to their
solubility. Much of what we now know about the tendency of particles
to become more dispersed can be used to understand this kind of change
as well.
Picture a layer of ethanol being carefully added to the top of some water (Figure below).
Because the particles of a liquid are moving constantly, some of the
ethanol particles at the boundary between the two liquids will
immediately move into the water, and some of the water molecules will
move into the ethanol. In this process, water-water and
ethanol-ethanol attractions are broken and ethanol-water attractions
are formed. Because both the ethanol and the water are molecular
substances with O−H bonds, the attractions broken between water
molecules and the attractions broken between ethanol molecules are
hydrogen bonds. The attractions that form between the ethanol and
water molecules are also hydrogen bonds (Figure below). There you go
Cellulose serves as a skeleton for plants
The collective effective dose is the sum of the individual doses received in a given period by a specific population from exposure to a specific source of radiation. It is the dose Quantity S, calculated as the sum of all individual effective doses over the time period or during the operation being considered due to ionizing radiation. It may be used to estimate the total health effects of a process or accidental release involving ionizing radiation to an exposed population.
Answer:
Puppies from the same litter commonly share 50% of their genes (on average.) Each litter mate randomly inherits 50% of its genes from his father and the other 50% from his mother. The only thing here is that they do not necessarily the same 50% from each
