Additional compounds can be added to agar before sterilization (or sometimes after). an example of this is "milk agar," in which

2% nonfat powdered milk is added to the agar base. lactose-digesting bacteria like to grow on milk agar. how many grams of nonfat powdered milk should be added to 125 ml of lb agar to end up with 2% milk lb agar? show your calculations.

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.

Which statements apply to density? Check all that apply.
Alenkasestr [34]
The only statement on the options that says true about density is:
> The density of an object determines whether it will sink or float.

Why?
Density is a physical property of an object.
Density is not derived as a unit of measure. It is derived from 2 fundamental units: kg and m.
The Density of an object is not constant.
Density is calculated by dividing the mass by the volume of an object.

Which statement best describes the energy changes associated with evaporation and boiling
KIM [24]

Atoms gain energy during evaporation and boiling

When a liquid begins to boil, it means its molecules and atoms are gaining increased kinetic energy and the molecules are getting further apart and the liquid is beginning to turn to gas.

Explanation:

Gas begins to form in the liquid and lift to the surface as bubbles and escaping into the atmosphere.  The vapor pressure of the liquid also overcomes the atmospheric pressure in this stage allowing the change of phase. This can only occur as long as the molecules and atoms of the liquid continue to gain energy. This is the reason that even though you keep heating the liquid, it remains at its boiling point temperature as it changes phase.  This energy is referred to as the latent heat of vaporization.

What is the relationship between carcinogens and mutations? How does this in turn affect the development of cancer?
Oksi-84 [34.3K]

Answer:

Relation between mutagens and carcinogens. Mutagenicity and carcinogenicity are clearly correlated. One study showed that 157 of 175 known carcinogens (approximately 90 percent) are also mutagens. The somatic mutation theory of cancer holds that these agents cause cancer by inducing the mutation of somatic cells.

Science Question
Dmitrij [34]

The question is incomplete as the image and options are not given, however, the correct image and options are as follows:

A. If liquid Material A is in contact with gaseous Material A and the volume of the gas increases, the gas’s temperature will increase.

B. If liquid Material A is in contact with gaseous Material A and the volume of the gas increases, the gas’s temperature will decrease.

C. When the temperature of gaseous Material A increases, its volume will increase.

D. When the temperature of liquid Material A increases, its volume will increase.

Answer:

The correct answer is - C. When the temperature of gaseous Material A increases, its volume will increase.

Explanation:

The figure and table related to the given question are attached with the answer that shows the volume change during the time period in relation to temperature and the phase of material also changes with an increase in temperature.

According to Figure 1, it is clear that initially, Material A was in the liquid phase and after a certain temperature, it is constant at a phase of a mix of liquid-gas and finally entirely in the gas phase from Time 22 sec to Time 24 sec. as temperature increased and the volume of Material A also increased according to the table 1.

So the hypothesis C is correct.
