The dilution factor in order to end up with 96 colonies of bacteria is 0.23 × 
.
For calculating the colony forming unit bacteria;
Colony-forming unit (CFU or cfu) is a measurement of live bacterial or fungi cells and is used to calculate the colony-forming unit of bacteria. CFU counts only viable cells as opposed to direct microscopic counts, which count all cells, both living and dead, using a hemocytometer. Colony-forming units per milliliter (CFU/mL) for liquids and colony-forming units per gram (CFU/g) for solids are used to indicate the results for convenience. The miles and Misra method can be used to compute CFU, which is helpful for assessing the microbiological load and severity of illness in blood and other samples.
∴ cfu/ml = (no. of colonies x dilution factor) / volume of culture plate
23 x cells per mL = 96 × dilution factor
Dilution factor = 23 × / 96
Dilution factor = 0.23 ×
Therefore, the dilution factor in order to end up with 96 colonies of bacteria is 0.23 × .

Fats, oils, waxes<span>, and sterols are all known as lipids</span>
Fat digestion yields fatty acids and glycerol. Protein digestion yields amino acids. Both digestive processes B. add a water molecule to break bonds.
Adding a water molecule to break bonds in fat digestion yields fatty acids and glycerol. Protein digestion yields amino acids in the digestive process.
Addition of the water molecules to break bonds is called as Hydrolysis. It is done in Fat digestion in which a water molecule is added to yield Fatty acid and Glycerol. Fatty acid is the forming component of fat in the body.
Addition of water molecule in Protein causes its absorption in the body during the digestive activity by forming amino acids that are simpler to absorb. Amino acids make up protein by forming chain of peptide bonds.
It similar to the reaction used in the breaking of bonds in carbohydrates. Proteases is the enzyme which is hydrolytic in nature carrying out hydrolysis.
Hence, the correct option is B. add a water molecule to break bonds.

Answer is B.) nonrenewable only
Nuclear energy is usually considered as renewable energy. But the material which used in the nuclear power plants is non-renewable resource. A rare type of a uranium which is U-235 is used nuclear power plants. This element is a non-renewable resource. Nuclear energy from uranium is released through a process called nuclear fission. In the nuclear fission the nucleus of a uranium atom splits to give energy.
