What is the main prerequisite for clearance at the G2 checkpoint?
Katena32 [7]

Answer:

The correct answer will be option-accurate and complete DNA replication.

Explanation:

The cell cycle of a cell is controlled by the internal checkpoints where the cell cycle halts until the favourable conditions appear. These checkpoints are G1 checkpoint, G2 checkpoint and M checkpoint.

The G2 checkpoint asses that the DNA replication has been completed, all the chromosomes have been replicated and the replicated DNA is not damaged. The cell cycle stops if the replicated DNA is found damaged.

Thus, option-accurate and complete DNA is the correct answer.

What is the volume of 0.25 mol of ammonia gas at 1.00 atm and 273 K? (R= 0.0821 Latm/molK)What is the volume of 0.25 mol of ammo
ICE Princess25 [194]

Answer:

5.6L

Explanation:

Given parameters:

number of moles  = 0.25mol

pressure on gas  = 1atm

temperature  = 273K

Gas constant R = 0.0821Latm/molK

Unknown:

Volume of gas  = ?

Solution:

Using the ideal gas equation, we can solve this problem. The equation is a combination of the three gas laws: Boyle's law, Charles's law and Avogadro's law.

It is mathematically expressed as;

             PV = nRT

where P is the pressure

           V is the volume

          R is the gas constant

          T is the temperature

          n is the number of moles

All the parameters are in the appropriate units and we simply solve for the volume of the gas;

                1 x V = 0.25 x 0.0821 x 273

                      V  = 5.6L

Although macroscopic observations of microbial growth can provide much valuable information, microbiologists often follow such o
melisa1 [442]

Answer:

Explanation:

As a microbiologist there are different methods are devised for characterization of microbes.such as Macroscopic analysis and microscopy method.

With the help of microscope the needed information about the individual cell such as individual cellular characteristics can be obtained, the magnification help to provide the features such as size, shape and motility of the microbes which helps to know the specific microbes characters.

When handling an unknown environmental microbe, with help of the cell characteristics of the microbes obtained using the microscope, the identity as well as metabolic characterization can be known such as the type of environment the microbes can survive in(aerobic or anaerobic), the source of food.

No growth was observed on the control plate.

The growth on the control plate indicates that the aseptic technique devised in the model was an adequate method for the prevention of the control plate from been contaminated.
