During which of the phases of growth, does the number of new cells balance the number of declining cells?

The correct answer is stationary phase.

Explanation:

There are four phases in a growth curve lag, log, stationary, and death phase. During the lag phase, cells adapt to the new environment and no growth occurs. During the exponential phase, cells grow at an exponential rate.

The stationary phase is the phase where the number of cells remains constant because the number of production of new cell becomes equal to the number of cell death. This phase shows that the culture reached its carrying capacity.  

During the death phase, the number of cells starts declining because of the declining resources. Therefore the correct answer is the stationary phase.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'

there is not 1 highest source of protein, but there are many; meats, fish, poultry, seafood, cheese, eggs, yogurt and milk. the only non complete animal food that is beneficial is gelatin.

sorry if this did not , have a great day!
