This is the chain reaction in the name polymerase chain reaction. PCR is so efficient because it multiplies the DNA exponentially for each of the 25 to 75 cycles. A cycle takes only a minute or so and each new segment of DNA that is made can serve as a template for new ones.

Nat2105 [25]

Answer:

Measure only daytime.

Explanation:

It is useless to measure the oxygen production every hour for 24 hours because oxygen is produced during day time due to the presence of photosynthesis process. Oxygen is produced in large amount during photosynthesis, some oxygen is used in respiration while the remaining diffuse out from plant body through stomata. After vanishing sunlight, the photosynthesis process stop and no production of oxygen occur. So only measure oxygen production at daytime as compared to every hour for 24 hours.

svp [43]

Answer:

Option (2).

Explanation:

The cell potential or membrane potential may be defined as the difference in the electric potential between inside and outside of the cell. The membrane potential of the cell changes during the propagation of action potential.

The resting membrane potential is -70mV. The influx of sodium ions causes the depolarization of the cell membrane. The cell potential changes from -70mV to + 30mV. The membrane potential becomes more positive during the depolarization phase.

Thus, the correct answer is option (2).
