Answer:

The correct answer is - transformation.

Explanation:

Griffith's experiment was performed by Fredrick Griffith with Streptococcus pneumoniae. Streptococcus P. are rough non encapsulated streptococci that are converted into smooth encapsulated streptococci bacteria in presence of heat-killed smooth encapsulated bacteria.

This experiment was the first experiment that showed that this bacteria can get DNA by the process of transformation.

He suggested that the nonencapsulated bacteria had been transformed into the encapsulated smooth bacteria strain by the transformation process that was somehow part of the dead encapsulated strain bacteria.

Thus, the correct answer - transformation.

Answer:

Cardiac output = 20 L/min

Explanation:

The cardiac output of a person refers to the volume of blood the heart pumps in a minute. The normal range for cardiac output is about 4 to 8 L/min. However, this can vary depending on the metabolic needs of the individual at any instant of time, for example, it is higher when exercising than  when resting.

Cardiac output is calculated from the product of the stroke volume in liters/min and the heart rate in beats/min

Cardiac output  = stroke volume * heart rate

For the individual who is running; stroke volume = 100 mL/beat or 0.1 L/beat

heart rate = 200 beats/min

Cardiac output =0.1 L/beat * 200 beats/min

Cardiac output = 20 L/min
