Serjik [45]

Answer:

transformation

Explanation:

Transformation is one of the three methods of genetic recombinant in bacteria. The other two are transduction and conjugation. Transformation occurs when the bacterial cells take up the DNA and which in turn changes their phenotype.

Transformation requires that there should not be any cell to cell contact. In the experiments performed by Griffith, the heat-killed virulent S strains were mixed with live R strains. The R strain took the DNA of heat-killed S strains which in turn converted them into the virulent strains. Since this horizontal gene transfer did not include any cell-to-cell contact, he called the process transformation.

Kryger [21]

Answer:

The correct answer is direct calorimetry.

Explanation:

A method of attaining direct determination of the concentration of heat produced by the body inside an insulated chamber, which is sufficiently big to allow moderate amounts of work is termed as direct calorimetry. These chambers within which the measurement is done is also known as the whole-room calorimeters.  

The mentioned process provides the measurement of the energy discharged in the form of heat.
