Answer:
Explanation:
The higher temperature is the factor which is responsible for the process of denaturation of proteins in which the breaking down of hydrogen, disulphide bonds and destabilization occurs. This process breaks up the bond between the polypeptides.
The bovine pancreatic trypsin inhibitor comprises of 58 amino acids this consists of the disulphide bonds which are destroyed on heating as a result of this the inhibitor becomes inactive. But on cooling it comes to the original form as the internal structure starts making hydrogen and disulphide bonds again. Thus the activity of the BPTI again gets restored.

Answer:
in the S phase of the cell cycle
Explanation:
<em>Scientists isolate cells in various phases of the cell cycle. They find a group of cells that have 1.5 times more DNA than G1 phase cells. The cells of this group are _____.</em>
The cell cycle has two main stages which is the interphase and the M phase.
While the M phase is characterized by active division, the interphase consists of G0 phase which is entirely a resting phase for cells that do not need to divide ordinarily, G1 phase which is a phase for cell drowth and development, S phase which is a phase for DNA synthesis or replication and G2 phase which is a phase for protein synthesis.
Hence, cells in the S phase and G2 phase of the cell cycle are expected to have more DNA than cells in the G0 and G1 phase.
<em>Essentially, the amount of DNA is doubled in the S phase. Therefore, if the cell group have 1.5 times more DNA than G1 phase cells, it means the cells are still in S phase.</em>
