Which section of the project charter publicly acknowledges the commitment of the sponsor, managers and team members to the project? a. decisions and findings b. contract section c. signatures and commitment d. business case

The correct answer is letter "C": signatures and commitment.

Explanation:

A Project Charter is the document that makes official the beginning of a project and officially names the manager of the project and defines the main objectives and restrictions that the executive must achieve. Thus, it is one of the most important documents in the beginning phase of the project.

The commitment of the sponsor, managers, and team members is recorded in the signature and commitment area of the project where investors, executives, and employees confirm they will drive all their efforts to reach their common goal.

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
