Amember of the board who is a top executive of the firm is called a(n) a. co-manager b. inside director c. outside director d. executive manager

B) inside director

Explanation:

An inside director is a member of the board of directors that is also an employee of the company. Usually inside directors should be part of the top management of the company, but in some particular cases that may not apply (e.g. in European cooperatives unions are represented by one member in the board).

It doesn't matter if the directors are inside or outside directors (don't work in the company), they all have a duty of care to the company.

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.'
