If a project needs one earth mover six months from now in order to complete one activity, and the organization has four such machines, there is no equipment resource constraint.
(a) true
(b) false

(A) True

Explanation:

A constraint occurs when the resources are scarce in respect to their requirement.

Here, the resources are 4 times that is one machine is required 6 months from now, and already the current availability is of 4 machines.

Thus for each one activity one earth mover is required which means we have plenty of resources in the form of such machine at present thus there is no scarcity or constraint of resources.

Thus, the given statement is

True

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.'
