Explanation:

Continuing education is a practice aimed at training and developing human resources in an organization. Through short courses employees have the ability to recycle their knowledge and acquire new skills in other areas of knowledge.

i mean, there is a lot of homeless people. but it is a very busy place and always in need for people who can be busy so it's not impossible to find one.

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.'
