Ann is trying to decide which one of two job offers she will accept. several items are presented below: job offer a(1)base salary $50,000(2)overtime compensation is comp. time(3)moving allowance $3,000(4)signing bonus $2,000(5)job search costs incurred $300job offer b(1)base salary $50,000(2)overtime compensation is hourly rate(3)moving allowance $3,000(4)signing bonus $0(5)job search costs incurred $500select the items that are irrelevant to ann's decision.

1)Base Salary $50,000

(3)Moving allowance $3,000

(5)Job search costs incurred $300 Job Offer

Explanation:

In this scenario, the person who is trying to decide for a job change will look at various things that can improve their future to the greatest extent.

Like: Medical allowances, paid leaves, overtime wages, bonuses, and incentives, etc.  

Many factors are there to join a new company.  

Based on the situation, the overtime compensation, and the signing bonus are the reasons to accept the job offer.

And, the remaining reasons like - basic salary, moving allowance are the service which is the same for most of the companies. The job search cost is a sunk cost that is not recovered.  

Hence, these costs will not be considered.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

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.'
