Norm's car, which he uses 100% for personal purposes, was completely destroyed in an accident in 2019. the car's adjusted basis at the time of the accident was $13,000. its fair market value was $10,000. the car was covered by a $2,000 deductible insurance policy. norm did not file a claim against the insurance policy because he feared that reporting the accident would result in a substantial increase in his insurance rates. his adjusted gross income was $14,000 (before considering the loss). what is norm's deductible loss?

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.'

answer: marginal utility of the fourth brownie is 0.

explanation: marginal utility is the addtional utility gained from the consumption of one more unit of a good. it is given by,

so, marginal utility at the 4th unit will be given by

since, the values are not given here, you can simply find marginal utility at fourth unit by subtracting total utility at 3rd unit from total utility at 4th unit.
