Select the correct answer from each drop-down menu. Identify the type of costs to complete the sentence.

The 1.) cost is the sum of fixed and variable costs. 2.) cost is the sum of fixed and variable cost, divided by production volume.

1.)Answer choices: semi variable, total, average

2.)Answer choices: marginal, average, target

1. Total cost

2. Average cost

Explanation:

1. A total cost refers to the sum of fixed cost which is the cost that do not vary with the level of output such as rent, salaries and variable cost which is a cost that varies with the level of output such as raw materials, labour etc.

When goods are produced, costs are usually expended on such production. The actual cost expended on such output is called total cost.

2. Average cost is the addition of fixed and variable cost divided by production output.

One of the factors that influence average cost is the production period. It means that increasing production in the short period might not be feasible for producers hence check the average cost both in the short run and long run inorder to decide the production best suited for each period.

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.'
