Correct Answer: B. bacterium

Correct Answer: D. births over deaths

Correct Answer: D) operating system

Explanation

The motherboard is a hardware component that connects all the other components of the computer together, but it does not manage or coordinate activities. Application software refers to programs that perform specific tasks, such as word processing or gaming, but it also does not manage or coordinate activities. RAM, or random access memory, is a type of computer memory that stores data temporarily, but it does not manage or coordinate activities either.

System software refers to programs that manage the computer's hardware and provide a platform for other software to run on. While it is responsible for managing some activities, it does not coordinate the sharing of resources between different programs.

The correct answer is option D, the operating system. An operating system is a type of system software that manages the computer's hardware and software resources, and provides a platform for other software to run on. It also coordinates the sharing of resources between different programs, ensuring that each program gets the resources it needs to function properly.

In summary, the correct option for the component responsible for managing and coordinating activities, as well as sharing resources in a computer is the operating system.

Correct Answer: B) Average cost is at the minimum

Explanation

This question is about the relationship between average cost and marginal cost. Average cost is the total cost of producing a good or service, divided by the quantity produced. Marginal cost is the additional cost of producing one more unit of a good or service. The question asks when the average cost is equal to the marginal cost.

The correct answer is Option B: Average cost is at the minimum. When the average cost is at its minimum, it means that the cost of producing each additional unit is decreasing. This also means that the marginal cost is equal to the average cost at that point.

If the average cost is at the maximum (Option A), it means that the cost of producing each additional unit is increasing, so the marginal cost will be higher than the average cost. If the marginal cost is at the minimum (Option C), it means that the cost of producing one more unit is at its lowest point, but this does not necessarily mean that it is equal to the average cost. Finally, if the marginal cost is at the maximum (Option D), it means that the cost of producing one more unit is at its highest point, so it will be higher than the average cost.

Understanding the relationship between average cost and marginal cost is important in economics because it helps businesses determine the optimal level of production and pricing for their goods or services.

Correct Answer: B. MC

Explanation

Monopolies make profits by creating prices that are higher, and output that is lower. Profits would be eliminated when price is equal to marginal cost. That is the cost incurred by a firm by producing one additional unit of a product or service. The monopoly would no longer make profits if the price it charges for its product is equal to the additional cost it incurred in producing that good.
