What is a metric system?The metric system is a measurement system that employs the meter, liter, and gram as base units of length (distance), capacity (volume), and weight (mass).
The meter, gram, and liter are the three most common base units in the metric system.
This name is derived from the Greek word metron, which means "measure."
The physical standard for the meter was to be built to equal one ten-millionth of the distance between the North Pole and the Equator along the meridian running between Dunkirk, France, and Barcelona, Spain.
The kilogram, kilometer, and kilocalorie all share the property of being 1000 times larger than a base unit in the metric system.
Thus, the correct option is c.

A football player gets tackled during the game, which of the following body systems is responsible for protecting their organs?
circulatory system
reproductive system
skeletal system
nervous system
Answers
Answer:
Skeletal system
Explanation:
the bones of the skeleton protect the internal organs and reduce the risk of injury on impact. For example, the cranium protects the brain, the ribs offer protection to the heart and lungs, the vertebrae protect the spinal cord and the pelvis offers protection to the sensitive reproductive organs.
Answer:
I believe your best choice from the given choices above would be C) skeletal system. The bone structure within the human body, such as the rib cage for instance, provides protection for our organs and takes more impact rather than any of our organs. Without our skeletal system, we would have zero protection for our organs, increasing the chance of more internal body damage.
