Definition of experiment

Answer;

-the scientific fields, medical fields, or technical fields

Explanation;

-There are two main systems of measurement in the world: the Metric system and the US standard system.

-The Metric (or Decimal) system is made of units based on powers of 10. To convert units, one needs to move the decimal point.The prefix (beginning part of the word- i.e. kilo or milli) describes the size of the given unit.

Final answer:

Three professional areas in the U.S. that use the metric system are science and scientific research, manufacturing and engineering, and medical and healthcare.

Explanation:

Three professional areas in the U.S. that use the metric system are:

1. Science and Scientific Research: Scientists and researchers in fields such as chemistry, physics, and biology use the metric system extensively for accurate and standardized measurements.
2. Manufacturing and Engineering: Industries involved in manufacturing and engineering, including automotive, aerospace, and machinery, use the metric system to ensure consistency and compatibility in their products.
3. Medical and Healthcare: In the medical field, healthcare professionals use the metric system for measurements of weight, height, dosage, and other medical calculations.

Answer and Explanation:

The spread of measles was halted from spreading by developing a vaccine. This is a type of active artificial acquired immunity where the antibodies are formed in the response to administration of dead or attenuated pathogens or toxoids through vaccination. Vaccination protects humans from infections of many diseases. Examples include tuberculosis, poliomyelitis, whooping cough, diphtheria and measles. Measle vaccine is administered 9 months after birth through subcutaneous injection.

Answer:

The real answer to this question is about 10% of the stored energy of one level becomes stored energy at the next level higher.

Think about it, when a consumer eats the producer it also consumes the energy the producer stored and as the food chain grows the energy is passed through all. The only time the energy is released into heat is when a consumer dies and decomposes, and even then all of the energy isn't released.

Also took the quiz

The choice that is true of the energy that is passed from one trophic level to the next in a food chain is about 10% of the energy passed from one level to the next is released as heat.

Final answer:

The addition of another person at each end of the rope does not affect the results of the tug of war.

Explanation:

The addition of another man at each end of the rope does not affect the results of the tug of war because the forces exerted by each individual are independent of each other.

In a tug of war, the force applied by each person depends on their individual strength and the technique used to pull the rope.

The total force exerted on the rope is the sum of the individual forces, and it remains the same regardless of the number of people at each end.
