Explanation:
Electromyography
Explanation:
A diagonistic test which involves the electrical activity within muscle fibers in response to nerve stimulation is known as electromyography.
The response are usually shown on an electromyogram.
- This test is usually carried out when people are fatigued and to test muscular strength.
- Athletes and people that takes part in active sports are frequently subjected to such tests.
- In this test, the electrical activities with the muscles are recorded and displayed visually.
- The signals of the electrical activities are picked up by electrodes on the body or buried in the body.

Answer: There are three types of fossil fuels which can all be used for energy provision; coal, oil and natural gas.
Explanation:
Answer:
Troposphere is the lowest layer of Earth’s atmosphere that has undergone a large increase in temperature due to the presence of greenhouse gases.
Explanation:
Troposphere (0 to 12 km) where we live is the lowest layer of earth's atmosphere, which is closest to the earth's surface contains half of the atmosphere. Here most clouds are found and almost all weather occurs. Atmosphere contains approximately 78% of nitrogen , 21% of oxygen and 0.9% of argon. Gases like carbon dioxide, nitrous oxides, methane, ozone and the water vapor constitutes the rest of the atmosphere. Many small particles called aerosols are also there which include dust, spores, pollen, volcanic ash, smoke etc.The greenhouse effect is a natural phenomenon that keeps the temperature on the earth suitable for supporting life. The greenhouse gases includes both natural and man-made gases like carbon dioxide
, methane, nitrous oxide, chlorofluorocarbons, hydrochlorofluorocarbons, ozone, water vapour. They absorb radiation in the atmosphere and create the green house effect. The thermal infrared radiation emitted by the Earth’s surface and the atmosphere is absorbed by greenhouse gases. They trap heat within the surface-troposphere system preventing it from escaping back into space. This is called the greenhouse effect, which increases the temperature of the lower atmosphere.The increase in the atmospheric concentrations of greenhouse gases due to human activity has caused an increase in the natural greenhouse effect. As a result, the atmosphere is trapping too much heat which increases the temperature of the Earth.
