Answer:

POLLUTANT, SOURCE AND IMPACT

Carbon Monoxide

SOURCE:- carbon monoxide main sources are from our homes, eg; wood stoves and fire place, generators, gas stoves, kerosene heaters, leaking chimneys, tobacco smokes etc

IMPACT:- carbon monoxide can cause organ failure as it reduces the amount of oxygen the hemoglobin been carried in the red blood cells to this organs in our body.

Carbon dioxide

SOURCE:- carbon dioxide can be from both human and natural source. Example of the sources includes; natural source ( ocean release, decomposition and respiration), human activities ( burning of coal, oil and natural gas, cement production etc)

IMPACT:- carbon dioxide causes difficulties in breathing as it displaces oxygen in the air.

It also increase the greenhouse effect (global warming) as more heat energy gets trapped by the atmosphere causing the planet to become warmer.

Sulphur dioxide

SOURCE:- sulphur dioxide mainly occur due to human activities such as fossil fuel combustion at industrial facilities, in ships etc.

IMPACT:- Sulphur oxide has been linked to many health effect and diseases such as cardiovascular diseases. It also causes respiratory problems, asphlegm and asthma attacks, irritation of lungs, throat and nose as well.

Nitrogen oxides

SOURCES:- nitrogen oxides also comes from human activities such as; combustion of fossil fuel, making of nitric acid, refining metals as well as petrols, explosive, food manufacturing etc.

IMPACT:- Nitrogen oxides has also been linked to many respiratory health issues such as bronchitis and wheezing. It causes the lining of the lungs to inflame there by reduce the immunity of the lungs to respiratory diseases.

Methane

SOURCE:- methane can be from either natural or human activities. The natural source includes; food digestion by cattles, decay of organic materials. Human activities such as waste management, rice production, oil and gas production etc.

IMPACT:- Methane is considered a green house gas like carbon dioxide, it contributes to the trapping of heat energy in the atmosphere which causes global warming. It is also linked to serious health issues such cardiovascular, respiratory and neurological problems.

Particulates

SOURCE:- particulates are fine tiny particles of matter found in the air, it might be in solid or liquid form. Example; dust, smoke, fumes etc. This particles can suspended in the air for an extended periods of time.

IMPACT:- exposure to particulates can cause variety of respiratory health problems such as difficulties in breathing, coughing, lungs and heart problem etc.

What impact does the atmosphere have on the Earth’s cycles? Check all that apply. produces wind currents
bazaltina [42]

Answer

The Impact that the Atmosphere has on the Earth’s cycle is it moves oxygen and carbon dioxide through the biosphere and transfers water into Earth’s oceans.

Explanations

The two main activities which affects the Earth’s cycle are the carbon cycle and water cycle. The increase in greenhouse gases in the Atmosphere has resulted into the greenhouse effect especially the amount of temperatures experienced on the surface of earth. An increased temperature has caused changes to the environment and ecologies.

Define the terms skeletal muscle fiber, motor unit, skeletal muscle twitch, electrical stimulus, and latent period.
Leya [2.2K]
Skeletal muscle fiber is a muscular tissue that is attached to the skeletal system. the skeletal muscle fibers are striated muscles i.e have striations in their structure. The skeletal muscle fibers are voluntary muscles i.e they can be controlled.

Motor unit is a composed of a motor nerve cell attached to a muscle fiber with its axon terminals. Motor nerve cells or neurons are the types of neurons that send impulses from the central nervous system to the responding organ. The muscle fiber may be attached to many neurons not only one neuron. Collectively, all the neurons attached to the same muscle fiber are called motor pool.

A skeletal muscle twitch is the contraction of a muscle fiber in response to the minimum stimulation.

The electrical stimulus is the stimulation of a skeletal muscle fiber by using external electrical impulses. The electrical stimulus is important in many sporting and medical situations.

A latent period is a period between applying a stimulus to a muscle fiber and the response of this muscle fiber by contraction.
