At the center of the colorful cloud formed from the gases of the dying stars is a second star ( magnetar ) which is the most powerful star in the galaxy due to its  magnetic force.

Hence we can conclude that the thing that makes kes73 interesting to astronomers is the presence of a second star

strojnjashka [21]

Answer:

True

Explanation:

It is correct to say that the deeper in the ground we go, the older things get. This statement is specifically valid in a terrain that has not been disturbed by tectonic activities.

<em>According to the law of superposition of strata "in a sequence of sediment, the oldest layer is usually at the bottom and the youngest is on top provided the area is undisturbed". </em>

Based on this law of superposition of strata, it clearly seen that the deeper we go down in the earth, the older things get.

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.
